以黑心菊、矮牵牛、万寿菊、孔雀草、醉蝶、翠菊为试材,研究了樟子松枝叶浸提液对6种不同花卉的种子发芽的影响。结果表明:樟子松1年生枝浸提液对孔雀草、矮牵牛种子的发芽率无显著影响,对其它4种花卉种子的发芽率影响显著;3年生枝浸提液对黑心菊种子的发芽影响显著,其它花卉种子发芽率无显著影响;5年生枝浸提液对黑心菊、醉蝶、翠菊的发芽影响显著,对其它3种花卉种子的发芽率无影响;落叶浸提液对全部试材均有显著影响;宿存叶浸提液对万寿菊、醉蝶的发芽影响不显著,对其它4种花卉种子发芽有显著影响。
The effects of Pinus sylvestris var. Mongolica on seed germination of six different flowers were studied with black heart-shaped chrysanthemum, petunia, marigold, maidenhair tree, narcissus and aster. The results showed that 1-year-old Pinus sylvestris var. Mongolica had no significant effect on the germination rate of the maitake and petunia seeds, but had significant effects on the germination rate of the other 4 species of flower seeds. Germination had significant effects on the germination rate of other three kinds of flower seeds, but no significant effect on the germination rate of other flower seeds. The 5-year-old branch extract had significant effects on the germination of three species of flower seeds, All the tested materials had significant effects. The extracts of the living leaf had no significant effect on the germination of marigolds and ghost butterflies, and had significant effects on the germination of the other four kinds of flower seeds.
