A method for collecting and storing tulip pollen

Abstract

The invention relates to a method for collecting and storing tulip pollen. The method is characterized by comprising the following steps: selecting buds getting ready to burst at a big bud stage in the morning, pushing petals aside slightly with hands, collecting anther by using pliers, putting the anther into a plastic culture dish appropriate in size after the anther is collected, and marking the pollen collection date and the variety information on an upper cover of the culture dish; putting the collected pollen into a room together with the culture dish, putting the culture dish with the pollen into a sealed glass box, putting a drying agent on the bottom of the glass box, arranging a meshy clapboard above the drying agent, putting the culture dish with the pollen on the meshy clapboard, and finishing dehydration after 24 hours; finally, taking the dehydrated pollen out, covering the upper cover of the culture dish, and putting the culture dish in a drying box, then sealing the glass drying box, and storing the drying box for later use under the condition of no direct sunlight at room temperature. The method disclosed by the invention is safe and reliable and simple to operate, the space is saved, and the problem that the tulip pollen cannot be stored for a relatively long time under the natural condition, and the flowering asynchronism problem occurring in a tulip breeding process, and the like are solved.

Description

technical field [0001] The invention relates to a pollen collection and storage method, in particular to a tulip pollen collection and storage method for harvesting and short-term (30 days) storage tulip pollen germplasm, belonging to the field of plant developmental biology. Background technique [0002] Tulip (Tulipa) is an important perennial bulbous flower belonging to Liliaceae (Liliaceae). It can be used as fresh cut flowers, landscaping and potted plants, and has a wide range of uses. Almost all tulip varieties are not self-pollinated and must be artificially pollinated to obtain ideal yields and high-quality seeds. [0003] Because the natural flowering period of tulips is very short, about 10 days on average, so the biggest difficulty encountered in the tulip breeding process is not meeting the flowering period. In the practice of tulip breeding, the storage time of tulip pollen reaches 30 days, which can fully meet the needs of artificial cross pollination. Relat...
