Study on the water culture rooting characters on different parts of "Xianglin" new Populus nigra clones;

To plantlet regeneration,different growth regulator levels played important roles in rooting culture.

Taking Phalaenopsis s tube seedlings as the test materials,this paper researches on the successive transfer culture medium and rooting culture medium,introduces the test materials and test methods,analyzes on the test results,and through the comparison of the two tests,draws the conclusion that in Phalaenopsis s successive transfer culture the No.

The effects of various factors including different selecting period and treatment of material, browning control, concentration of Non-organic, phytohormone and light on adventitious bud induction, multiplication and differentiation, rooting culture of Xinli No.

2mg/L for rooting.

The buds were transferred into the rooting medium when it reached 2- 3 cm.

The seedlings of Leucadendron galpinii were used as the explants and the effects of different levels of the factors on axillary shoot proliferation and rooting were studied with orthogonal design.
