椰子果水化育苗及生理特征初步研究

Preliminary Study on Coconut Water and Physiological Characteristics of Seedling

摘要: 目的：摸索出一套适于椰子繁育的方法或途径，加快传统育苗技术的革新，促进工厂化育苗技术的发展。本研究以10个月的海南高种椰子、“文椰2号”椰子、“文椰3号”椰子、“文椰4号”椰子4个品种的果实为材料，以时间为轴线，分别观测对照和水化处理两组4个品种的胚芽萌发、胚根生长、侧根生长量和幼苗生长量。结果表明，水化育苗处理后，椰子的胚芽萌发、胚根生长、侧根生长量和幼苗生长量等方面，均显著高于对照处理的幼苗。水化育苗技术与传统育苗技术相比，可以使椰子育苗的萌发提前，缩短育苗时间等，水化育苗最好的品种是“文椰4号”。水化育苗技术适于规模大、集成要求高的种苗繁育，可以有效的缩短育苗 周期并节约成本。

Abstract: Aims: To explore a set of methods for the breeding of coconut, accelerate the innovation of tradi-tional breeding technology, and promote the development of breeding technology in factory. Four varieties of coconut aged ten months were used as the material of this experiment. The fruits of Hainan high coconut, “Wenye 2”, “Wenye 3” and “Wenye 4” coconut were used as the experimental material. Based on a time axis, we measured and compared the growth of radicle, lateral root and seedling as well as the embryo germination of four varieties in two groups. The results showed that the hydration breeding technology is better than the traditional breeding techniques, especially in terms of embryo germination, radicle growth, lateral root growth and seedling growth which significantly increase. Hydration seedling technique can shorten the breeding time, and advance the germinating of embryo. “Wenye 4” is the best variety for hydration seedling. As for seedling propagation which proceeds great scale or highly integrates, it can shorten the breeding cycle and be cost-effective.
