寒地植物冬季组织器官结构对滞尘量的影响

Effects of organ structure in winter on detain dust quantity of plants in cold region

采用显微观测法结合冬态滞尘量测定分析法,研究了24种寒地植物的冬态滞尘量与组织器官结构的相关性。结果表明,具有较好冬态滞尘能力的寒地植物包括:紫丁香、红皮云杉、银中杨等,冬态寒地植物的滞尘量与植物宿存组织及其特征、分枝类型等因子密切相关。

Correlation between detain dust ability of plants in cold region and its organ structure were studied based on microscopic observation method and determination method of dust in winter. The result showed that The cold plants with good detain dust capac!ty in winter condition include： Syringa oblata, Picea koraiensis Nakai, Populus alba x P. berolinensis and so on. The detain dust capacity in cold land is closely related to plant tissue and its characteristics, branch type.
