Show model combines growth model, math model and VR technologies to design the proper object structure of each organ of virtual plant. First of all,research background, research content of virtual plant area and Virtual Reality technology are introduced. The concept of VR and research content of virtual plant are defined. Secondly, we analyze math model of virtual plant, including Bezier curve, NURBS curved surface, fractal system, L-system and Catenary curve. Thirdly, we give show model of virtual plant in detail. Finally, the design of the platform and growth model on XML script is introduced , and how to show the virtual plant in the platfrom is discussed too.

Obconica were always higher than that of P. vulgaris. In the experiments of medicament treatment Membership Function was introduced to have a comprehensive evaluation on heat-resistance of P. obconica and P. vulgaris under five levels of fixed temperature. The results were as follows: P. obconica 30℃: The compages of SA 150 mg·L~(-1 and CaCl_21500 mg·L~(-1 can increase plant"s heat-resistance observably. 32℃: Using SA only 200 mg·L~(-1 can increase plant"s heat-resistance observably.34℃: The compages of SA 50mg·L~(-1 and CaCl_21500 mg·L~(-1 can increase plant"s heat-resistance observably.36℃: The compages of SA 50 mg·L~(-1 and CaCl_22000 mg·L~(-1 can increase plant"s heat-resistance observably.38℃: The compages of SA 150 mg·L~(-1 and CaCl_21000 mg·L~(-1 can increase plants heat-resistance observably.
