栝楼雌雄植株激素和多胺含量的比较 总被引:2,自引:0,他引:2
在栝楼生长发育各阶段,采用高效液相色谱技术分别对雌雄植株叶片内源激素及多胺含量进行分析。结果表明,吲哚乙酸(IAA)含量在所测定的生长发育期,雌株始终高于雄株,而脱落酸(ABA)含量雌株始终低于雄株;玉米素核苷(ZR)和赤霉素(GA1/3)含量在营养生长期雄株高于雌株,雄株进入生殖生长阶段后迅速下降,而雌株继续保持上升趋势,直至雌株进入生殖生长期后才迅速下降。雌株叶片中亚精胺(Spd)含量极显著高于雄株;精胺(Spm)含量在营养生长期雄株显著高于雌株,而在雌株进入生殖生长后雌雄株间差异不显著;腐胺(Put)含量在营养生长期雄株显著高于雌株,而在雌株进入生殖生长后雌株显著高于雄株。试验结果表明:高含量的IAA和Spd有利于栝楼雌花发育,而高含量的Put和Spm有利于雄花发育。当雌雄花盛开后,多胺均呈下降趋势,Put和Spm在雌雄株间含量差异越来越小。 相似文献

The leaf surfaces of Dianthus caryophyllus plants cultured in vitro in either airtight or ventilated vessels were examined using scanning electron microscopy (SEM). The resultant hyperhydrated, non-hyperhydrated and acclimatized plants were compared for stomatal density, cuticular wax development and stomatal function. The leaf surfaces of in vitro cultured plants were basically the same as those of acclimatized plants but less wax deposition was observed on their leaves. Stomata were found both open or closed after transfer of plants ex vitro. However, stomata of in vitro leaves grown in ventilated culture vessels were more functional than plants grown in other conditions. Acclimatized plants had a normal leaf epidermal surface, and were wholly covered with waxes; their stomatal density being similar to that of highly ventilated plants but lower than that of less ventilated plants. Leaves of plants grown in airtight culture vessels or under a low number of air exchanges per hour had less waxes than plants grown at a higher number of air exchanges per hour or than acclimatized plants. In contrast, hyperhydrated plants had abnormal, malformed stomata and no wax deposition was detected. The adaxial surface of non-hyperhydrated leaves seemed more normal than the abaxial, especially in the most ventilated vessels, and this may be due to the former receiving more light and so developing in a more favourable microenvironment. 相似文献

Survey on the wild genetic resources of hardy kiwifruit (Actinidia arguta) in Japan was conducted to determine the ploidy variation and its geographic distribution. Among the 127 wild plants collected from different geographic locations, 15 plants were diploid, 87 were tetraploid, and 22 were hexaploid. Additionally, 2 plants were heptaploid and one plant was octaploid. The tetraploid plants were distributed all over the country, whereas the diploid and hexaploid plants were geographically localized, in the warm Pacific hill areas of the south western part and in the deep-snow region of the mid-northern part of Honshu, respectively. The diploid plants could be clearly distinguished from other plants with ploidy variation by the morphological characteristics of the leaf and fruit. Hexaploid plants showed a relatively larger L/D ratio of the leaf blade, a greenish petiole, and pubescence on the petiole and lower leaf vein, whereas the tetraploid plants exhibited a reddish petiole and callose hairs on the vein of the lower leaf surface. Fruit shape of the tetraploid plants varied largely, from round to ellipsoidal, whereas that of the hexaploid plants was mostly ellipsoidal. These results indicate that the hexaploid plants of A. arguta as well as the diploid and tetraploid ones, naturally grow in a certain size of population in the restricted region of Japan. 相似文献
