Abstract

The germination method of a kind of tobacco seed, it relates to Nicotiana tabacum L. Germination Technique field.Its packet technology scheme is: first takes appropriate tobacco seed and is put in the container containing 0.2%KC1 and 150mg/L gibberellins (GA) treatment fluid；Soak seed 8 hours under 28 degree celsius temperature, then seed is taken out；Put in the seed germination box of 28 degrees Celsius after wrapping up with wet towel or gauze, through 57 days.The present invention it can significantly improve the fresh and alive quality of the germination percentage of tobacco seed, germinating energy and sprout.

Description

A kind of germination method of tobacco seed

Technical field

The present invention relates to Nicotiana tabacum L. Germination Technique field, particularly relate to the germination method of a kind of tobacco seed.

Background technology

The most domestic research for the Germination Technique of tobacco seed is the most on the low side, the most general that just use or Nicotiana tabacum L. The Stratification technique of seed, Main is: at the container of cleaning, loading 50 ~ 55 DEG C of warm water, the water yield is 5 times of seed volume, will Seed immerses in warm water and is stirred continuously, and stops stirring, then soaks 8 ~ 12 hours, make seed suction when water temperature drop to 30 DEG C Moisture, then water outlet, drain away the water, and binds up with gauze, and outside wraps the piece of sack or towel soaked again, urges in putting basin alms bowl Bud, this method is referred to as hoting water treatment of seeds, and this is the most the most frequently used germination accelerating method, and this method is simple and convenient, but there is also all Many problems: seed sprouting is slow, and bud gesture is weak, it is irregular to emerge, big seedling phenomenon is serious, and such as seed dormancy, speed of emergence is more And bud rate is low slowly,.Nicotiana tabacum L. is a kind of very popular crops, occupies critical role, but Tobacco Seed Germination is slow on producing And irregular, in storage process, easy naturally-aged causes vigor to reduce, and the most how to accelerate seed germination and promotes that seed goes out Seedling seems particularly significant.

Summary of the invention

It is an object of the invention to provide the germination method of a kind of tobacco seed, it can significantly improve the germination of tobacco seed The fresh and alive quality of rate, germinating energy and sprout.

In order to solve the problem in the presence of background technology, the present invention is by the following technical solutions:

First take appropriate tobacco seed to be put in the container containing 0.2%KC1 and 150mg/L gibberellins (GA) treatment fluid；

Soak seed 8 hours under 28 degree celsius temperature, then seed is taken out；

Put in the seed germination box of 28 degrees Celsius after wrapping up with wet towel or gauze, through 5-7 days.

Compared with the conventional method, the inventive method beneficial effect following points:

1, with batch tobacco seed, the seed processed by this method, can improve the bud rate of bud rate 5%-8%.

2, with batch tobacco seed, the seed processed by this method, germinating energy can be emerged 93% for 5 days, be improved 4 percentages Point.

3, with batch tobacco seed, the seed processed by this method, sprout quality significantly improves, fresh and alive strong shape, vigor By force.

4, with batch tobacco seed, the seed processed by this method, Phase ofsprouting improves, and Seedling size is uniform.

Detailed description of the invention

A kind of germination method of tobacco seed, its detailed description of the invention and principle are as follows:

It is to be understood that the processing method of seed germination, first understand seed germination: sub-sprouting refers to what seed started from imbitition A series of orderly physiological process and morphogenetic process, sprouting of seed needs suitable temperature, certain moisture, sufficient Air, during seed germination, is first water suction, makes seed coat expand, softens, more oxygen visible through the seed coat can be made to enter after seed immersion Entering Interior Seed, carbon dioxide visible through the seed coat is discharged simultaneously, and the physical state of the inside changes；Next to that air, seed exists The vital movement of the series of complex conducted in germination process, only seed are constantly breathed, and obtain energy, Cai Nengbao Being normally carried out of card vital movement；Being finally temperature, temperature is too low, and photosynthesis weakens significantly, and Repiration is suppressed, light Symphysis productivity reduces, the decomposition of Interior Seed nutrient substance and other a series of physiological activities, is required at a suitable temperature Carry out.

The present invention uses the principle that 0.2%KC1+150mg/L gibberellins (GA) processes: gibberellins (GA) is as a kind of plant Regulator, can break seed dormancy, accelerates Starch Hydrolysis in endosperm, promotes germination, and potassium is the monovalence that plant part is required Cation, it is dissolved in water with ionic condition, and its major function is relevant with plant metabolism, and the present invention is in Nicotiana tabacum L. The impact of mda content in germination characteristic and sprout body, improves the sprouting condition of tobacco seed, can be fast and effectively Improve the germination percentage of tobacco seed, germinating energy and the fresh and alive quality of sprout.

Concrete operation method: take appropriate tobacco seed and be put in the appearance containing 0.2%KC1 and 150mg/L gibberellins (GA) treatment fluid In device, soak seed 8 hours under 28 degree celsius temperature, then seed is taken out, after wrapping up with wet towel or gauze, put into 28 Degree Celsius seed germination box in, through 5-7 days, seed will fully be sprouted.
