| 摘 要： | 目的]研究水培和土培碗莲的生长特性。方法]以碗莲品种＇红霞＇为试验材料,设置了水培和土培2个处理,测定其光合指标、叶绿素含量和根系活力,观察叶片组织结构和气孔特性。结果]水培碗莲与土培碗莲的叶片生理指标没有差异;水培碗莲叶片气孔大且数目多,同时,栅栏组织与海绵组织厚度比值小,叶片组织结构疏松;水培碗莲的根系活力提早达到峰值,然后下降,而土培碗莲根系活力持续增长,生长旺盛。结论]水培碗莲可以快速地很好地适应水培环境,但是,进入衰老期较快,生长周期较短。

| Abstract: | Objective] The experiment aimed to study the growth characteristics of hydroponic bowl lotus. Method] The lotus variety Hongxia was chosen as the experimental material. Two treatments, hydroponics and soil culture were set to measure their photosynthetic indices, chlorophyll content and root vigor, and to observe their leaf tissue structure and stomatal characteristics. Result] The findings indicated that there are no differences in the leaf physiological indices between bowl lotus under hydroponics and soil culture, while the leaf stomata of hydroponic bowl lotus is bigger and its amount is larger than that of soil-culture bowl lotus. At the same time, the ratio of the palisade tissue thickness to spongy tissue thickness is small,and its leaf tissue structure is loose. The root vigor of hydroponic bowl lotus reached its summit earlier, then began to drop. Whereas, the root activity of soil-culture lotus sustained increasing, with vigorous growth. Conclusion] Therefore, it indicated that hydroponic bowl lotus can adapt to the aquatic-culture environment well and quickly, meanwhile, it also enters into its aging period quickly and its growth cycle gets shorter. |
