Embodiment 1

[0020] This embodiment provides the experimental procedure of Wang Lian's forced self-breeding.

[0021] The Wanglian used in this embodiment comes from Xi'an Botanical Garden, Shaanxi Province, and the variety is Cruz Wanglian.

[0022] In 2014, this experiment selected three Wanglian plants that were planted separately in different waters and far away as the test objects. Beginning at the end of July 2014, the buds produced on the plants were selected as the fourth and subsequent robust flower buds for testing. This experiment was carried out from the end of July to October 20, 2014.

[0023] Three treatments were set up in this experiment. Treatment 1: Control group (without any treatment). Treatment 2: Bagged isolation but no hand pollination. Treatment 3: bagging and applying the method provided by the present invention for artificially assisted pollination. Specifically, treatment 2 is to carry out bag isolation from 16:00 to 19:00 on the day when the group of lotus...

Abstract

The invention discloses a single plant prinsepia utilis selfing method, and belongs to the technical field of plant propagation. The selfing method for the single plant of the prinsepia utilis comprises the following steps: bagging and isolating at 16: 00-19: 00 on the day when a prinsepia utilis flower bud blooms for the first time; quickly knocking the stamens at 16: 00-19: 00 on the next day to enable pollen of the stamens to be dispersed; bagging and isolating again until the prinsepia utilis flower buds sink into water. According to the method disclosed by the invention, the selfing of the single plant of the prinsepia utilis is realized by utilizing the characteristic that the plant can motivate potential under an adverse condition. According to the method, the problems that no pollination person exists and the pollination rate is zero or extremely low under the bagging condition when the prinsepia utilis is used as an entomophilous flower are solved, and the seed can be obtained by selfing only by planting one prinsepia utilis.

Description

technical field [0001] The invention belongs to the technical field of plant propagation, and relates to a method for the self-crossing of a single lotus root. Background technique [0002] Giant waterlily is a general term for plants of the genus Victoria in the Nymphaeaceae family. There are two native species in this genus, V.amazonica and V.cruziana. Native to tropical South America, perennial aquatic herb. Wanglian is a rare giant aquatic flower with a peculiar shape. It has a very high ornamental value and is also of great value in the study of species evolution. [0003] The problem of breeding and reproduction of lotus root has not been well solved. The main reasons are as follows: lotus root is native to tropical regions and is a perennial plant, but it cannot naturally overwinter in winter in other regions other than its origin. , can only be cultivated annually and propagated by seeds every year, so obtaining mature seeds has become the key; due to the huge plan...
