9种风传杂草种子的扩散能力及传播策略
Dispersal Ability and Spread Strategy of Nine Species of Weed Seeds
摘要
Abstract
[Objective] To study the dispersal ability and spread strategy of nine species of weed seeds.[Method] Nine species weeds were used as test materials to study the spread abilities(falling speed,horizontal dispersal distance)and their correlation with seed morphological structures.[Result] The falling speed of 9 species of weed seeds had significantly negative correlation with horizontal dispersal distance.The falling speed of Compositae seeds had a positive correlation with fruit length and fur length,while the falling speed of Gramineae seeds had a negative correlation with fruit length and fur length.The horizontal dispersal distance of Compositae seeds had a negative correlation with fruit length and fur length,while that of Gramineae seeds had a positive correlation with fruit length and fur length.These results indicated that the spread strategy of Gramineae seeds and Gramineae seeds were different.[Conclusion] The research can provide theoretical basis for understanding the dispersal mechanism of seeds and weed control.关键词
