摘要
紫花芒果的果实生长呈双Ｓ型，分为四个发育阶段，即初始有限生长期（０期）、第一迅速生长期（Ⅰ期）、缓慢生长期（Ⅱ期）和第二迅速生长与成熟期（Ⅲ期）。０期长短与花开放日期有关。其余各期的持续时间分别是３９．７和４９ｄ。Ⅰ期主要是果实大小增长，果长达到成熟时的８８．０％。干物质主要在Ⅲ期累积。纤维质的内果皮（种核）在Ⅱ期硬化，落果主要在谢花后５周内，以２周内最多。紫花芒果有熟前落果现象。果实发育期９５～１３８ｄ。
The pattern of fruit growth in the mango cv.Zihua(Mangigera indica L.)was doublesigmoid.There were four periods of fruit development,namely,a period of initiallinuted growth(Stage 0),a period of rapid increase(Stage Ⅰ),a period of delayedincrease(Stage Ⅱ),and a second period of rapid increase and maturity(Stage Ⅲ).The duration of Stage 0 was correlated with the date of anthesis.The durationof other stages were 39,7,and 49 days,respectively.Size increases occurred mainlyduring Stage Ⅰ,attaining 88.0% of the length at maturity, while dry matters mostlyaccumulated in Stage Ⅲ.The fibrous stony pericarp hardened in Stage Ⅱ.Fruitsabscisai in about five weeks after flower shedding, the main wave being in the first twoweeks. Premature drop of fruit was also a problem in the mango cv.Zihua.Fruitsmatured in 95～138 days.Some factors affecting fruit growth and abscission werediscussed.
