采用大田小区试验,在6个种植密度和5种施肥水平的不完全方案下,研究优质杂交冬油菜新品种湘杂油763的油菜叶片叶绿素含量和产量的变化。叶片叶绿素含量的测定结果表明:在同一种植密度条件下越冬期和盛花期叶片叶绿素a、叶绿素b和总叶绿素含量均随施肥量的增加而增加。同一施肥量下,只有越冬期叶片叶绿素a含量随着密度的增加而减少,叶绿素b和总叶绿素含量无此规律。叶片叶绿素与籽粒产量之间极显著正相关。

Studies on the changes of grain yield and the chlorophyll contents in the functional leaf of a new hybrid winter oilseed rape variety（Xiang hybrid No.763） under the tretments of 6 planting densities and 5 fertilizer application levels in the field plot experiment.The results of chlorophyll determination showed that,the contents of chlorophyll a,chlorophyll b and total chlorophyll during the winter and flowering stages increased along with the increase of fertilizer application amount under the same planting density.The content of chlorophyll ...
