The content of amylum could be a judgement standard for rooting ability of cuttings.
插穗的淀粉含量可以作为生根能力的判断标准之一。
The rooting ability at 4 th leaf and at top tillering can be used as selection criterion in rice breeding for drought resistance.
可将4叶期和分蘖盛期的发根力作为选育或筛选杂交中稻强抗旱性品种的参考指标。
No QTL was found to affect significantly the rooting ability of cuttings and field growth simultaneously, implying probably the difference in genes responsible for the two types of traits.
没有检测到与扦插和生长均相关的QTL，表明两类性状可能受不同的基因位点控制。
The results indicated that the rooting ability of transgenic plants was enhanced. Endogenous hormones(IAA, GA3)derived from roots, stems and leaves were significantly different from controls.
结果表明：转基因植株生根能力强，根、茎、叶各部位内源激素（IAA、GA3）与对照差异明显；
Variation in rooting ability is mainly affected by gene additive effect. Selection for rooting capacity and its utilization is effective and individual selection is more effective than family one.
生根能力的差异主要受基因加性效应控制，对生根能力选择利用效果明显，单株选择较家系选择效果好，其中以全同胞单株选择利用潜力最大。
