狭叶四照花果实性状变异分析

Multiple Fruit Characters Variation of Different Sources of Dendrobenthamia angustata

对分布于鄂西南的狭叶四照花果实测定果重、横径、纵径、果穗梗长、果形指数等指标,结果表明:(1)果实性状与果重的关联程度为果形指数>果实横径>果穗梗长>果实纵径;(2)产自利川市花板溪的果实性状综合评价最好.

The multiple fruit weight, multiple fruit diameter, multiple fruit length shape coefficient of Dendrobenthamia angustata in southwest Hubei Province were , stipe length and multiple fruit detemined. The results showed： （ 1 ） The relevance of other multiple fruit characters to multiple fruit weight is： multiple fruit shape coefficient 〉 multiple fruit diameter 〉 stipe length 〉 multiple fruit length ; （2） The synthetic evaluation of multiple fruit characters of Dendrobenthamia angustata in Huabanxi was ranked first.
