Lily is regarded as one kind of the most economically important cut flowers in China. In this paper, lily cultivar ‘Aladdin’ ( Lilium longiflorum × Lilium asiatic ) was chosen as experimental material for its distinct high propagation coefficient in nature and three main conclusions were achieved. Firstly, our observation results revealed that the noticeable propagation coefficient of ‘Aladdin’ depended on strong capacity to form many underground stem axillary bulbils positioned on underground node of plant after 70 days of cultivation and having 1 cm flower buds. Secondly, in terms of physiological changes, zeatin riboside (ZR) relative concentration, soluble sugar and starch content peak when and where such bulbils are forming. Finally, two KNOX family Lilium genes were sequenced completely and one BELL family gene was sequenced partly; besides, there might be an interaction between KNOX-2 and BELL protein to accomplish their functions in bulbils organogenesis according to qRT-PCR results. As far as we know, it is the first time to study the formation mechanism of lily underground stem axillary bulbils. We illustrated physiological and molecular profiles, as well as offered a new prospect to lily molecular breeding in the future.

Lilium browniivar.viridulumis a popular natural health product that combines medicine and food. However, the lack of high-quality and efficient propagation technology has been a significant impediment to the development of theL. browniivar.viridulumindustry. In this study, bulb scales ofL. browniivar.viridulumwere used as materials to investigate the induction of bulblets from scales, as well as the proliferation and enlargement of the induced bulblets. An in vitro regeneration system forL. browniivar.viridulumwas successfully established. The most effective methods for scale disinfection were found to be 75% alcohol disinfection for 30 s and 10% Sodium Hypochlorite (NaClO) disinfection for 15 min. The recommended medium for scale differentiation was Murashige and Skoog (MS) + 0.05 mg·L−11-Naphthaleneacetic acid (NAA) + 0.25 mg·L−1Thidiazuron (TDZ) + 0.05 mg·L−1kinetin (KIN) + 30 g·L−1sucrose + 6 g·L−1Activated Charcoal (AC). The recommended medium for bulblet proliferation was MS + 1.5 mg·L−16-benzylaminopurine (6-BA) + 0.5 mg·L−1NAA + 30 g·L−1sucrose. The recommended medium for bulblet enlargement was Modified MS Medium (potassium dihydrogen phosphate (KH2PO4, KDP) doubled) + 90 g·L−1sucrose. Bulblets with diameters of 1.5 cm were transplanted, and the germination rate was 100%. This study established a systematic in vitro regeneration system forL. browniivar.viridulum, which will provide the foundation for industrial production ofL. browniivar.viridulumbulbs and improvement through genetic transformation.

Abstract Lignin removal from lignocellulosic materials plays a great role in the utilization cellulose with high efficiency. In order to improve the quality of reconstituted tobacco sheet, lignin existed in tobacco stem was removed by enzymatic hydrolysis with laccase enhanced by weak alkali treatment together with the addition of Tween 80 into laccase treatment system. It is found that lignin was partially removed by laccase. The treatment of tobacco stem with NaHCO 3 resulted in the dissolution of lignin, and hence increased the porosity and specific surface area of the pretreated tobacco stem. Consequently, laccase could access to the tobacco stem more completely. The surface activity and dispersion of Tween 80 improved laccase activity, solubilization of degraded products of lignin, and contact interface between laccase and tobacco stem. The synergistic action of laccase, weak alkali and Tween 80 improved the ratio of lignin removal significantly, reaching as high as 40.3%. Graphical Abstract

The main active component ofPolygonatum sibiricum(P. sibiricum) rhizome isPolygonatum sibiricumPolysaccharide (PsP) with antioxidant function. At present, only the mature rhizome ofP. sibiricumis used to extract PsP, while the young rhizome of by-product is discarded directly as waste, resulting in significant wastage ofP. sibiricumresources. We used ultrasound-assisted extraction-deep eutectic solvents (UAE-DESs) method to extract PsP of young and mature rhizomes, respectively. The extraction rate, structure composition and antioxidant ability of PsP between young and mature rhizomes were compared, so as to provide references for comprehensive utilization ofP. sibiricumresources. The PsP extraction rate (33.88 ± 1.95%) of young rhizome was close to that (45.08 ± 1.92%) of mature rhizomes. The main component (PsP-2) of the PsP in young rhizome contained six kinds of monosaccharides, which belonged to acidic polysaccharides. The above characteristics of the PsP of young rhizome were similar to those of mature rhizome. The PsP of young rhizome also exhibited similar biological activity to that of the mature rhizome, which indicated even more advantages in DPPH free radical scavenging ability. The results of this study support the utility of the young rhizome, consequently helping to avoid unnecessary waste and provide reference for comprehensive utilization ofP. sibiricum.

