摘要
高干、中干、低干开心形苹果树和自由纺锤形苹果树(对照)的研究结果表明,在初果期,对照及低干开心形树产量较高,分别比高干开心形树高20.9%和17.9%,其产量构成与公顷枝量呈正相关;在盛果期,高干和中干开心形树产量显著高于对照,分别比对照提高了17.4%和17.8%,其产量构成与树体枝轴长度呈正相关。果皮色素花色苷含量、果肉可溶性固形物含量(TSS)等指标在初果期不同树形处理无显著差异;在盛果期,高干和中干开心形树处理显著高于对照,果实综合品质优良。
The result of the treatments with high,middle and low trunks open-centre trees and free spindle trees,as the control,showed that： At early fruit period,the yields of the control trees and low trunk trees were higher than those of high trunk treatment by 20.9% and 17.9% respectively,and the yields of four treatments were positive correlated with per hectare branch quantity.However,at full fruit period,the yields of high trunk and middle trunk trees were significantly higher than that of the control tree by 46.8% and 46.7%,and the yields of four treatments were positively correlated with the fruiting branch length of trees.The contents of pigmented anthocyanin in peel and TSS in flesh of different treatments were no significantly different at early fruit period,but at full fruit period,the contents of anthocyanin and TSS were significantly higher than that of the control trees.The comprehensive quality of middle and high trunk open-centre trees was excellent at full fruit period.
