摘 要:
在马尾松苗木生长期,用浓度为500μg·g^-1、1 000μg·g^-1、1 500μg·g^-1、2 000μg·g^-1多效唑进行喷施处理。结果表明,低浓度多效唑对马尾松苗木影响不大,高浓度多效唑对其影响极为显著。1 000-1 500μg·g^-1浓度多效唑可有效地提高马尾松的苗木质量,提高苗木抗寒能力和造林成活率。[著者文摘]

Abstract:
Paclobutrazol（ PP333 ） was sprayed upon Pinus massomana seedlings during their height growthperiod with various concentrations of 500 μg·g^-1, 1 000 μg·g^-1, 1 500 μg·g^-1 and 2 000μg·g^-1. Theresults showed that PP333 at low concentrations had little influence on the seedlings, but PP333 at high con-centrations had a significant infuence on them without any damage. PP333 at concentration of 1 000- 1 500μg·g^-1 could raise the quality of the seedlings and increase the cold resistance of seedlings and increase the survival rate after afforestation.[著者文摘]