A low-cost biochar was prepared through slow pyrolysis of banana pseudostem biowaste at different temperatures, and characterized by surface area and porosity analysis, scanning electron microscopy (SEM), Fourier-transform infrared (FTIR) spectroscopy, and X-ray photoelectron spectroscopy (XPS). It was shown that the biochar prepared at low pyrolysis temperature was rich in oxygen-containing groups on the surface. Adsorption experiments revealed that the biochar prepared at 300 °C (BB300) was the best adsorbent for Cr(VI) with 125.44 mg/g maximum adsorption capacity at pH 2 and 25 °C. All the adsorption processes were well described by pseudo-second-order and Langmuir models, indicating a monolayer chemiadsorption. Furthermore, it was demonstrated that adsorption of Cr(VI) was mainly attributed to reduction of Cr(VI) to Cr(III) followed by ion exchange and complexation with the biochar.Keywords:biochar;banana pseudostem;chromium;adsorption mechanism

Panax notoginseng is highly used in traditional Chinese medicine, and its root is valued for ginsenoside contents. However, evidence suggests that other plant parts such as fruit, leaves, and stem are also potential sources of bioactive compounds. Therefore, this study aimed at providing insight into the differential accumulation of metabolites in fruit, leaf, root, and stem tissues collected from P. notoginseng. A total of 808 metabolites from 11 major metabolite classes were identified. Furthermore, 32 Ginsenosides with six conserved Ginsenosides Rg1, Rf, St-3, R1, Ro, Rc, and five conserved notoginsenosides R1, K, M, E, Rb1, were identified with differential accumulation in fruit, leaf, stem, and root tissues. Several other metabolites known for their potential roles in human health were also identified as differentially accumulated in the tissues. Furthermore, the accumulation pattern of ginsenosides in different tissues is highly suggestive of utilizing fruit, leaf, and stem tissues along with roots for value addition of P. notoginseng.

Alocasia cucullata (Lour.) Schott is a member of the Araceae family and is characterized by its unique leaf morphology and vibrant flowers; thus, it is a valuable addition to gardens and interior decor. However, A. cucullata may contain toxic compounds, including calcium oxalate crystals, lectins, and alkaloids, and their distribution within the plant tissues remains poorly understood. In this study, untargeted metabolomics was used to analyse the distribution of the bioactive compounds across the roots, stems, leaves, and guttation of A. cucullata . The toxic effects of these tissues on the MDA-MB-231 human breast cancer cell line were evaluated using the MTT assay. Microscopic techniques were utilized to examine the microstructure of the guttation and stems, and the focus was on the morphology of the calcium oxalate crystals. Liquid chromatography and ELISA kits were used to quantify the calcium oxalate and lectin contents in the various tissues. The results demonstrated that the active constituents, primarily fatty acids, phenylpropanoids, flavonoids, peptides, and alkaloids, were concentrated in the roots. Notably, guttation exhibited no toxicity and lacked both calcium oxalate crystals and significant lectin levels. This research enhances the understanding of the bioactive composition and safety profile of A. cucullata and provides a theoretical foundation for future scientific investigations and safe cultivation, with implications for both scientific and industrial applications.

