摘要

研究了氮离子（N+）注入油菜干种子引发的当代生物学效应。结果表明:N+在3.2×1016—4.6×1016/cm2注量范围内处理不影响油菜种子发芽

以3.9×1016/cm2注量处理可提高种子出苗率和成苗率

适当注量处理可促进苗期株高、叶片数和单株鲜重的增加

对成株期叶片数、茎粗、最大叶片长和宽等生物性状以及一次有效分枝数、全株总角果数和单株产量等经济性状均具有明显的生长刺激效应。同时

离子束处理区表现出广泛的变异

变异株率达到3.2%。

Abstract

The biological effects of nitrogen ion implantation (25 keV; 3.2×1016; 3.9×1016 and 4.6×1016 ions/cm2) on rape M1 generation were studied. The results showed that the germination percent of seeds treated at N+ doses between 3.2×1016 and 4.6×1016 ions/cm2 was not significantly different from control. It was observed that the emergent seedling and survival seedling percent of treated seeds at the dose of 3.9×1016 ions/cm2 was increased. Some agronomic and yield characters

such as plant height

number of leaves

fresh weight per plant at seedling stage

number of leaves

perimeter of stem

length and width of the biggest leaf at flower stage

number of primary branches

number of silique per plant and seed yield per plant at mature stage

were improved and increased at N+ treatment zone. According to the statistical result

the mutation frequency was about 3.2% in the field.
