摘要:
小麦灌浆期在田间用人工遮光(光照相当于自然光照的8.3和16.7%),研究鄂恩1号等四个品种对弱光的反应。在弱光条件下,供试的四个品种均较其对照减产,其中鄂麦6号和2162两品种减产率显著高于鄂恩1号和襄麦8号。灌浆速度,叶片的光合能力、以及叶茎贮藏物质运转量不同反映了各个品种对弱光反应有差异。

The response of four wheat cultivars to antificial shading during the grain fillingstage was studied. The light intensity in the shade was about 8.3% and 16.7% of Thenatural illumination. It was observed that yields of a11 four cultivars were substan-tial
