翠冠梨果枝类型及坐果序位与产量和果实品质的关系

以翠冠梨为试材,探讨了不同果枝类型、坐果序位与产量、果实品质的关系。结果表明:翠冠梨长、中果枝结果总量超过短果枝,且长果枝果实可溶性固形物含量较高,中果枝果实果形较端正,修剪上应适量保留这两者结果,以提高产量,增进品质;不同坐果序位的产量分布及果实品质差异明显,第1至第3低序位果在产量上占有绝对优势,综合品质优于中、高位果,尤以第2低序位果所占产量比例最大、果形端正一致、可溶性固形物含量最高,疏果时应尽量加以保留。

Relationship between fruit-bearing branch type/position and yield/quality of Cuiguan pear

The relationship between the type of fruit-bearing branch and fruit position and the yield and quality of Cuiguan pear was studied.It was found that the total fruit yield on long or medium branches was more than that on short branches.The soluble solids content of the fruits born on long branches was higher than that in short branches,while the fruits form the medium branches had better shapes.Thus,proper pruning could improve the fruit yield and quality.Fruit position on a branch also significantly affected the yield and quality.The fruits on the first to the third positions tended to weigh more and have higher quality than the others.Especially,the second fruit on a branch had the highest yield,best shape and most soluble solids.Even though the weight of a single fruit positioned second did not significantly differ from the first and the third on a same branch,it would be prudent to keep the fruit born on the second position.
