Quick and efficient germination seedling-formation method for rare endangered plant fosbergia shweliensis

Abstract

The invention provides a quick and efficient germination seedling-formation method for a rare endangered plant fosbergia shweliensis. The quick and efficient germination seedling-formation method comprises the following steps of 1, collection of fruits and seeds, wherein the fosbergia shweliensis fruits with epicarp are collected; the epicarp is stripped; the fosbergia shweliensis seeds with leopard membranes and endosperm ending sclerotin or sclerotin with light-brown or dark-brown seed coat are taken out; 2, seed disinfection; 3, germination accelerating by using sphagna, wherein a layer of sphagna is laid, the fresh seeds are laid on the sphagna, and another layer of sphagna is laid; 4, preparation of a transplantation substrate; 5, transplantation, wherein roots are cultured in the sphagna, when radicles grow to 3+/-0.3 centimeters, root hair grows out on the radicles, and radicle axes are green, seedlings are transplanted into a seedling raising container, the roots with the root hair are planted into a seedling raising substrate, the radicle axes and thick endosperm with which cotyledons are wrapped are exposed to the outer side of the seedling raising substrate, and a 800-fold carbendazim or chlorothalonil solution is applied; 6, management. By means of the method, the germination rate and the seedling-formation rate of the fosbergia shweliensis seeds are greatly improved, the seedling raising time is shortened, the seedlings regularly germinate, and management is facilitated.

Description

technical field [0001] The invention relates to the field of plant propagation, in particular to a method for rapid and efficient germination of the rare and endangered plant Akane baoshansi into seedlings. Background technique [0002] Shanxi (Fosbergia shweliensis) is a plant of the genus Rubiaceae, endemic to the Gaoligong Mountain area. It was rediscovered after 85 years of disappearance. Its wild population distribution is small, the population is small, and the number of existing plants is very small, which belongs to a very small population species. Very small population species are endangered due to their small populations and narrow distribution ranges. They are the most urgently in need of protection among threatened species. [0003] Through investigation and research, it is found that Baoshanqin takes many years to bear fruit, the fruit persists and hangs on the tree for 5-6 years, and it is difficult to distinguish between new fruit and mature fruit; the outer ...
