花卉组培苗水培基质筛选研究

Study on the selection of the substrates during the water-culture of tissue culture flower

针对水培花卉组培苗存在的固定难、根系易收缩、植株易失水等问题,在水培羽裂绿蔓绿绒、绿巨人、蝴蝶兰中进行水草、农用岩棉、花泥、海棉等4种不同基质固定栽培试验。结果表明:在花卉组培苗水培生产中,采用适当的固定基质有利于水培成功,但是不同类型根系的花卉宜选用不同的固定基质。

The study selected the tissue culture seedlings of Philodendron selloumc. Koch, Spathiphyllum Supreme and Phalaenopsis amabilis culture to water culture, and used the aquatic plant, agricultural rockwool, sponge and rubber dough for substrates. Comparing with the seedlings cultured in just water solution. Results showed that it was better for the tissue culture seedlings to grow up with the suitable substrate in water culture. And the suitable substrate was not all the same for different culture flowers.
