摘要
为探明不同梨品种对'苹果梨'果实的花粉直感效应,作者选用'红早酥''绿早酥''绿宝石''玉露香'4个不同品种作为授粉树,以生长良好、40年生以上的'苹果梨'作为授粉对象进行人工授粉试验,对其坐果率、果实外观和内在品质等指标进行综合分析与评价.结果表明,各授粉品种对'苹果梨'果实的坐果率、外观和内在品质及收种率影响显著,表现出明显的花粉直感效应.以'绿早酥'授粉的'苹果梨'坐果率最高,但单果重最小;以'绿宝石'授粉的'苹果梨'坐果率适中,收种率最低,但单果重、果型指数和果肉硬度最大,可溶性固形物、可溶性糖、石细胞含量最高;以'红早酥'授粉的'苹果梨'坐果率、收种率适中,维生素C含量最高,但可滴定酸和可溶性固形物含量最低;以'玉露香'授粉的'苹果梨'坐果率最低,收种率适中,可滴定酸含量最高,果型指数和果肉硬度最小.综合比较,'绿宝石'梨较适合作为'苹果梨'的授粉品种.
Abstract
In order to investigate the xenia effect of different pear varieties on the fruit of'Apple-pear',the author selected four different varieties of'Hongzaosu''Lvzaosu''Lvbaoshi''Yuluxiang'as pollination trees,and conducted artificial pollination experiments on'Apple-pear'with good growth and over 40 years of age as pollination objects.The comprehensive analysis and evaluation of their fruit setting rate,fruit appearance,and internal quality were conducted.The results showed that each pollination variety had a significant impact on the fruit setting rate,appearance,internal quality,and seed collection rate of'Apple-pear'fruits,exhibiting a clear xenia effect.The'Apple-pear'pollinated with'Lvzaosu'has the highest fruit setting rate,but the single fruit weight was the smallest;The'Apple-pear'pollinated with'Lvbaoshi'has a moderate fruit setting rate and the lowest seed collection rate,but the single fruit weight,fruit type index,and flesh hardness were the highest,and the content of soluble solids,soluble sugars,and stone cells were the highest;The'Apple-pear'pollinated with'Hongzaosu'has moderate fruit setting and seed collection rates,the highest vitamin C content,but the lowest titratable acid and soluble solids content;The'Apple-pear'pollinated with'Yuluxiang'has the lowest fruit setting rate,moderate seed collection rate,the highest titratable acid content,and the lowest fruit type index and flesh hardness.Overall,'Lvbaoshi'pear was more suitable as a pollination variety for'Apple-pear'.
