Description
The present invention relates to a kind of short daylight period treatment method of before being transplanted to the land for growing field crops, implementing for short day plant and long-day plant in the long-day processing method of seedling replanting before the land for growing field crops.
Having the controlling plant method of breeding time now, mainly is to regulate sowing time or transplanting phase, controls fertilizer and water condition, or sprays methods such as chemical substance in suitable breeding time.Over nearly 30 years, numerous educate the breeding material that scholar's custom will have a short day photoperiodic reaction hereditary capacity and eliminate, exactly because do not find a kind of effective ways of controlling its vegetative growth phase, like this, the breeding scholar is selecting plant to short day photoperiod insensitiveness as one of breeding objective, so that make the material of selection can be in region plantation widely.
Photaesthesia is examined the appearance of sterile short day plant, to the traditional adjusting short day plant method of vegetative growth phase, has proposed challenge.With the photaesthesia nuclear sterile rice is example, its fertility conversion mainly is subjected to the influence of photoperiodic induction, carry out the transition to reproductive stage (entering ear differentiation) in vegetative growth phase and need the short-day condition, and break up meiosis stage during this from entering branch stalk, be the photoperiodic induction stage of fertility conversion, this stage needs the long-day condition.Existing method is to sow in advance because the accumulation of temperature and after the Summer Solstice day long by the long condition that shortens under, just enter ear differentiation, promptly just enter reproductive stage (also claim to nourish and grow and reproductive growth develops simultaneously the phase) through the after date of nourishing and growing for a long time.In this way, though satisfy the requirement of fertility conversion to long day condition, plant but can only make in 1 year once, not only reduced the rice field cropping index, increased seed costs, and because male sterile line prolongs vegetative growth phase, total leaf number and elongation internode number increase, plant height is higher, during the production of hybrid seeds, the plant height of male sterile line can increase the difficulty of pollination and pollination than male parent height.
Often need to utilize kind for long according to plant, and day long sensitive varieties need just can be finished young fringe growth course under long day condition, i.e. the reproductive growth process to long sensitivity of day.Thereby some days long sensitive varieties, even the method by custom is sowed in advance, can not satisfy it to long requirement of day, this just makes sowed in autumn and winter, use some day long sensitive varieties become impossible, especially when hybridization, use day long responsive male parent or female parent, more difficult realization flower synchronization.
Task of the present invention provides a kind of new method, makes plant variety with photoperiodic reaction or male sterile line or the male parent can be by the production of hybrid seeds or production requirement smoothly by the photoperiod, and can control breeding time and plant height.As paddy rice, can make the strong photaesthesia nuclear water of photosensitivity educate paddy rice and can also can also make rice culture in the strong late rice work of photosensitivity by the semilate rice production requirement production of hybrid seeds by the early rice time production of hybrid seeds of breeding time.To wheat, as two being wheat, when the production of hybrid seeds, can utilize to day long sensitivity the winter habit material as father and mother this, the father and mother with winter habit originally are eared in advance bloom, satisfy the requirement of this flower synchronization of father and mother.
The theory of institute of the present invention foundation is, can be divided into basic vegetative period and variable vegetative growth phase the vegetative growth phase of crop, the former depends on the hereditary capacity of crop itself, is immutable, and the latter is decided by that crop is in the sensitivity of growing period to photoperiod and temperature, it is the variation of photoperiod and temperature condition, can change the variable vegetative growth phase of crop, can prolong, also can shorten, thereby can regulate the breeding time of crop by the control photoperiod.
The present invention is achieved in that for short-day plant, before being transplanted to the land for growing field crops, covers seedling with lighttight material, and the control light application time is handled continuously, makes it in advance by the short day photoperiod.Use lighttight material,, give the natural lighting below 11 hours every day, handled continuously 8-12 days, keep ventilated in the covering as light screening materials such as black plastic or black cloths; For long-day plant, it to be sowed in advance, growing seedlings in the seedbed, to photophase, controls the light application time of every day at seedling development, handles continuously, makes it in advance by long photoperiod day.In the sense phase, the long photoperiod that gives every day more than 14 hours handles, and handles continuously 15-20 days, utilizes natural daylight daytime to long day plant, and replenish with artificial light source evening.The light intensity of artificial light source is in the 1500Lux.Concrete operation is such: to short day plant, as paddy rice, in nursery period or post seedling period, cover shading with light screening materials such as black plastics, 8 o'clock every mornings were opened covering, it were built during 6-7 in the afternoon, handled continuously 8-15 days, when 50% enters ear differentiation, promptly finish processing.Other plant also can carry out same processing.Implement to handle in this short day that short day plant is finished by nourishing and growing to the transition of reproductive growth, enter reproductive growth period ahead of time.According to the production of hybrid seeds requirement of different plants, can regulate the time of this flower synchronization of father and mother, as required, decision sowing time and the time of handling in short day.Short day plant, as the photaesthesia nuclear sterile rice, the time from ear differentiation to the heading-stage is comparatively stable, under the natural daylight elongate member, can finish inducing of changing from the male-fertile to male sterile.For long day plant, according to the requirement of regulating flower synchronization and the production of hybrid seeds or production, material is sowed in advance, when it is grown to photophase, the long-day that gives every day more than 14 hours handles, be to utilize natural daylight daytime, replenish with artificial light source evening, and artificial light source can be an incandescent lamp, it also can be iodine-tungsten lamp, or the two mixing use, also can be other light source, light intensity is in the 1500Lux, pending material is transplanted to seed farm after entering female stamen differentiation, can be by production of hybrid seeds requirement in advance by the photoperiod, production of hybrid seeds program routinely gets final product the production of hybrid seeds.
Advantage of the present invention is, plant to short day photoperiod sensitivity can take artificial method to make it enter reproductive stage in advance, be not subjected to the long influence of natural daylight, make things convenient for the production of hybrid seeds, the nearly 2 years observation of person according to the study, the number of blade can reduce plant height and can shorten, the elongation internode reduces, reduction in the life period can improve land utilization rate, also is easy to select male parent.Need material through processing in long day, adopt artificial light source, prolong light application time, can make it fulfil reproductive stage ahead of schedule,, can make male parent or female parent can be easy to flower synchronization in the production of hybrid seeds period of discomfort, can utilize the winter habit material to make male parent preferably, improve hybrid generation's output greatly, when producing, can utilize a collection of being difficult under field conditions (factors) by photoperiodic long day responsive type kind or strain.
