阿月浑子栽培品种生长及结实生物学特性研究

对来自美国和新疆的6个阿月浑子(Pistacia vera L．)品种的生长及结实生物学特性进行了研究。分析结果表明：Kerman和26—18^#品种嫁接后3年开花结实。品种与50年生黄连木亲和力较高，嫁接成活侏率和成活穗率达70％～100％，但品种在5月20日后有“回芽”现象。枝叶生长呈S型曲线，叶面积指数(LAI)平均达3．98。Kerman品种每个接穗3年后产果穗最高达31个，坚果和核仁发育正常，每个果穗上具坚果88．5～116个。单果重0．81～1．89g，出核率和出仁率分别为54．32％～55．0％和48．08％～59．09％。

Studies on Biological Features of Growth and Fruiting from Pistachios Cultivars

The biological features on growth and fruiting of six pistachio cultivars from the US and Xinjiang of China were studied. Results show that Kerman and 26-18~# cultivars can bear nuts after grafted three-year old at Taian, Shandong. Affinity is vary strong between Pistacia vera and Pistacia chinensis about fifty-year old, survival tree rate and survival scion rate of pistachio cultivars grafted are 70%-100%, but there are dying buds (shoots) after 20 May grafted. Growth rhythm appears S-type to leaf and shoot of pistachio cultivars, leaf area index (LAI) mean is 3.98. Three-year old after grafting, there are thirty-one spikes on maximum growing scion and 88.5-116 nuts on each spike, and nuts and kernels develop very well. Each fruit wt. is about 0.81-1.89 g, stone/fruit and kernel/stone are 54.3%-55.0% and 48.1%-59.1%,respectively. Biological features of growth and fruiting on pistachio cultivars are discussed in this paper.
