查询词典 gradients

Either in the un-drought or drought plots with various gradients of species richness, both survival competition ability and growth competition ability of Sida rhombifolia, Mosla dianthera and Cassia mimosoides were the lowest.

Under consecutive irradiance and 14 h / 10 h light-darkness cycle, the effects of different gradients of irradiance on seed germination of Shorea wantianshuea, an endangered and rare species of dipterocarpaceae in Xishuangbanna, Yunnan Province, were studied. Also, the effects of different temperatures on seed germination and storage were examined. Neither consecutive irradiance treatments nor periodic ones could improve the germination percentage.
