Abstract:
Taking Zizyphus jujuha Mill.cv.‘Jing 39’ and Zizyphus jujuha Mill.cv.‘Langjiayuanzao’ as test materials，the effect of spraying ABA (abscisic acid) at different time and spraying three times on their leaf and fruit skin stomata were investigated.The results showed that：stomata density of Zizyphus jujuha Mill.cv.‘Jing 39’ decreased gradually with the increase of ABA concentration and decreased significantly in third time，and stomata density of Zizyphus jujuha Mill.cv.‘Langjiayuanzao’ in the third time was higher than that in the second time；At the same time，fruit stomata density of Zizyphus jujuha Mill.cv.‘Jing 39’ decreased gradually，which was a significant difference from contrast，and fruit stomata density of Zizyphus jujuha Mill.cv.‘Langjiayuanzao’ did not change obviously.After spraying ABA，leaf stomata density and peel stomata open-degree of Zizyphus jujuha Mill.cv.‘Jing 39’ showed significant difference from control；however，skin stomata density of Zizyphus jujuha Mill.cv.‘Jing 39’ showed no significant difference at different time.The stomata open-degree of Zizyphus jujuha Mill.cv.‘Langjiayuanzao’ tended to be significantly different from control，and fruit peel and leaf stomata density showed no significant difference.Fruit stomata open-degree of Zizyphus jujuha Mill.cv.‘Jing 39’ increased with the increasing ABA concentration gradually and fruit stomata open-degree of the third time was significantly different from that of the other two times；fruit stomata open-degree of Zizyphus jujuha Mill.cv.‘Langjiayuanzao’ showed no significant difference from control.The results of research could play an important role in guiding the jujube production.
