Abstract

The present invention discloses the method of changing low temperature treatment condition to shorten wheat seed germinating time. The method includes the following steps: setting the seed inside germination dish on sand paper bed and adding proper amount of clear water; the subsequent setting the germination dish at 3 deg.c for 48 hr; and finally setting the seed at 20 deg.c inside germination case for 3 days to germinate. The present invention provides the method of shortening wheat seed germinating time to measure the germination rate of wheat seed and facilitate wheat storing.

Description

Change the low temperature treatment condition to shorten wheat seed germinating time method

Affiliated technical field

The present invention relates to seed germinating method, be specifically related to change the low temperature treatment condition to shorten wheat seed germinating time method.

Background technology

During the wheat seed warehouse-in,, generally before warehouse-in, need do the wheat seed germinating test in order to determine this batch seed germination rate.Wheat class dormant seed among the State Standard of the People's Republic of China GB/T3543.1-3543.7-1995 " crop seeds inspection procedure " adopts low temperature treatment, promptly handle 3d at temperature 5-10 ℃, under regulation normal temperature, germinate then, usually germinating time is wanted two weeks, and the obvious time is too of a specified duration on this germinating method program.

Summary of the invention

The objective of the invention is to: a kind of change low temperature treatment condition to shorten wheat seed germinating time method is provided, adopts this method to shorten the germination test time, know seed germination rate in advance, make things convenient for seed in time to put in storage.

Technical solution of the present invention is: this germinating method carries out according to following steps: at first, the little wheat seeds of new results place in the germination dish casting bed, proper amount of clear water; Secondly, little wheat seeds were placed 3 ℃ of conditions of temperature following 48 hours; At last, the seed of low temperature treatment after 48 hours placed in 20 ℃ the germinating box 3 days, the germination result of wheat seed.

Test is the wheat seed of early June results with planting, and red skin wheat is to raise wheat No. 5, and white skin wheat seed is Shan 3124, Shan farming 7859, universal love 7422.Seed was put dish simultaneously June 14.The seed that 100,4 repetitions of every repetition, casting bed, normality are handled earlier 6 ℃ handle in the germinating box that was placed on 20 ℃ in 3 days, the seed of low temperature treatment is placed in 3 ℃ the refrigerating chamber, takes out after 48 hours to be placed in the same germinating box.The result is as shown in table 1.

Wheat is in the germination result of normal temperature and low temperature treatment contrast

		June 19	June 22	Add up to
		June 19	June 22	Add up to	Raise wheat No. 8	Normal temperature	5	27	32％

Table 1

From the germination result of table 1 as can be known, through the wheat seed of 3 ℃ of low temperature treatment, comprise that the 5 day time of a low temperature treatment time need just can obtain the result of germinateing more accurately.

Embodiment

Germinating method of the present invention: at first, the little wheat seeds of new results place in the germination dish casting bed, proper amount of clear water; Secondly, little wheat seeds were placed 3 ℃ of conditions of temperature following 48 hours; At last, the seed after the low temperature treatment placed in 20 ℃ the germinating box 3 days, the germination result of wheat seed.

The wheat seed of results carries out germination test, kind with early June: red skin wheat is to raise wheat No. 5, and white skin wheat is Shan 3124, Shan farming 7859, universal love 7422, is both and puts dish June 14, is both at casting bed and handles.The result is as shown in table 2.

The wheat result of under low temperature treatment, germinateing

		June 19	June 22	Add up to
		June 19	June 22	Add up to	Raise wheat No. 8	Low temperature treatment	92	1	93％
Shan 3124	Low temperature treatment	95	1	96％	Raise wheat No. 8	Low temperature treatment	92	1	93％

Claims

1. change the low temperature treatment condition to shorten wheat seed germinating time method, it is characterized in that: this germinating method: at first, the little wheat seeds of new results place in the germination dish casting bed, proper amount of clear water; Secondly, little wheat seeds were placed 3 ℃ of conditions of temperature following 48 hours; At last, the seed after the low temperature treatment placed in 20 ℃ the germinating box 3 days, the germination result of wheat seed.
