    摘要:

    将绿宝苹果分别授以首红、大红荣、摩力士、红富士、嘎啦和格力佛的花粉,以自然授粉为对照,分析不同品种授粉条件下绿宝苹果主要营养品质差异。结果表明,不同品种授粉后,绿宝苹果果实中的总糖、VC、黄酮、蛋白质、灰分及多酚含量相互间差异均达到显著或极显著水平;共筛选出3个主成分,累积方差贡献率为85.072%。综合各指标测定结果,并结合隶属函数及主成分分析认为,授粉品种不同,可影响绿宝苹果的营养品质;绿宝苹果营养品质从高到低依次为:红富士、大红荣、摩力士、首红、嘎啦、自然、格力佛的授粉果。

    Abstract:

    The differences of the main nutrient quality of bramley apples under different pollination conditions respectively with the pollen of First red, Dahongrong, MOLEX, Red Fuji, Gala and Grieve were analyzed in this experiment, and the natural pollination was used as control. The results showed that the contents of total sugar, VC, flavonoids, protein, ash and polyphenols among bramley apples with different pollination varieties reached significant or extremely significant levels; three principal components be selected in this experiments, and the cumulative percent of that three principal components reached 85.072% respectively. It was considered that pollination varieties could affect the nutritional quality of bramley apple based on the results of each index, combined with membership function and principal component analysis; the nutritional quality of tested‘Bramley’apples be ranked from high to low were Red Fuji, Dahongrong, MOLEX, First red, Gala, natural and Grieve.
