Fig.1 Changes in WSC contents of different organs of wheat during grain filling in different water conditions ▲和●分别表示干旱胁迫DS条件下陇鉴19L和Q9086Q的WSC含量WSC-C;△和○分别表示灌溉WW条件下陇鉴19L和Q9086Q的WSC含量。图1 a~ 图1 d分别表示旗叶、穗下节、倒二节和倒三节的WSC含量。The symbols, ▲ and ●, represent WSC contents WSC-C of Longjian 19 L and Q9086 Q in the drought stress DS, respectively; △ and ○ represent WSC contents of Longjian 19 L and Q9086 Q in the well-watered WW, respectively. Fig.1 a- Fig.1 d show WSC contents of such organs as the flag leaf, peduncle internode, penultimate internode, and the third internode from top.
