Gene R1000 and R1000(PTVK85)were transformed to Popelys tomentosa,and their clones were achieved. After the vitro plantlets of the clones weretransplanted to field, their cutting experiment,growth measurement and morphological observation were carried out. The clones whose rooting rates wereimproved significantly accounted for 69.2%of the total tested clones. Of these clones,only 44.4% were observed neither to reduce their productivity nor tochange their morpgological characters. For the rest of the clones, the heightgrowth of one year-old cutting plants decreased about 30%.The total dryweight of stems, branches and leaves was 50% lower.There was a larger change in leaf morphological characters.The branch angles was narrow and thegrowth increment of branch was higher.Therefore,their economic values fortimber production were reduced.Besides,the plants of these clones appearedto have more buds and relatively higher net leaf weight.
