石棉县黄果柑生物学特性调查与差异株系比较

Biological Characteristics Survey and the Differences Compare in Strains of Huangguogan in Shimian

通过对四川省雅安市石棉县黄果柑变异株系和部分生物学特性的调查及果实品质分析,比较分析了主要相关生物学特性和果实品质之间的相关性。结果表明:黄果柑在果型上分为大果型和小果型,大果型又明显表现为凸蒂与平蒂2种果形,平蒂大果型产量高,可滴定酸含量低,维生素C及蛋白质含量高,品质综合表现好;同时,平蒂大果型树体开张,枝梢生长势较强,发育充实,叶片叶绿素含量较高,可作为黄果柑优质高产株系的树体评价依据。

Based on the investigations of different strains and biological characteristics, analysed on quality of Huangguogan in Shimian. The results showed that, the fruit size classified as big-sized and small-sized. On the other hand, the big-sized fruit shape menifested ＇flat fruit-base＇ and ＇convex fruit-base＇. The big-sized fruits which had ＇flat fruit-base＇ type showed the higher yield, vitamin C and protein content,lower acid content. It was the best type in Huangguogan. At the same time, the flat fruit-base of big-sized fruits branches were opening, the branch grew well, the leaves had high chlorophyll content. All of those could provided Huangguogan a basis for the high yield and good quality.
