Abstract
The invention discloses a method for breaking morning glory seed dormancy. According to the method, firstly, morning glory seeds are placed in a refrigerator with the temperature being -5 to 5 DEG C for 24 to 60 hours before seeding; then, the morning glory seeds are immediately put into hot water with the temperature being 50 to 70 DEG C to be soaked for 2 to 6 minutes, and the morning glory seed dormancy can be broken. The method has the advantages that simplicity is realized, the operation is easy, time and labor are saved, the morning glory seed dormancy can be broken, and the germination rates of the morning glory seeds can be improved.
Description
Technical field
The invention belongs to plant planting field, be specifically related to one and break the seed dormant method of morning glory.
Background technology
Lead a cow (Pharbitis nil (L.) Choisy), belongs to Convolvulaceae ipomoea, annual voluble herb.The flower of this Plants exactly likes horn-like, and therefore some place makes it do trumpet flower.Plantation morning glory is generally sowing the seed in spring, and Xia Qiu is bloomed, and its kind is a lot, the color of flower has indigo plant, bright red, pink, purple etc., and also having colour mixture, is common ornamental plants.Fruit ovoid, can be used as medicine.Morning glory leaf three splits, and base portion is heart-shaped.Flower is in white, aubergine or hyacinthine, and funnel-form, complete stool has coarse wool.Florescence contains with summer most.Seed has medical value.
General seed germination method has: (1) cold water or water seed soaking.The seed comparatively easily germinateed prior to seeding with cold water or warm water (35 ~ 40 DEG C) seed soaking, namely can take out sowing after seed coat deliquescing.(2) seed coat is dampened.The seed seed coat of lotus, India canna is hard, not easily absorbs water, and available cutter of frustrating galls or carves and hinders seed coat, then uses warm water (35 ~ 40 DEG C) seed soaking, after seed coat deliquescing, namely takes out sowing.(3) acid, alkaline treatment.Adopt acid, alkaline treatment seed, corrosion seed coat, cleans medicament with clear water after process.(4) chemicals treatment.(5) ultrasonic process.(6) freezing or cryosphere area method.To requiring the flower seed completing resting stage under low temperature and wet condition, there is obvious stratification effect.
Morning glory seed is because the reason of dormancy; germination rate and low; there is report blade to cut Pharbitis nil epidermis, utilize husky skin friction morning glory seed; imperial japanese morning glory seed is soaked seed by the Gibberellins solution of 10 ~ 250 mg/litre prior to seeding; the effect of low temperature can be replaced; promote that the methods such as it germinates carry out the method for breaking dormancy, but all waste time and energy, cumbersome.
Summary of the invention
One is the object of the present invention is to provide to be easy to operation, to break the seed dormant method of morning glory easily.
The present invention is achieved by the following technical programs:
One breaks the seed dormant method of morning glory, comprises the steps:
1) low temperature treatment
It places 24 ~ 60 hours by morning glory seed prior to seeding in-5 ~ 5 DEG C of refrigerators;
2) hot water treatment
By through step 1) the morning glory seed that processes puts into 50 ~ 70 DEG C of hot water immediately and soaks 2 ~ 6 minutes;
3) sow
By through step 2) the morning glory seed that processes takes out and can sow, and adopts cave dish seeding and seedling raising or field direct sowing and seedling.
Preferably, described refrigerator temperature is 5 DEG C.
Preferably, the described standing time in refrigerator is 48 hours.
Preferably, the temperature of described hot water is 60 DEG C.
Preferably, the described time of soaking in the hot water is 4 minutes.
In order to find optimum condition of the present invention, inventors performed following experiment.
Adopt multifactor one by one according to the optimum condition breaking morning glory seed germination.
One, different disposal is on the impact of seed germination time
Arrange as table 1 processes factor by low temperature treatment and heat treated different temperatures, different time, concrete outcome is in table 1.As can be drawn from Table 1, different disposal is not very large on the impact of seed germination time, and sprout time is 3 ~ 4 days, but with do not have treated seed to compare, its time reduces all greatly.
Table 1 different disposal is on the impact of seed germination time
Two, different disposal is on the impact of seed germination rate
Arrange as table 1 processes factor by low temperature treatment and heat treated different temperatures, different time, concrete outcome is in table 2.As can be drawn from Table 2, different disposal is comparatively large on the impact of seed germination rate, and learn through comparing, refrigerator process 5 DEG C, 48h, the germination rate of hot water treatment 60 DEG C, 6min reaches 90%, and treatment effect is best.
Table 2 different disposal is on the impact of seed germination rate
To sum up, optimum treatment mode of the present invention is: place in 5 DEG C of refrigerators after 24 hours and take out seed, puts into 60 DEG C of hot water immediately and soaks 4 minutes.
The present invention is simple, time and labour saving, can effectively break morning glory seed dormancy, improves morning glory percentage of seedgermination.
