Abstract
The invention discloses a method for breaking sweet-scented osmanthus seed dormancy. The method comprises the following steps of seed selection, seed soaking treatment, plasma treatment, comprehensive treatment by gibberellin and hydrogen peroxide, low-temperature stratifcation treatment and the like. According to the method disclosed by the invention, proper frequency, voltage and treatment time of the plasma treatment are selected so that the later low-temperature treatment time is shortened. As the gibberellin and the hydrogen peroxide are applied to the comprehensive treatment of the seed, a substance inhibiting seed germination is effectively broken, and the time for breaking the dormancy is shortened.
Description
Technical field
What the present invention relates to is a kind of method of breaking fast the fragrans seed dormancy.
Background technology
Sweet osmanthus is one of China's ten great tradition famous flowers, also is one of most precious flowers and trees of modern city greening.Its tree performance is graceful, flourishing, greenery are verdant, evergreen all the year round, especially tempting with the deep and remote fragrance of a flower that disappears, really be " monopolize three autumn jobs as harvesting, tilling and planting press many virtue ", be decided to be city flower by world-renowned tourist cities such as Suzhou, Hangzhou, Guilin.The demand of sweet osmanthus is increasing now, and the Fast-propagation of sweet osmanthus is a problem that can not be ignored.
Seed dormancy is the same with many woody plants with low temperature depositing, and fragrans seed also has one period long resting stage.The fragrans seed of now gathering is not sprouted then basically, only has through just germinateing spring in Second Year behind the winter dormancy.No matter seed sows in the ground still indoor seasoning in very long like this some months resting stage, all may and go mouldy because of insect pest, the plague of rats, suffers unnecessary loss.And the sweet osmanthus sowing time can be again about the October in autumn, yet the fragrans seed of gathering does not then also have breaking dormancy, can not sprout and grow seedlings.The method of conventional breaking dormancy is that the fragrans seed through the mulling storage is carried out vernalization through wet husky the processing, this method length that expends time in, and germination rate is low; Also have research and utilization gibberellin to soak again and come breaking dormancy through cold stratification, but still exist germination rate low, the problem that the time is relatively long is so it is very necessary further to study a kind of method of breaking fast the fragrans seed dormancy.
Summary of the invention
The present invention is directed to existing deficiency a kind of method of breaking the fragrans seed dormancy is provided.
The present invention realizes above-mentioned purpose by the following method.
A kind of method of breaking the fragrans seed dormancy, the method comprises the following steps:
(1) seed selection: during 4 ~ May, when the pericarp of fragrans seed changes hyacinthine into gradually by green, can gather.The rear watering stack retting of gathering is removed pulp, the seed that dries in the shade, mulling storage.Choose the full seed of results, dry at the moon place that ventilates;
(2) seed of choosing is cleaned with clear water first, the liquor potassic permanganate of then putting into 0.5 ~ 1% concentration soaked 1 ~ 2 hour, dried after cleaning with clear water;
(3) cold plasma that utilizes atmospheric dielectric barrier discharge to generate is processed the fragrans seed that obtains through step (2), the time of plasma treatment seed is 60 ~ 80 seconds, the power supply of described dielectric barrier discharge is high-frequency and high-voltage power supply, frequency range is 4kHz ~ 6kHz, and voltage range is 5kV ~ 7kV;
(4) with the fragrans seed in the step (3), be that 0.04 ~ 0.6% gibberellin was processed 1 ~ 2 day with mass fraction, be that 10 ~ 15% hydrogen peroxide was processed 1 ~ 2 day with mass fraction again, then put into cleaned container with the wet husky ratio according to 1:4 of preprepared through mixing, cover with preservative film, and prick the breathing that several apertures are beneficial to seed at preservative film, the refrigerator of putting into 2 ~ 4 ℃ carried out cold stratification 40 ~ 60 days.
Beneficial effect:
(1) technology of plasma treatment of the present invention comprises the time of having adopted suitable frequency, voltage and processing, so that later stage low temperature treatment time shorten.
(2) utilize gibberellin and hydrogen peroxide that seed is carried out integrated treatment, abolished effectively the material that suppresses seed germination, shortened the time of breaking dormancy.
