Abstract: Seedings of Datura stramonium L. var.tatula Torrey were grown under different light intensity(high light intensity, low light intensity)and different tempreture(high temperature, low temperature), and hand-sections were made to determin the influence that the two environmental conditions would have on the distribution characteristics and morphogenesis of purple idioblasts. The results showed that compare with the control group(normal condition), the color of purple idioblasts were observed deepened,and the transparency dropped and the gap between the idioblasts were smaller under high light intensity and high temperature, while the observations under other two low intensity conditions were on the contrary. In addition, the cross-section area, slitting length and quantity of the idioblast were significant increase under extreme high environmental conditions, however, under low light intensity, the results of the area and length were significant decrease, while the quantity was significant increase. But under low temperature,only the quantity of the idioblasts was significant increase, while other two indicators decreased but were not significant.

Key words: light intensity, temperature, idioblast, Datura stramonium L. var. tatula Torrey
