FIGURE 4.

The free amino acid contents (A) and protein accumulation (B,C) in cotton embryos under conventional management practices and two integrated management strategies at two fertility levels in 2012 and 2013. The data points represent the means, and the bars are the SEs. Characterization of proteins accumulated in the cotton embryos was calculated using sigmoid growth curves (see Materials and Methods). CM and IMS stand for conventional management practice and integrated management strategies (see Materials and Methods). ^∗ and ^∗∗ denotes significant at the 0.05 level and 0.01 level, respectively.
