春花生超高产生育动态及生理特性研究
Study on Growth Dynamic and Physiological Characteristics of Super-high-yielding Spring Peanut
摘要
Abstract
Under the field condition, the growth dynamics and physiological characteristics of spring peanut were studied at the yield level of 9 ton per hectare. The results showed that the vegetative growth of peanut mainly concentrated in the earlier growing stages. The leaf age, number of branches, stem height and lateral branch length reached the peak during 50 ~ 60 days after emergence and basically stopped increasing during 90 ~ 100 days. The leaf area index reached the peak on the 90th day after emergence with the peak value of 5.8. The days with the leaf area index greater than or equal to 3 were about 65. The chlorophyll content and dry matter accumulation also reached the peak on the 90th and 100th day respectively after emergence. The variation of SOD, POD and CAT activities and soluble protein content in leaves were basically uniform showing a single peak during the growth period, while the content of MDA increased gradually.关键词
