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).
