7种阳生型多年生草本植物对水分胁迫的响应
Response of Seven Perennial Sun Herbaceous Plants to Water Stress
摘要
Abstract
[Objective] The study aimed to provide the reference basis for building the ecological garden with the low carbon type. [ Method] 7 perennial sun herbaceous plants including Dianthur plumarius, Sedum pallidum, Sedum aldum, Sedum spurium, Sisyrinchium angmtifolium, Sedum reflexum and Sedum lineare were screened to be used as the tested materials, 4 water gradients were set up to make for the water stress, and the drought resistance characteristics of 7 plants were studied on the water transpiration and photosynthesis characteristic. [ Result ] The diurnal variation of water consumption for 7 plants was single-peak type under the enough moisture condition, while the peak would reduce and the peak period could appear earlier or later with the aggravation of the water stress. The total diurnal water consumption of those plants was different, but it was the same with the order of water consumption in the high-peak period. Except S. Anguslifolium, the Fv/Fm value in the water stresses with different grades for the various plants has not obvious reduction or only had the reduction of less than 3.0% , showing that the serious water stress could cause a little damage to the photosynthesis of the various plants which were all drought-enduring plants. [ Conclusion] As long as meeting the water consumption during the peak periods, the growth demand and ornamental characteristics of 7 perennial sun herbaceous plants could be maintained basically.关键词
