6个籼粳杂种一代的分蘖力、株高、穗长、上部三片叶面积超过高亲值或对照(汕优63)分别达到显著或极显著水平,叶片夹角偏向小值亲本,穗颈长、叶片厚度、含水量表现双亲均值,正向或负向优势均未达显著水平。分蘖期至乳熟期的单株叶面积、叶片含氮量的正向优势均达到显著或极显著水平,叶绿素含量在分蘖盛期未表现明显的优势,抽穗期至乳熟期则显著或极显著超过高亲值或对照。各主要生育时期的过氧化氢酶活性均具有明显的优势,过氧化物酶活性前期较低。抽穗期到乳熟期则极显著超过高亲值和对照。
The tillering ability, plant height and panicle length of the six indica-japonica hybrids were significantly higher than those of the high-parent or control (Shanyou 63), and the angles of the leaves tended to be small, Long, leaf thickness, water content of parents showed the average positive or negative advantages were not reached significant level. The tillering stage to the milky maturity stage had the significant positive or the significant positive effect on leaf area and leaf nitrogen content. The chlorophyll content did not show obvious superiority at the tillering stage, and the heading stage was significantly or extremely Significantly higher than the high value or control. The catalase activity in all major growth stages had obvious advantages and the activity of peroxidase was lower at early stage. The heading date to milking stage was significantly more than the high value and control.