Abstract Hydrothermal carbonization (HTC) combined with pelletization is an efficient upgrading process to convert biomass into energy-dense pellets. Binders usually serve an important role in the quality of biofuel pellets. Here, hydrochar was produced from tobacco stem through HTC, and was pelletized in the presence of various binders. The effect of four kinds of binders (K 2 CO 3 , CaCO 3 , xanthan gum and carboxymethyl cellulose) on the basic fuel properties, mechanical strength, moisture adsorption and combustion characteristics was investigated. The results showed that K 2 CO 3 assisted pellet had decreased compressive strength, increased hygroscopicity and high combustion residues. The compressive strength of pellets increased with increasing amount CaCO 3 binder probably due to the hardening effect of enhanced adhesion attraction forces between adjacent particles. Meanwhile, the CaCO 3 assisted pellet exhibited the lowest moisture uptake behavior. In addition, the introduction of organic binders led to improved mechanical strength, especially for xanthan binder, which could be ascribed to the formation of solid bridges and enhancement of adhesion forces between particles. TGA results suggested that the binder-assisted pellets exhibited desirable combustion characteristics such as decreased ignition temperature and increased comprehensive combustibility index. Kinetic parameters of the combustion process of binder-assisted pellets were also determined by employing the model free isoconversional Kissinger–Akahira–Sunose method. This study demonstrated that HTC of tobacco stem combined with pelletization in the presence of appropriate binders provide an alternative for solid biofuel pellets production.

Large-leaf yellow tea (LYT) is processed from both leaves and stems, resulting in a distinctive rice crust–like aroma. Tea stems may contribute differently to the aroma of LYT than leaves. This study aimed to clarify the specific contribution of stems to LYT. The volatile compounds in different components of LYT were extracted and analyzed using a combination of headspace solid-phase microextraction and stir bar sorptive extraction coupled with gas chromatography-olfactory-mass spectrometry. The results revealed high concentrations of compounds with roasty attributes in stems such as 2-ethyl-3,5-dimethylpyrazine (OAV 153–208) and 2-ethyl-3,6-dimethylpyrazine (OAV 111–140). Aroma recombination and addition experiments confirmed that the roasty aroma provided by stems plays a pivotal role in the formation of the distinctive flavor of LYT. This study offers novel insights into the contribution of stems to the aroma of LYT, which can be used for processing and quality enhancement of roasted tea.

Banana is one of the most important food crops which is generally planted in tropical countries and has beneficial applications in the food industry. A large amount of by-products such as leaves, inflorescence, pseudostem, and rhizomes serves as a source for different industries. Most of these by-products may serve as an undervalued commodity with a limited commercial value, application and in some cases, it is considered as an agricultural waste. This also paves the way to utilize a huge amount of untapped biomass and resolve some of the environmental issues. Most of the edible bananas are cultivated mainly for their fruits, thus, banana farms could generate several tons of underused by-products and wastes. The present review mainly discusses the utilization of banana by-products such as peels, leaves, pseudostem, pseudostem juice, stalk, and inflorescence in various industries as a thickening agent, alternative source for renewable energy, nutraceuticals, livestock feed, natural fibers, coloring agents, bioactive compounds, and bio-fertilizers. Banana waste serves as a potential source for the production of valuable products and preserves renewable resources and provides additional income to the farming industries.

In the present study, the effects of pretreatments with different solvents (hydrochloric acid, sodium hydroxide, and ethanol) on the physicochemical structure and pyrolysis behavior of tobacco stem (TS) were investigated. Elemental compositions analysis showed that acid washing increased the carbon content and exhibited a high removal percentage for the inorganic species. SEM, BET, and FTIR analysis showed that the pretreatments exerted different effect on the surface and microstructure. Furthermore, the pyrolysis characteristics analysis indicated that solvent pretreatment increased the initial pyrolysis temperature due to the removal of unstable volatile components, especially for the acid and alkali washing samples. Meanwhile, hydrochloric acid pretreatment increased the maximum pyrolysis rate temperature of cellulose decomposition stage and decreased the char residues due to the large removal of inorganic species, while alkali treatment produced the opposite result. Pyrolysis kinetic analysis based on Coats-Redfern method showed that F1.5 chemical reaction model can be used to describe the pyrolysis stages of TS samples and a decreased activation energy was observed during the decomposition of cellulose stage for the acid and alkali washed samples. The released gaseous products during the pyrolysis process were also monitored by using TG-FTIR technique, and the gaseous release behavior was different from each other.
