不同落果特性花生品种荚果性状及果壳强度的研究

The Research on Pod Traits and Shell Strength of Peanut Varieties with Different Fruit Drop Characteristics

在田间试验条件下,系统研究了不同落果特性花生品种的荚果性状、果壳强度、果壳结构及结构物质含量。结果表明:不易落果品种潍花13号(W13)和潍花32号(W32)果壳厚度和果腰直径显著高于易落果品种潍花6号(W6)和潍花11号(W11);不同成熟度和含水量荚果的果壳破碎强度、果壳的中果皮和内果皮厚度及子房柄与荚果连接处厚度、果壳中结构物质含量均显著高于易落果品种;同类型品种间各项指标差异不明显。

The pod characters, nutshell strength, nutshell structure and content of structural substances of peanut varieties with different fruit drop characteristics were systematically studied under field conditions. The results showed that the thickness of fruit shells and diameter of fruit waist of the uneasily shedding varieties Weihua13 (W13) and Weihua32 (W32) were significantly higher than those of the easily shedding varietiesWeihua6 (W6) and Weihua11 (W11). The fracture strength of pods with different maturity and moisture content, the thickness of mesocarp and endocarp of fruit shell, the thickness of the joint between ovary stalk and pod, and the content of structural substances in shell were significantly higher than those of the easily shedding varieties. There was no significant difference in each index among the same type of varieties.
