It is because the vascular bundles in its rachilla and lodicules were undeveloped, the transport system was abnormal. and the lodicules absorbed and lost water difficultly.

这与其小穗轴和浆片中的维管束发育不良、辅导系统不发达、浆片不易吸水与失水等原因有关。

It showed that the vascular bundle system of rachis in wheat changed apparently under water deficit.

表明水分亏缺显著改变了小麦穗轴维管束系统的显微解剖结构。

Pot experiments were carried out to study the effect of water deficit on vascular bundle system of rachis in wheat during heading stage.

利用盆栽试验研究了水分亏缺对抽穗期小麦穗轴维管束系统的影响。
