| 摘 要： | 用分光光度法测定对比了野生和组培吊石苣苔叶绿素含量的日变化,以了解吊石苣苔光合生理,以便更好地引种栽培吊石苣苔.结果表明:野生吊石苣苔叶绿素a、叶绿素b及总叶绿素含量都高于组培吊石苣苔；野生吊石苣苔叶绿素a、叶绿素b及总叶绿素含量的高峰值都出现在14:00,组培吊石苣苔都出现在16:00;野生吊石苣苔叶绿素含量的日变化趋势是先升高后降低,组培吊石苣苔是先降低、再升高、然后再降低；野生吊石苣苔叶绿素a/b比值小于组培吊石苣苔.综上,野生吊石苣苔叶绿素含量高于组培吊石苣苔,捕捉光能以及光能转换能力比组培吊石苣苔强.组培吊石苣苔对环境变化的适应能力较野生植株弱,还需继续优化组培苗移栽条件.

| Abstract: | For the purpose of know photosynthesis physiology on Lysionotus pauiflorus.The day changing law about chlorophyll content between wild and tissue culture Lysionotus pauiflorus were researched by spectrophotography.The results showed that the content of chlorophyll a,chlorophyll b and chlorophyll(a+b)of wild Lysionotus pauiflorus were higher than tissue culture Lysionotus pauiflorus.The maximum content of chlorophyll a,chlorophyll b and chlorophyll(a+b)of wild Lysionotus pauiflorus was at 14:00 PM,and the ti... |
