    摘要:

    在全面调查深圳市植物资源的基础上,选取了20多种具有较高观赏价值的本土野生植物进行采种繁育试验,经过2年多的观测记录,摸清了这些乡土树种的发芽时间、发芽率等规律,发芽率从4.45%~86.00%,发芽持续时问从13~140d不等,成功培育出乡土树种苗木15万株,提出了把握采播时间和高温浸种等提高发芽率的措施,为保护城市园林生物多样性做了有益的探索。

    Abstract:

    Based on field survey of plant resource in Shenzhen, more than 20 local wild plant species of high ornamental value were selected and their seeds were collected for testing. Through two years of observations, the regularity of sprouting time and sprouting rate, etc., were ascertained. Their germination rate differ from 4.45% to 86.00% and duration of sprouting is from 13 days to 140 days. This research was successful in cultivating 150 000 saplings and provided the method of improving germination rate by adjusting breeding time and hot water treatment, which made a contribution to the exploration for the biodiversity of urban landscape.
