摘要
以6个苹果品种花粉为试材,研究了培养基成分以及贮藏条件对其花粉生活力的影响。结果表明：＂摩力士＂的花粉生活力最高,其次为＂首红＂,＂绿宝＂最低;随贮藏时间延长,参试苹果花粉生活力呈先升后降趋势,贮藏2-4个月时达到最高;干燥＋冷藏的贮藏条件更有利于参试苹果花粉的贮藏;培养基成分中对参试苹果花粉发芽影响最大的因素是琼脂浓度,对花粉管生长影响最大的因素是硼酸浓度,不同参试品种花粉萌发和花粉管生长适宜的培养基组合不同。
Pollen of six apple cultivars were used as materials,effects of medium components and storage conditions on pollen viability of them were studied.The results showed that‘Mollie＇had the highest pollen viability in all six tested cultivars,followed by‘Redchief＇,with the lowest one for‘Bramley＇.The viability of pollen increased at the beginning and then declined with prolong of storage time,reaching its maximum value in 2to 4months.Dry and refrigerated storage were more favorable conditions to the pollen storage of tested apples.The most important ingredient of culture medium to the pollen germination was agar concentration and that to the pollen tube growth was boric acid concentration.The mediums with different ingredient combination were necessary to match with pollen germination or tube growth of the distinctive apple cultivars.
