摘要
调查分析东川、元江和元阳3个干热河谷居群的牛角瓜结实等特征。结果表明,1元阳居群的牛角瓜单株结实量、单位冠幅结实量和单枝结实量最高,分别为102.4个/株、35.1个/m2和34.6个/枝,且3个居群间这3个指标差异极显著;2居群内单株、单位冠幅和单枝结实量3个指标差异极显著;3各居群的单株结实量与单枝结实量、单位冠幅结实量和分枝相关性状间呈线性相关。元阳是牛角瓜人工栽培的首选区域,通过对结实量大的优良单株进行选育,可极大地提高其果实产量。
Fruiting characteristics of three Calotropis gigantea populations were investigated in three Arid-hot Valley in Dongchuan District,Yuanjiang and Yuanyang County. The results showed that（1）There were the maximum fruiting yields of individual shrub（IS）,unit crown（UC） and single branch（SB） of the Yuanyang population with 102. 4 fruit/IS,35. 1 fruit/UC and 34. 6 fruit. /SB,respectively,which presented significant differences of these three mentioned parameters in the three populations;（2） Within the population,aforementioned three parameters also had significant differences;（3） There were linear correlation between the IP fruiting number with fruiting yield of the SB,UC and branching related characters. Yuanyang was the first optimal region of C. gigantea artificial cultivation; it could greatly enhance fruiting yield via selecting productive ruit IS acting as breeding materials.
