AI Technical Summary
Existing technologies lack simple, rapid, and reliable methods for screening sugarcane varieties resistant to ratooning and physiological yellowing, making it difficult to effectively solve the problem of physiological yellowing in sugarcane, which affects yield and sugar content.
A three-step method was adopted, consisting of hydroponic initial screening, soil-based secondary screening, and field verification, to screen sugarcane varieties tolerant to ratooning and physiological etiolation by simulating stress environments. Natural stress factors were simulated using stress nutrient solutions and pretreated soil extracts, and the tolerance index was calculated by combining chlorophyll content and root vigor indicators.
This method enables efficient, rapid, and accurate screening of sugarcane varieties resistant to ratooning and physiological yellowing, reducing the possibility of incorrect screening, improving the accuracy and reliability of screening, and ensuring good resistance to yellowing in natural environments.
