比较了在果岭区匍匐剪股颖的 6个多枝条密度品种和 8个标准品种在不同时期 ,分蘖数、根干重、非结构性糖含量的变化规律。得出了以下结论 :1)品种之间的分蘖数在 7月差异显著 (P≤ 0 .0 5 ) ,但 4月、10月不显著 ,2 )品种之间根重无区 ,但春季 6个高枝条密度品种的根重比 8个标准品种的要重 ;随修剪高度降低 ,根重减少。 3)在 18个采样日期中只有两个时期的非结结构性糖的含量显著不同 ,即在相对高温期间高枝条密度品种较标准品种非结区性糖的积累量要少。
The variation rules of 6 multi-branch density varieties and 8 standard varieties in different periods, tiller number, root dry weight and non-structural sugar content were compared in the green area. The conclusions are as follows: 1) The number of tillers between cultivars was significantly different in July (P≤0.0.5), but not significant in April and October; 2) The root weight of a high shoot density variety was heavier than that of 8 standard varieties; the root weight decreased with the height of pruning. 3) There was only a significant difference in the content of non-structural sugars in two sampling periods during the 18 sampling days, indicating that there was less accumulation of non-junctional sugars in the high shoot density varieties than in the standard varieties at relatively high temperatures.
