摘  要:
以四川2010—2013年水稻主推品种和部分大面积推广品种为材料,对这些品种在旱育长龄秧条件下的秧苗分蘖能力、重高比、发根力、绿叶数及根冠比等性状进行了比较。结果表明,不同品种秧苗性状存在明显差异。变异系数从大到小依次为根冠比(31.00%)、发根力(24.52%)、绿叶数(17.22%)、分蘖数(14.01%)、重高比(10.03%)。

摘  要:
Using the main planting varieties and some large-scale recommended varieties in Sichuan from 2010 to 2013 as materials, the main traits of their seedlings under the condition of late planting, dry raise and extreme long age were studied. All biological characters, including tiller number, weight ratio, rooting ability, green leaves number and root shoot ratio had significant difference. The order of the coefficient of variation was root shoot ratio(31.00%)> rooting ability(24.52%)>green leaves number(17.22%)> tiller number(14.01%)> weight ratio(10.03%).
