Abstract: Potassium ions (K+) are crucial for plant growth and crop yield. However, the effects of low potassium on the growth and physiological characteristics of coconut seedlings remain poorly understood. Therefore, in this study, we conducted a hydroponic pot experiment to compare the changes in growth and leaf physiological traits of coconut seedlings under low potassium (KL) and normal potassium (Kck) conditions. Low potassium significantly reduced plant height, biomass, SPAD values of chlorophyll, as well as potassium (K) content, soluble protein (SP) and soluble sugar (SS) levels in coconut seedlings. Under low potassium conditions, the content of malondialdehyde (MDA) in the leaves of coconut seedlings increased significantly, while the proline (PRO) content decreased markedly. The activities of superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT) were significantly reduced. The levels of endogenous hormones such as auxin (IAA), gibberellin (GA), and zeatin (ZR) declined significantly, while the content of abscisic acid (ABA) increased significantly. The results indicate that low potassium has a substantial impact on the growth and physiological characteristics of coconut seedlings. Therefore, in coconut cultivation, it is essential to ensure the scientific and moderate supplementation of potassium fertilizers to meet their growth and physiological requirements.Abstract: Potassium ions (K+) are crucial for plant growth and crop yield.

Abstract: As the problems of high cultivation costs and restricted sustainable resource utilization, resulting from the complex germination characteristics of African sandalwood (Osyris lanceolata), have become prominent, this research is designed to systematically analyze these characteristics and develop a graded germination strategy. This initiative seeks to lower industrial production costs, offer solutions for mass cultivation and conservation, and facilitate the growth of associated specialty industries. Using naturally matured seeds, mechanical treatments (seed-coat removal, heat shock, pericarp removal followed by shade-drying) and chemical soaking with GA3+ kinetin (KT) at 500-1500 mg/L were evaluated. Germination percentage (GP), germination index (GI), and synchrony (GV) served as metrics, while ANOVA, Duncan's test, and effect sizes (η2, Cohen's f) were employed to identify the optimal dormancy-breaking protocol. The optimal chemical treatment was soaking seeds in 1500 mg/L GA3 + 20 mg/L KT for 24 h (GK9), achieving a germination rate of 79.77%; the optimal mechanical treatment was seed coat removal, resulting in a germination rate of 67.60% (p<0.001). To enhance the germination performance of O. lanceolata seeds, a scenario-specific, graded strategy is recommended. For precision nursery cultivation, the M1 method is adopted to avoid chemical contamination. Large-scale production should prioritize the GK9 protocol. For cultivation under stressful conditions, the synergistic effect of heat shock combined with a low concentration of GA3 is recommended for further exploration.Abstract: As the problems of high cultivation costs and restricted sustainable resource utilization, resulting from the complex germination characteristics of African sandalwood (Osyris lanceolata), have become prominent, this research is designed to systematically analyze these characteristics and develop a graded germination strategy.

Abstract: Lepista sordida, a rare edible and medicinal mushroom, is currently in short supply in the market due to its declining wild availability and limited artificial cultivation. During cultivation, it has been observed that the mycelial growth rate is slow, making it imperative to explore methods for enhancing mycelial growth. As an essential energy source for edible fungi, the efficient conversion and utilization of carbon substrates significantly influence mycelial growth and fruiting body yield. Sucrose invertase (INV1), a hydrolase belonging to the glycosidase family, catalyzes the hydrolysis of sucrose into equimolar amounts of glucose and fructose. The resulting monosaccharides can be directly absorbed by cells and utilized for energy metabolism or biosynthetic processes. Studying this enzyme will provide a theoretical foundation for investigating the mycelial growth rate of Lepista sordida. In this study, a wild strain of L. sordida was obtained through tissue isolation, and the CDS and amino acid sequences of INV1 were acquired from the Institute of Biological and Medical Engineering, Guangdong Academy of Sciences, laying the groundwork for subsequent research. Using techniques such as reverse transcription quantitative PCR (RT-qPCR), the expression responses of L. sordida under sugar-free, glucose, lactose, and PDA culture conditions were examined. The results indicated that INV1 expression was lowest in the presence of glucose, moderate under PDA and sugar-free conditions, and highest when lactose was supplied as the carbon source. This suggests that sucrose invertase in L. sordida responds to lactose conversion when lactose is the sole carbon sourc.Abstract: Lepista sordida, a rare edible and medicinal mushroom, is currently in short supply in the market due to its declining wild availability and limited artificial cultivation.
