Abstract

The invention discloses a rapid propagation method adopting tissue culture for Croton tiglium. The rapid propagation method comprises steps of disinfection of Croton tiglium seeds, acquisition of aseptic seedlings; proliferation of cluster buds, rooting culture, strong seedling culture, acclimatization and transplanting. According to the method, a Croton tiglium regeneration system is established and can be applied to storage and reproduction of germplasm resources of the Croton tiglium as well as research on genetic improvement, and defects of a traditional mode for improving Croton tiglium germplasm can be overcome.

Description

technical field [0001] The invention relates to a rapid propagation method for tissue culture of croton, belonging to the technical field of plant cultivation. Background technique [0002] Croton, Euphorbiaceae, also known as Shuangyanlong, Jiangzi, Mengzishu, etc. Croton tiglium L. , shrub or small tree, 3-6 meters high, shoots are sparsely stellate pilose, branches glabrous, leaves papery, ovate, sparsely elliptic, raceme, terminal, capsule elliptic, sparsely Short stellate hairs or nearly glabrous, oval seeds, about 1 cm long, 6-7 mm in diameter, flowering period from April to June, born in villages or mountain forests, prefers warm and humid climate, not cold-resistant, afraid of frost It is suitable for cultivation in areas with a temperature of 17-19°C, an annual rainfall of 1000mm, a year-round sunshine of 1000h, and a frost-free period of more than 300d. When the temperature is lower than 3°C, all the leaves of the seedlings will die. , Sandy loam soil with good d...
