Means for simultaneous activation of germination of wheat seeds and increase the resistance of seedlings to water stress

 

(57) Abstract:

The invention relates to agriculture and chemistry of biologically active substances. As a means for the simultaneous activation of germination of wheat seeds and increase the resistance of seedlings to water stress proposed 4-chloromethyl-2(furyl-2)-1,3-dioxolane by pre-sowing treatment of seeds. The proposed tool on its performance surpasses the similar as in normal conditions and under water stress significantly improves seed quality of wheat seeds under drought, it can be used in the zone of risky agriculture. Claimed as a means substance has a higher solubility, stability and extends the number of biologically active substances that trigger the germination of seeds in normal conditions and under water stress. table 1.

The invention relates to the field of agriculture and chemistry of biologically active substances and can be used for simultaneous activation of germination of wheat seeds and increase the resistance of seedlings to water stress.

The disadvantage of existing technologies of cultivation of agricultural crops, especially in the areas of risky land is Dow in adverse conditions, including drought.

To study seed and increase plant tolerance to drought using the growth regulator Furlan is similar in structure and properties of the proposed drug. However, Furlan poorly soluble in water and metastabile /Patent RF N 2042326 from 27.08.95/.

As the proposed drug is supposed to be known chemical - 4-chloromethyl-2-(furyl-2)-1,3-dioxolane of the formula I:

< / BR>
As biologically active substances, including the claimed purpose, the substance was not applied. The method thereof is described /Gavrilova, S. P. , sarcina, So, Badovsky L. A. Synthesis and properties of furan 1,3-dioxolane// CHC. I an Improved method for the synthesis of furan 1,3-dioxolane - N 3. - 1983. - S. 325-328.

The task of efficient tools for the simultaneous activation of germination of wheat seeds and increase the resistance of seedlings to water stress.

This is achieved by the use of such 4-chloromethyl-2-(furyl-2)-1,3-dioxolane by pre-treatment of wheat seeds with a previously not described for him bioactive properties, simultaneously manifested in the activation of germination semasa, simultaneously activating the germination of wheat seeds and increased resistance of seedlings to water stress, characterized in that as a means used 4-chloromethyl-2-(furyl-2)-1,3-dioxolane by pre-treatment of wheat seeds.

The invention is illustrated by the following example.

Example. Step 4-chloromethyl-2-(furyl-2)-1,3-dioxolane on the germination of winter wheat varieties Partisan in normal conditions and under water stress.

The tool according to the invention and similar in structure and properties - Furyan used by pre-sowing seed soaking winter wheat varieties Partisan. For seed treatment used water disinfectant solutions according to the invention, with a mass fraction 0,01; 0,005; 0,001; 0,0005; 0,0001% and paralana - 0,001%. As a control were taken from seeds treated with water.

Seeds were germinated for 7 days. After 3 days from the start of germination half of the seeds from each sample was subjected to water stress. To do this, germinated seeds were laid out on a dry surface and dried in an hour.

Further germination of seeds, including those subjected to water stress, held in rolls of filter paper. Repeated experiments t is of the 7-day-old seedlings was determined height of sprouts, the length of roots and dry weight of bodies.

The measurement results were subjected to static processing.

The research results are summarized in the table.

The tool according to the invention in normal conditions (without drying) in the concentration range of 0.01 and 0.0001% is not inferior to the standard activity and optimal growth stimulating dose of 0.001% wt. increases height of sprouts 7-day-old seedlings on 46% of their mass by 40% in comparison with the control, while farolan increases the height of the seedlings by 22.3%, their mass - 38.5% compared to control.

Thus, the tool according to the invention in optimal growth stimulating dose of 0.001% wt. more effective than similar in structure and properties - farolan, and significantly improves sowing qualities of seeds of winter wheat varieties Guerrilla, which is caused by the perspective of its application.

Tests conducted with drying seedlings showed that the tool according to the invention in a concentration range of 0.005-0,0005% of its activity is at the level of the prototype and in the optimal growth stimulating dose of 0.001% increases the length of the seedlings by 57.9%, length of roots by 50% and weight by 13% in comparison with control, allowing you to save high Ruritania in optimal growth stimulating dose of 0.001% wt. its effectiveness is superior to similar in structure and properties - Furyan both in normal conditions and under water stress significantly improves seed quality of wheat seeds under drought, it can be used in the zone of risky agriculture.

Claimed as a means substance has a higher solubility, stability and extends the number of biologically active substances that trigger the germination of seeds in normal conditions and under water stress.
