Problems solved by technology

Hemerocallis has large flowers and slender pistils. If the traditional method of emasculation and bagging is used for hybridization, the stigma of the pistil after pollination will rub against the bagging, resulting in a greatly reduced seed setting rate.
[0003] Because the stigma of daylilies is soft, if the existing method is used to wrap the stigma, the covering covering the stigma will be easily blown off by the wind
In addition, when wrapping daylily stigmas, it is very easy to break the soft daylily stigmas, so it is not suitable for wrapping

Embodiment 1

[0024] A method for pollination of Hemerocallis plants, comprising the steps of:

[0025] 1) Cut tinfoil: 1.8cm×1.8cm;

[0026] 2) Use rectangular blunt-tip tweezers slightly thicker than the stigma of daylilies to make tinfoil paper like figure 1 The shown long column and square column are folded and pinched tightly to make a miniature tinfoil sleeve;

[0027] 3) Open the flower buds one day before the flowers of Hemerocallis bloom, and cover the miniature tinfoil bag on the stigma;

[0028] 4) After the flowers bloom, take off the miniature tinfoil sleeve, apply the pollen on the stigma, and put the same tinfoil bag back on the stigma, as in figure 2 shown.

[0029] 5) Do not remove the tinfoil cover on the stigma anymore. As the flowers wilt, the stigma loses its ability to pollinate and wilts gradually.

experiment example

[0031] The method of Example 1 and the traditional method of emasculation and bagging (stigma without casing) were used to carry out pollination contrast experiments on Hemerocallis fulva (scientific name: Hemerocallis fulva).

[0032] Test site: Xiaotangshan Experimental Base, Changping District, Beijing

[0033] Test time: 2013, 2014, 2015, 2016.

[0034] Experimental Group: The method of pollination of Hemerocallis plants comprises the following steps:

[0035] 1) open the flower buds one day before the opening of Hemerocallis flowers, and cover the stigma with the same miniature tinfoil as in Example 1;

[0036] 2) On the day when the flowers bloom, remove the miniature tinfoil sleeve, spread pollen on the stigma, and put the same tinfoil sleeve back on the stigma; complete pollination; until the flowers wilt and the stigma loses pollination ability. The pollination process includes: selecting flowers that bloom on the same day and collecting their pollen; the pollen col...

Abstract

The invention relates to a daylily pollination method. The method comprises the step of sleeving a hollow light tube on a daylily stigma to isolate the stigma, wherein one end of the tube is opened, the other end is closed, and the inner diameter thereof is slightly greater than the outer diameter of the daylily stigma. The pollination result cannot be influenced whether by wind or rain, the method is extremely suitable for the hybrid pollination of the daylily, the maturing rate of the pollination of the daylily under bad weather condition is greatly improved, and the pollination time is increased. Furthermore, the method is free from emasculation, and the breeding workload is lightened.

Description

technical field [0001] The invention belongs to the field of plant breeding, and in particular relates to a method for pollination of plants of the genus Hemerocallis. Background technique [0002] The flowers of plants of the genus Hemerocallis (Hemerocallis L.) are three-numbered flowers, each flower can only bloom for one day, and each flower has 1 pistil and 6 stamens. Pistils longer than stamens. as attached figure 2 shown. Hemerocallis has large flowers and slender pistils. If the traditional method of emasculation and bagging is used for hybridization, the stigma of the pistil after pollination will rub against the bagging, resulting in a greatly reduced seed setting rate. [0003] Because the stigma of daylilies is soft, if the existing method is used to wrap the stigma, the covering covering the stigma will be easily blown off by the wind. In addition, when wrapping daylily stigmas, it is very easy to break the soft daylily stigmas, so it is not suitable for wra...
