Objective To provide the morphological basis for identify exactly seeds of Gentiana macrophylla Pall, and Gentiana straminea Maxim. 目的为准确鉴别秦艽和麻花秦艽种子提供形态学依据。
Using the leaves of Gentiana macrophylla Pall, as explants, the embryogenic calli were induced and regenerated plants were produced. 本研究以大叶秦艽幼苗叶片为材料,对其进行了离体组织培养研究。
A portable photosynthesis system was used to study the photosynthetic characteristics of Gentiana macrophylla Pall, and G. dahurica Fisch. at the flowering stage. 运用光合作用测定系统,对野生秦艽(GentianamacrophyllaPall.)和小秦艽(G.dahuricaFisch.)的开花期的光合特性进行研究。
3, the methods of processing and store of Gentiana macrophylla Pall. 3,秦艽生药的产地加工及储藏方法初探。
The results showed that: ( 1) CO2 laser irradiation of lower dose ( 30s-60s) promoted seed germination, Improved content of total chlorophyll, chlorophyll a, chlorophyll b and soluble protein, and then promoted the seedling growth of Gentiana macrophylla Pall. 较低剂量(30秒~60秒)的CO2激光处理可以促进秦艽种子的萌发率和发芽势;提高幼苗叶子的总叶绿素、叶绿素a、叶绿素b含量和可溶性蛋白含量,促进秦艽幼苗生长。
( 2) Supplementary UV-B radiation had a little effects on growth but positive effects on quality of biennial Gentiana macrophylla Pall. 在生长季节,给二年生的秦艽补充适量UV-B辐射,发现增强UV-B辐射对秦艽的生长影响不大,而对其品质产生正效应。
