Observation of the Stomatal Behavior of Test-tube Plantlet of Transgenic Male Abortive Populus tomentosa Carr
摘要
Abstract
[Objective] To study the causes of abnormal stomatal behavior of test-tube plantlet. [ Method ] The change of stomatal density, stomatal size, the daily variation of stomatal aperture and stomatal open percentage of the leaves' lower epidermis of test-tube plantlets and 10-year-old plants of transgenic male abortive Populus tomentosa Carr were observed and compared in this paper by using nail polish method. [Result] The stomatal density of test-tube plantlets was less than that of the 10-year-old plant; test-tube plantlets' stomata was obviously larger than that of the 10-year-old plant; the stomatal aperture of test-tube plantlets showed wave crest, and the two peaks appeared at 9:00 and 15 :00,10-year-old plant had steady curve without evident fluctuation,and the stomatal aperture in test-tube plantlets was greater than that in the 10-year-old plant; stomatal open percentage reached 100% in test-tube plantlets during a day,a bimodal curve change was observed in stomatal open percentage of the 10-year-old plant. [Conclusion] Stomatal behavior were different between the test-tube plantlets and the 10-year-old plant of transgenic male abortive Populus tomentosa Carr.关键词
