Method for raising seedlings of rosa chinensis var.spontanea by cutting in winter

Abstract

The invention relates to the technical field of seedling breeding, in particular to a method for raising seedlings of rosa chinensis var.spontanea by cutting in winter. According to the specific technical scheme, the method for raising the seedlings of the rosa chinensis var.spontanea by cutting in winter comprises the steps of collecting autumn shoots of rosa chinensis var.spontanea in winter; trimming the autumn shoots and then successively carrying out treatment in a carbendazim solution and a rooting reagent; inserting cuttings into a substrate of a plug tray, putting the plug tray into awater containing tray and sealing the plug tray and the water containing tray; and finally carrying out seedling stage management and protection. According to the method, the problems that a plant enters a dormant state in winter and is slow in physiological metabolism, the content of an in-vivo growth inhibitor is increased, and formation and growth of regenerative tissue are seriously affected when the seedlings are raised by cutting at this stage are solved.

Description

technical field [0001] The invention relates to the technical field of nursery stock breeding, in particular to a method for raising seedlings by cuttings of single-petal Chinese roses in winter. Background technique [0002] Single rose (Rosa chinensis var. spontanea) is a very ornamental species of Rosaceae (Rosaceae) Rosa rose group, produced in Hubei, Sichuan, Guizhou, and more common in the mountainous forest margins around the Sichuan Basin. In 1902, Augustine Henry first found the wild species of single-petal rose in the canyons near Yichang in western Hubei Province. Due to the serious destruction of its habitat and over-excavation, the number of plants of single-petal rose is relatively rare, and it has been listed as a very small population of wild plants, which has high protection and potential application value. The previous studies on single rose flower were mainly in the following aspects: inclusion extraction, germplasm resource investigation, phylogenetic re...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a method for raising seedlings by single-petal rose cuttings in winter, so as to promote the improvement and improvement of cutting seedling raising technology, and solve the problem of plants entering a dormant state in winter, slow physiological metabolism, and growth inhibition in the body. The content of the substance increases, and the cutting seedlings are raised at this stage, which seriously affects the formation and growth of the regenerative tissue.
