摘    要:利用返地卫星搭载黄瓜干种子,后经地面种植观察,测定发芽率,研究性状的变异,结果表明,卫星搭载对该黄瓜种子无损伤,发芽率同对照达100%,高空特殊条件能引起黄反后代性状的变异,株高、节间长度、叶柄长、茎粗表现正向变异。平均单叶面积和第一雌花节位趋向于正态变异,而且各性状均以有利变异为多。因此,本试验进一步证实了利用卫星搭载作物种子引起变异选育优良品系,是一种安全、有效、快速的诱变育种途径。

关 键 词:卫星搭载  黄瓜  干种子  株高  节间长度  叶柄长  茎粗  平均单叶面积  诱变育种

Abstract:Dry seeds of two cucumber generations-SP1,SP2 were planted at Yantai after they had been carried to space for studing the genetic mutation in biological characteristics and major traits.The results indicated that there was no physiological damage in seeds,and seed germination rate was 100% as well as CK.The special air condition in high space could cause positive mutation of major traits in progenies of space treatment such as plant height,node length,petiole length and stem diameter,etc.Average area of single leaf and the 1st female flower node point showed normal distribution,which provided abundant variation materials for breeding.
Keywords:recoverable satellite  cucumber  variation  space condition
