Anatomical Studies Of Polygonatum Mill.

Lily Polygonatum sibiricum Red genera(Polygonatum Mill.) system establishment in Miller1754 has published more than 60 species, s in the north temperate zone, mainly distributed in the Himalayas to Japan. Polygonatum sibiricum Red in China belong to resource reserves is big, rich plant resources, including Polygonatum sibiricum Red, the most abundant resources of Polygonatum odoratum(Mill.) Druce. Plants of the genus Polygonatum sibiricum Red has good application value, if the application is proper, will expand its medicinal, edible and ornamental and cosmetic applications, would bring huge economic benefits. Polygonatum sibiricum Red plant not only has important application in modern medicine pharmacological activities, for the treatment of various diseases have a positive effect.Polygonatum involucratum Maxim and Polygonatum odoratum(Mill.) Druce rhizome, rhizoma polygonati have tonifying qi, runfei, strong gluten JianGu efficacy; Polygonatum odoratum(Mill.) Druce can nourish dry, except vexed enfold effect, so the two crude drugs of plant-based sources are often confused.In the field of study in China, the yellow fine leaf anatomy research involves the little, mostly in the resource value and ecological value, etc.At present our country about Polygonatum involucratum Maxim anatomic study is relatively small, in this paper, the jilin agricultural university in July 2014, picking the botanical garden, the plants of the genus Polygonatum involucratum Maxim and Polygonatum odoratum(Mill.) Druce root leaf anatomical structure of the comparative analysis, by means of microscopic observation of the structure surface is analyzed, designed to divide between the species of the plant and to provide the anatomical support. On yellow liquor and Polygonatum odoratum(Mill.) Druce morphological anatomy structure is studied, from the roots of the plant leaf structure aspects, for better overall system provides the theoretical foundation research solomonseal genus.In this paper, the research results show that :1. Polygonatum involucratum Maxim and Polygonatum odoratum(Mill.) Druce root anatomical structure, according to the epidermis, cortex and vascular cylinder main volume and catheter group very sad.The structure which is similar, have affinity, but slightly thick Polygonatum odoratum(Mill.) Druce root epidermal cells than Polygonatum odoratum(Mill.) Druce.Vessel diameter compared with Polygonatum odoratum(Mill.) Druce tube diameter is bigger. carved Polygonatum odoratum(Mill.) Druce root diameter is yellow significantly larger, with significant difference.Same results also show that the thickness of the Polygonatum odoratum(Mill.) Druce root cortex thickness is bigger, more than 2 times the Polygonatum involucratum Maxim.These results indicate that the Polygonatum odoratum(Mill.) Druce is yellow fine development better, has the stronger ability to adapt to the environment.2. Polygonatum involucratum Maxim and Polygonatum odoratum(Mill.) Druce, according to the anatomical structure of Polygonatum odoratum(Mill.) Druce stem yellow fine and Polygonatum odoratum(Mill.) Druce stalk basic composition similar, but the stem tube diameter, length, width, and significant differences stem diameter, etc. carved Polygonatum odoratum(Mill.) Druce stem epidermal cells with yellow thicker, but the stem cortex thickness and diameter and tube length than width solomonseal bigger, better description of Polygonatum odoratum(Mill.) Druce channel capacity.3 The ratio of cortex for Polygonatum involucratum Maxim stem is relatively small, and cortex parenchyma cells are seen in obvious inclusions,which is the result of plant adaptive evolution; Polygonatum involucratum Maxim stalk lignification degree is more higher and the mechanical organization is more developed than Polygonatum odoratum(Mill.) Druce, showing its stem will have a better ability of mechanical support; Visible catheter in Polygonatum involucratum Maxim stems from the perspective of the evolution is short and thick.4. The carved Polygonatum odoratum(Mill.) Druce and yellow leaf epidermal cells styles is given priority to with type G, anticlinal walls that both have homology. Polygonatum involucratum Maxim leaf main vein vascular bundle lignification degree is higher than the Polygonatum odoratum(Mill.) Druce, but would be a big brittle leaf. Polygonatum odoratum(Mill.) Druce piece relatively developed mechanical organization strength, more adaptive to habitat change. In addition to all this Polygonatum involucratum Maxim has aerenchyma and facilitate for gas transmission, and Polygonatum odoratum(Mill.) Druce leaf has obvious secretory cavity.
