花棒多分布在半干旱、干旱的沙区,由于其天然分布区内环境条件的差异较大,故在长期的系统发育过程中形成了与环境条件相适应的两个生态型。即多小叶花棒和元小叶花棒。但不同生态型花棒的生物、生态学特性如何,经济价值怎样,却尚未见报道。我们测定了两种花棒苗期的蒸腾强度,并研究了它们的蒸腾强度日进程、日蒸腾量,以及蒸腾强度与光照、气温、相对湿度等气象因子的关系,目的在于进一步深入研究花棒的不同生态型在生理、生态特性方面的差别。
The flower buds are mostly distributed in semi-arid and arid sandy areas. Due to the large differences in environmental conditions within their natural distribution areas, two ecotypes corresponding to environmental conditions have been formed in the long-term phylogenetic process. That is, multi-leaflets and leaflets flower stems. However, the biological and ecological characteristics of different ecotypes and how their economic value have not been reported yet. We measured the transpiration intensities of two species of seedlings at seedling stage and studied the relationship between the daily process of transpiration intensity, daily transpiration, and the meteorological factors such as transpiration intensity, light temperature, relative humidity and so on. The purpose is to further study Differences between different ecotypes in physiological and ecological characteristics.
