Experiment on vitro propagation of Daemonorops margaritae by sucker as explant showed that high concentration of 6BA and multiple hormones combination could promote cluster induction.

Primary germinating induction culture,embryo seedlings elongation culture and rooting culture were carried out.

bournei is present, its main regenerate type is by means of seed, the population age structure appears as “pyramid” pattern so that it enables the population to have a stable increase; sprouting is also the type of regeneration but is of weak capacity, with the net reproduction rate R o <1.

Experiment on 4 reproduction methods just as adult cutting, seed germination,sprouting and young cutting showed that under natural conditions, the former two method could not success; sprouting had higher sucess rate; young sprouting had possibility be successed, which also needed to be studied.

For a quick method to controlling the soft sandstone areas,the author investigated the sprouting capacity of newly planted Hippophae rhamnoides forest in Zhungar township through the method of sample plot.

1mg/L,on which the bud induction rate was 96% and the proliferation coefficient was 2.

Several factors on affecting rabbiteye blueberry bud induction, differentiation and plant regeneration were studied.

It is found in this experiment that the most suitable cultural media for bud induction is MS+IBA0.
