The leaf shape indexes of transgenic and control seedlings increase lightly when the IAA treatment concentrations are in two regions of 0~0.01mmolL^(-1) and 1.0~10.0mmolL^(-1) respectively, while LSIs decrease when IAA concentrations are between 0.01mmolL^(-1) and 1.0mmolL^(-1) this implies the depression effect on the growth in longitudinal is greater than that in transversal for both transgenic and control mesophyllous cells.

激素浓度在0~0.01mmolL^(-1)和1.0~10.0mmolL^(-1)两个区域时,转化株和非转化株的叶形指数略有增加,而在0.01~1.0mmolL^(-1)范围内,两者的叶形指数均呈下降趋势,表明IAA在此浓度范围内,叶肉细胞沿主叶脉方向的纵向生长受到的抑制强于横向生长所受到的抑制。

These suggest that the xenocrysts were captured by the enclave magma from the host magma. On diagram of total alkali vs. SiO〓(Middlemost, 1994), most samples of the host rocks plot within the area of diorite, the samples of the quenched margin plot within the area of gabbro-diorite and the samples of the enclave plot within the area of diorite.

General analysis indicates that Myriophyllum spicatum L.Panicle shape of the absorption of chromium Cr6 + concentration and treatment exist between the concentration of significant positive correlation with Myriophyllum spicatum L.can pollute the environment in better enrichment of chromium, the background environment The higher concentration levels of heavy metals, plant accumulation of heavy metals in higher concentration levels, the application of plant technology for the repair of heavy metal pollution on the environment to provide a scientific basis on Myriophyllum spicatum L. of heavy metal pollution of wetland restoration has great potential.

综合分析表明,在一定范围内,穗状狐尾藻对铬Cr6+的吸收富集含量随处理浓度升高而增大,说明穗状狐尾藻在污染环境中能较好地富集重金属铬,从而得出在一定范围内,环境背景中重金属含量水平越高植物富集重金属的含量水平也越高的结论,这就为应用植物技术修复重金属对环境造成的污染提供科学依据,而穗状狐尾藻对湿地重金属污染具有较大的修复潜力。
