Embodiment 1

[0022] A kind of method that removes sweet-scented osmanthus seed dormancy fast, comprises the following steps:

[0023] Seed collection: Harvest when the osmanthus fruit turns blue-purple from late April to late May, remove the pulp, clean the seeds and dry them;

[0024] Screening and disinfection: pick out a large, plump, pest-free seed, first soak it with 3% potassium permanganate solution for 30 minutes, then pour out the solution and stuff it for 10 minutes, carry out more sufficient sterilization in a closed space, and then wash the seeds clean and dry;

[0025] Mechanical treatment: rub the two ends and four sides of the osmanthus seeds with sandpaper, subject to the endosperm just exposed, be careful not to damage the embryo when rubbing the two ends;

[0026] Soak the seeds: Soak the mechanically treated seeds for 72 hours in a mixed solution containing 1200mg / L gibberellin and 20mg / L lanthanum nitrate;

[0027] Low-temperature stratification: Mix the soaked seeds ...

Abstract

The invention belongs to ornamental horticultural seedling raising technology, in particular to a method for quickly releasing dormancy of sweet-scented osmanthus seeds. The steps include: from late April to late May, when the sweet-scented osmanthus fruit turns blue-purple, harvest, remove the pulp, clean and dry the seeds; pick out a large, plump, pest-free seed, and use permanganate Soak in potassium solution for 30 minutes, pour off the solution and suffocate for 10 minutes, wash the seeds and dry them; rub the two ends and four sides of the osmanthus seeds with sandpaper; soak the mechanically treated seeds with a mixed solution of gibberellin and lanthanum nitrate; Mix the soaked seeds with wet sand, put them into a container, cover the surface with plastic wrap, punch holes, and carry out low-temperature stratification. The operation method of the invention is simple and easy, has low cost and high germination rate, and is suitable for both test and production needs.

Description

technical field [0001] The invention belongs to ornamental horticultural seedling raising technology, in particular to a method for quickly releasing dormancy of sweet-scented osmanthus seeds. Background technique [0002] Osmanthus fragrans seeds have certain dehydration sensitivity and deep dormancy. The mature seeds of that year need to be stratified and stored for about half a year before they can break the dormancy, which takes a long time and is not conducive to rapid seedling growth. And during the dormant period, no matter whether the seeds are sown in the ground or stored indoors, they may suffer unnecessary losses due to insect pests, rodent damage and mildew. The conventional method of breaking dormancy is to accelerate the germination of sweet-scented osmanthus seeds stored in mixed sand through wet sand treatment. This method takes a long time and has a low germination rate. Zhang Yi et al. (Zhang Yi, Effects of gibberellin seed soaking and low-temperature stra...
