Abstract£ºIt is a very urgent research task as the cotton premature senescence is more and more serious. It is only make clear the causes and mechanisms which induced the cotton premature senescence that we can make the reasonable prevention measures. So lots of researchers have researched cotton premature senescence in different aspects. They discussed the cotton premature senescence affected by stress surrounding, soil, planting measure and so on, analyzed biochemical reaction change in premature senescence cotton, tried to breed new varieties with molecular biology measure. This article summarized some important viewpoints about cotton premature senescence shape characters, formation causes, physiochemical reaction, and advised many reasonable and effective cultivation techniques in preventing premature senescence. Planting varieties resistant to premature senescence is the most effective measure. We should do further research to prevent drastically cotton premature senescence.
Key words: cotton; premature senescence; causes; prevention measure    [Full Text, 327KB]
