- 摘要:
- 以‘京枣39’（Zizyphus jujuha Mill.cv.‘Jing 39’）和‘郎家园枣’（Zizyphus jujuha Mill.cv.‘Langjiayuanzao’）为试材，研究了喷施脱落酸（ABA）后不同时间和在喷施3次ABA后对不同裂果性枣叶片和果实表面气孔的影响。结果表明：ABA处理时，随着喷施次数的增加，‘京枣39’品种叶片气孔密度逐渐降低，到第3次喷施后显著降低，而‘郎家园枣’在第3次喷施后气孔密度较第2次却有所回升；同时，‘京枣39’果实气孔密度逐渐降低，与对照有显著差异，而‘郎家园枣’果实气孔密度变化不明显。在ABA处理后不同时间，‘京枣39’叶片气孔密度、果皮气孔开度与对照处理有显著差异，果皮气孔密度无差异，‘郎家园枣’果皮气孔开度与对照处理有显著差异，果实和叶片气孔密度均无显著差异。‘京枣39’果实气孔开度随着喷施ABA次数的增加而增加，到第3次喷施后显著增加，而‘郎家园枣’果实气孔开度和对照比较无显著差异。该研究结果对于指导枣的生产具有重要意义。
- 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.
