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.
