ONCLUSION
Here we described the changes of some indexes which could reflect the influences of salt
stress. By comparing the differences between wild and cultivated soybean with the same
treatments, we found that the wild soybean (BB52) performed better. The wild soybean
displayed higher compatible solutes accumulation, RWC and K
+
/Na
+
ratio compared to the
cultivated soybean (ZH13). Therefore, the wild soybean as the wild relatives of cultivated
soybean can act as a donor for salt tolerance traits (Badridze et al., 2009). The wild soybean
has been discovered to be more genetic diversity by previous studies, too. For example, Luo
et al. put forward that the wild soybean employed different tolerance mechanisms from the
cultivated soybean (Luo et al., 2005). All of our consistent results suggesting that the wild
soybean was entrusted with better resistance and it may act as a source for us to improve the
resistance of the cultivated one or even crops either through conventional breeding or genetic
engineering breeding. Hence, our study comparing the different tolerance levels of different
soybeans provided potential resources for future breeding.
