| 摘 要： | 目的]为了研究不同品种和密度对田菁籽粒产量及其相关性状的影响。方法]比较田菁在不同密度下植株的株高、茎粗、地上部鲜重、结荚数、结荚枝数、秕粒率等指标。结果]各密度下同一品种田菁生长性状、结荚特征具有明显差异,籽粒产量虽变化不大,但以7.5万株/hm2密度下秕粒率最低,籽粒更饱满;不同田菁品种间籽粒产量差异较大。结论]通过选育品种、合理调节田菁种植密度等措施,可获得品质更高的田菁籽粒,并实现高产,为黄三角地区田菁胶的工业化生产提供丰富的原料。

| Abstract: | Objective ] The research aimed to study the effects of Sesbania varieties and planting density on seed yields and correlated charac- ters. Method ] The plant height, stem diameter, shoot fresh weight, pods numbers, pod branch numbers and immatured grain rate at different planting densities were analyzed. Result] There were significant differences on plant growth for the same species at different planting densi- ties. Although planting density had no obvious influence on seed yields, immatnred grain rate was the lowest at the planting density 75 000 plant/bin2, the seed yields were significant in different varieties. Conclusion] The higher seed yields and better quality of Sesbania could be obtained by breeding new varieties and controlling planting density rationally in order to provide the abundance resource for the Sesbania gum industrialized production in the Yellow River Delta. |
