- W2364776574 abstract "[Objective] The aim of the research was to supply experimental foundation for the field pollination and cross breeding of pear tree and discussing the physiological metabolic process of its pollens.[Method] With pollens of Yali pear,Chi pear and Dangshan pear as tested materials,the germination potential and rate of their pollens and the length of their pollen tubes in different periods were researched.[Result] The germination potentials of pollens from different varieties had significant difference on the 8th,12th,16th,20th and 24th hour.The germination potentials of Yali pear were significantly higher than that of Chi pear and Dangshan pear on the 8th,20th and 24th hour.The germination potentials of pollens from the 3 pear varieties showed different dynamic characters as the time changed.The lengths of pollen tubes from different varieties had significant difference on the 4th,8th,12th,16th,20th and 24th hour.The lengths of pollen tubes from Yali pear were significantly longer than that of Chi pear and Dangshan pear on the 4th,8th,12th and 16th hour.[Conclusion] Compared with Chi pear and Dangshan pear,the pollens from Yali pear had stronger germination abilities and longer pollen tubes.With Yali pear tree as pollinizer,the yield of pear could be enhanced." @default.
