Abstract:
The aim of the study was to take the photoautotrophic culture experiment in three soybean varieties (Glycine max L.) Zhonghuang 13, Zhonghuang 25 and Xindou 1 under controlled environment, discuss the growth and root activities differences of them. It was shown that some leaves of the soybean plantlets under conventional culture appeared etiolation, while the tops of the three varieties plantlets were healthy and their leaves were dark green under photoautotrophic environment whose rooting percentages all reached to 100%, the root fresh weight and the root length of Zhonghuang25 achieved the maximum values, which were 1.02 g and 481.6 cm respectively，and the root activity of Xindou 1 was the best, which was 78.62 UTTCg-1FW.h-1. There were significant differences between photoautotrophic and conventional culture in root activity of Zhonghuang 13 and Xindou 1. We can draw a conclusion that photoautotrophic culture enhances the adaptability of soybean plantlets to the natural environment, and improves the growth of them.
