【摘要】 本文研究了春小麦品种间杂种和种间杂种F₁代及其亲本花粉母细胞染色质穿壁运动。应用x²检验,发现不论是品种间杂种还是种间杂种,染色质穿壁的百分率与亲本之间差异不显著,表明染色质穿壁运动是自然的生理活动,与是否进行杂交无关。更多还原

【Abstract】 The intercellular migration of chromatin substance of PMCs in the interbreed hybrid and species hybrid and parents of spring wheat is studied in the present paper. According to our observations and a test of chi-square, it has been shown that the discrepancies between the percentage of intercellular chromatin migration of interbreed hybrid or species hybrid and parents are not significant. It means that the migration of chromatin substance is an inherent physiological activity. In the cells no correlation between the percentage of chromatin migration of PMCs and crossings was observed.更多还原
