摘要 地被石竹嫩枝扦插快速生根的研究表明:选用成熟度较高的地被石竹带顶芽茎段浸醮200mg/LIBA+5mg/L间苯三酚溶液后,扦插于蛭石:河沙为2∶1的基质上,在地温20℃、气温25℃、相对湿度90%的条件下培养,6d后形成完整的根,生根成活率可达93.8%,培育60d后可用于建植观赏草坪。 Study of the fast_striking of Dianthue plumarius by micro_cuttage showed that using IBA 200mg/L+Phlorogucinol solution 5mg/L to soak fairly matured stems of Dianthue plumarius with top sprouts, cutting them in the base material of vermiculite and riversand in the ratio of 2 to 1,and culturing them under the conditions of soil temperature 20℃,air temperature 25℃ and relative humidity 90%,completed roots would form in 6 days and the striking survival rate was 93.8%.After 60 more days of culture,the roots could be transferred to ornamental lawns to grow.
