摘要:
以观赏海棠春之颂、赛尔科、高原玫瑰和红衣主教品种为试验材料,分别研究了花药不同散粉处理方式对散粉时间及其对花粉活力的影响,以及花期不同阶段对花药含粉量与花粉活力的影响,旨在为观赏海棠父本花粉收集提供依据。试验结果表明:25 ℃+干燥剂的条件下,花药散粉时间显著少于其他条件(自然状态+干燥剂、25 ℃、干燥皿+干燥剂)(P<0.05),红衣主教、春之颂和赛尔科品种完全散粉分别需18,10,10 h,比其他条件缩短了10%—718%,不同散粉条件之间花粉萌发率与花粉管长度的差异性则因品种不同而不同;春之颂、高原玫瑰、赛尔科品种盛花期花粉管长度及花药含粉量(每60个花药分别达到 5 000,22 500,5 750 粒)均显著高于其他阶段(P<0.01),末花期的花粉萌发率则显著低于其他阶段(P<0.01),而其他阶段花粉萌发率之间差异不显著(P>0.05)。
Abstract:
After the plants of Malus ‘Spring Glory’, M. ‘Selkirk’,M. ‘Prairie Rose’, M. ‘Cardinal’ were taken as test materials, effects of different anther-treating manner on the duration of pollen scattering, of different flowering stages on pollen quantity, and effects of both on pollen vitality were studied, aiming to provide a basis for male pollen collection. The results showed that under the condition of 25 ℃ + desiccant, the pollen-scattering duration was significantly less than those under other conditions (P <0.05), with M. ‘Spring Glory’, M. ‘Selkirk’ and M. ‘Cardinal’ pollen scattering durations of 10,10,18 h respectively, 10%—71.8% shorter than those under other conditions. Pollen germination rate and pollen tube length varied with different varieties under different pollen scattering conditions. For M. ‘Spring Glory’, M. ‘Selkirk’, M. ‘Prairie Rose’, the length of pollen tube and the quantity of pollen scattered from anther at full flowering stage, were significantly higher than those at other stages (P <0.01), the pollen germination rate at terminal flowering stage was significantly lower than those at other stages (P <0.01), but no significant difference between pollen germination rates at the other stages (P> 0.05).
