Strawberry buds,in which a majority of pollen had single nuclear keeping to the side,were pretreated by~(60)Co γ-rays irradiation at different doses. The irradiation effect on the callus inductivity and plant differentiation rate of strawberry anther were studied.
研究了不同剂量辐照处理花粉发育处于单核靠边期花蕾对草莓花药愈伤组织诱导率和绿苗分化率的影响。

长期以来,由于籼稻花药培养中的愈伤组织诱导率和绿苗分化率偏低,从而限制了花药培养技术在籼稻育种中的广泛应用。 如何提高籼稻的花药培养力,获得足够的花粉植株,一直是花药培养研究的中心问题。

花药愈伤组织诱导率与绿苗分化率具有显著的相关性。
There are significant correlation between induction frequency of pollen callus and differentiation frequency of green plantlets.
出愈率和绿苗分化率都随冷处理时间增加而增加,到一定程度后都又急剧下降。
Both the callus induction rate and green plantlet regeneration rate increased with increasing the cold treatment time but decreased sharply when the time reached certain degree.
直链淀粉的含量与愈伤组织诱导率、生长速率、绿苗分化率的相关均未达到显著水平。
The amylose content was not related to the callus induced percentage, growth rate or green plantlet redifferentiation percentage.
