Effects of H2S and rhizobia on osmotic adjustment
substances of soybean plants under water deficiency
Compared with control, Q8 and Q8+NaHS treatments increased the sucrose
content to varying degrees under any water content conditions. With the
decrease of water content, the sucrose content of control, Q8 and
Q8+NaHS treatments had different degrees of increase (Fig. 8A). Our
results showed that the changing trends of fructose and sucrose content
were very similar, the fructose content in leaves displayed a tendency
to increase with the decreases of water content, which was markedly
enhanced by Q8 and Q8+NaHS treatments (Fig. 8B). Glucose content also
exhibited a significant increase by Q8 and Q8+NaHS treatments under
three water conditions. Meanwhile, with the decrease of water content,
excepted for NaHS treatment, the glucose content showed different
increases in the other three treatments (Fig. 8C). In addition, In
addition, we also found that the PRO content was increased to varying
degrees by the four treatments with the decrease of water content, while
the PRO content was sharply increased by Q8 and Q8+NaHS treatments under
SW conditions (Fig. 8D). With the decrease of water content, the GB
content was elevated by Q8+NaHS treatment, and the GB content of Q8 and
Q8+NaHS treatments were higher than that of control treatment under
three water conditions (Fig. 8E).
