不同整枝方式对樱桃番茄果实商品性、营养品质及产量的影响

Effects of different pruning patterns on fruit commodity,nutritional quality and yield of cherry tomato

以樱桃番茄‘香妃3号’为试验材料,设置单杆(T_(1))、双杆(T_(2))、三杆(T_(3))、四杆(T4)、五杆(T5)5种整枝方式,调查果实表型性状和生育期,测定其营养品质和最终产量,并结合主成分分析、方差分析等统计学方法,揭示整枝方式对樱桃番茄果实商品性、营养品质、生育期和产量的影响。结果表明:整枝方式对樱桃番茄商品性的影响显著,五杆整枝处理的商品性综合得分高于其他处理,其果实维生素C含量显著高于其他处理,蔗糖含量较其他处理均有不同程度的提高,产量最高且与单杆整枝差异显著,达5789.85 kg/667 m^(2)。说明五杆整枝更有利于樱桃番茄果实商品性的改善、营养品质成分的积累和产量的提高。

This study aims to research the influence of various pruning patterns to fruit commodity,nutritional quality,growth period and yield of cherry tomato.We selected Solanum lycopersicum cv.‘Xiangfei3’as the experimental material,set up five pruning patterns(T_(1),one-bar;T_(2),two-bar;T_(3),three-bar;T4,four-bar;T5,fivebar),investigated its phenotypic traits and growth period,measured its nutritional quality and yield,and used principal component analysis,analysis of variance and other statistical methods for data analysis.The results indicated that the effect of pruning patterns on the commodity of cherry tomato was significant,and the comprehensive score of commodity of five-bar pruning treatment was higher than the other treatments.The content of vitamin C in the five-bar pruning was significantly higher than the other treatments,and the sucrose content increased with different degrees compared with the other treatments.At the same time,the yield of fivebar pruning treatment was the highest(5789.85 kg/667 m^(2)),which was significantly different from that under the one-bar pruning treatment.It can be seen that five-bar pruning is more conducive to improve fruit commodity,accumulate nutritional quality ingredients and increase yield of cherry tomato.
