What are the responses of soybean growth and development to light?
Soybean is a short-day crop, with a daylength range of 9-18 hours. The shorter the light, the more it promotes flower bud differentiation and advances flowering and maturity. When soybean grows its first compound leaf, it begins to respond to light. Generally, seedlings can complete the light stage after 5-12 days of short-day conditions. The appearance of flower calyx primordia on the plant marks the completion of the light stage. Due to long-term adaptation to light conditions in different regions, the short-day response of soybean varies considerably. Southern soybean varieties have a stronger short-day response, while northern soybean varieties are insensitive to daylength, so special attention should be paid when introducing varieties.

Induced biochemical responses in tea plant leaves after infection by the tea blister blight pathogen
The activities of enzymes such as phenylalanine ammonia-lyase, polyphenol oxidase and peroxidase, as well as the levels of proteins, proline and phenolic compounds in the leaves, were studied after tea plant leaves were infected by the tea blister blight pathogen. The study showed that in diseased leaves the activity of phenylalanine ammonia-lyase decreased, while the activities of peroxidase and polyphenol oxidase increased. Analysis of peroxidase isoenzymes by polyacrylamide gel electrophoresis using benzidine as substrate showed that healthy tea plant leaves had 4 isoenzymes, whereas
