A method for rapid and efficient germination of rare and endangered plant Akane baoshansi

Abstract

The invention provides a method for the rapid and efficient germination and seedling growth of the rare and endangered plant Akane baoshan, comprising the following steps: (1) collection of fruit and seeds: collecting Akane baoshan fruit with gray-green exocarp; peeling off the exocarp; taking out the seeds Baoshanqian seeds with light brown or dark brown leopard-like membranous skin and slightly bony endosperm or bony endosperm; (2) seed disinfection; (3) water moss germination: spread a layer of water moss, and spread fresh seeds on the water moss (4) Preparation of transplanting substrate; (5) Transplanting: root directly in the sphagnum, the radicle grows to 3±0.3cm, the radicle has root hairs, and the radicle axis is green When transplanting to the seedling-raising container, the roots with root hairs are planted in the seedling-raising matrix, the thick endosperm of the radicle rachis and the cotyledons are exposed outside the seedling-raising matrix, and 800 times of carbendazim or chlorothalonil is poured; (6) management. The invention greatly improves the germination rate and seedling rate of Baoshan Qian seeds, shortens the seedling raising time, makes the seedlings germinate neatly, and is easy to manage.

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 ...
