PP_(333)对荸荠试管苗增殖调控的研究

Effects of PP_(333) on Regulating the Proliferation of Eleocharis Tuvberosa in Vitro

在增殖培养基中添加0．25mg·L^-1-10mg·L^-1PP333能有效调控荸荠试管苗的形态发生能力，提高增殖系数，减少繁殖代数。培养壮苗后，一次性供试生根苗多，缩小了试管苗生长差异，提高了试管苗炼苗的成活率。

0.25 mg· L^-1 -1.0 mg · L^-1 of PP333 added into the proliferous medium could regulate the morphgenesis of the test - tube seedlings of Eleocharis tuvberosa, increase proliferous coefficient and decrease the frequency of sub - culture. The seedlings were strong and grew in step, so the survival rate was high after the seedlings were transplanted into the soil.
