Abstract
The invention discloses a treatment method of seedless watermelon seeds, and belongs to the technical field of plant breeding. A main technical measure is as follows: hybrid fruits are harvested in 5 to 7 days after the hybrid fruits are physiologically mature, then a watermelon is immediately broken to obtain seeds, and melon pulp and the seeds are collectively sealed in a plastic barrel and fermented for 8 to 12 hours; the seeds are stored after being primarily treated and re-treated under the condition that the humidity is less than 15 percent and the temperature is less than 18 DEG C for standby application. By adopting the treatment method, the key technical problem that a germination rate of the seedless watermelon seeds is low can be solved, the treatment method is suitable for mass preparation of seedless watermelon seeds, and the seed preparation cost is indirectly reduced.
Description
Technical field
The present invention relates to the processing method of seed in a kind of production of hybrid seeds process, be specifically related to a kind of processing method of aspermous watermelon seed, belong to field of plant variety breeding technology.
Background technology
Aspermous watermelon owing to having, disease-resistant high yield high without seed, sugar content and storage tolerance, deeply by the producer, operator and consumers welcomed.Therefore, aspermous watermelon industry development in recent years is rapid.But there is " three is low " problem that seed collecting amount is low, germination rate is low and planting percent is low in process of production in aspermous watermelon.Wherein, the main cause that germination rate is low is because aspermous watermelon is hybridized by tetraploid and diploid parents to obtain, embryo development is incomplete, the absolute weight of embryo is lower, embryo is heavy only account for seed heavy 38.5%, embryo volume accounts for kind of a 60%-70% for shell inner chamber, also has the Embryos of significant proportion simultaneously, thus causes percentage of seedgermination low.
Affect the many factors of seed vitality as seed inherent cause, cultivation condition, the weather conditions of period of reaching maturity, kernel maturing, seed mechanical damage, seed drying and holding conditions etc., wherein the maturity of seed and drying mode and seed vitality closely related, be directly connected to the economic benefit of seed quality and seed produces and the growth of seedling.Do not have fully ripe its quality of seed greatly to reduce, seed collection is crossed late excessive rainfall in addition and kind of melon can be caused again to rot or plant interior germination, and extends the occupation of land time, increases labor management expense.In addition, seed postharvest handling improper measures also can cause the decline of percentage of seedgermination.Therefore, aspermous watermelon picking time, seed collecting and seed postharvest handling technology are most important in seed produces.
Summary of the invention
The technical problem solved: the defect existed for prior art, the invention provides a kind of processing method of aspermous watermelon seed, be intended to improve aspermous watermelon production of hybrid seeds percentage of seedgermination, reduce breeding cost, be applicable to the production of hybrid seeds of large area aspermous watermelon, for high-quality aspermous watermelon varities practice provides technical support in production.
Technical scheme: the processing method of a kind of aspermous watermelon seed provided by the invention, mainly comprises the following steps:
(1) to gather seed: the watermelon hybrid fruit of 5-7d after physiological ripening of gathering, reach 16 years of age gets kind;
(2) ferment: the seed of taking-up is put into container sealing and fermenting 8-12h together with melon pulp;
(3) seed just processes: after fermentation, seed is separated with melon pulp, with clear water rinsing 3 times repeatedly, remove foreign material, then by seed and ash mixing, even in container for stirring, under sealing, normal temperature and dark condition, place 18-24h, then use clear water rinsing 3 times, removing mucus and ash impurity, obtain totally moistening seed;
(4) seed reprocessing: the seed after step (3) just being processed is placed on the dry place of shady and cool ventilation and dries in the shade, and period forbids that the sun is directly exposed to the sun, and seed moisture proportion is remained within the scope of 8-10%.
(5) bask seeds: the fine day seed that step (4) to be dried in the shade the morning is placed on airing 2-4d on bamboo mat, seed is carried out selection by winnowing and sieves, remove not plump seed and impurity, then load in paper bag, leave humidity ﹤ 15% in, for subsequent use under the condition that temperature ﹤ is 18 DEG C.
Preferably, the described watermelon hybrid fruit of step (1) is the watermelon hybrid fruit of 7d after physiological ripening; Step (2) and step (3) described container are the food-grade sealed plastic barrel being greater than 100L.
Preferably, the time of step (2) described sealing and fermenting is 12h; Step (3) the described time of placing under sealing, normal temperature and dark condition is 24h.
Preferably, weight ratio when step (3) described seed and ash mixing is seed: ash=1:1.
Beneficial effect: the processing method of a kind of aspermous watermelon seed provided by the invention, compared with prior art tool has the following advantages:
(1) the present invention gather field growing physiological ripening after the hybridization fruit of 5-7d, aspermous watermelon seed quality significantly improves, and contrast with gathering at physiological maturity, its percentage of seedgermination improves 20%.
(2) melon pulp to be fermented together with seed and seed just processes, significantly improve percentage of seedgermination.
(3) seed dries in the shade and work of basking seeds subsequently, and the dehydration process that dries in the shade is slow, avoids the distortion of seed and the quick dehydration of local and the raising etc. of sprout inhibition levels of substance, keeps and facilitate the level of percentage of seedgermination further.
Embodiment
Mode below by embodiment further illustrates the present invention, but therefore protection scope of the present invention is not confined to following embodiment, but is limited by specification of the present invention and claims.
Embodiment 1
The processing method of aspermous watermelon ' jet peak ' hybrid seed production of hybrid seeds process seed
(1) to gather seed: gather and be grown on field, the watermelon hybrid fruit of 5-7d after physiological ripening, reach 16 years of age gets kind;
(2) ferment: the seed of taking-up is put into the food-grade sealed plastic cask fermentation 8-12h being greater than 100L together with melon pulp;
(3) seed just processes: after fermentation, seed is separated with melon pulp, with clear water rinsing 3 times repeatedly, remove foreign material, then by seed and ash mixing, weight ratio when seed and ash mixing is seed: ash=1:1, stirs at the food-grade sealed plastic barrel being greater than 100L, 18-24h is placed under sealing, normal temperature and dark condition, after use clear water rinsing 3 times, removing mucus and ash impurity, obtains totally moistening seed;
