Description

The invention relates to the field of agriculture (seed science) and can be used for an objective assessment of the ability of seeds to provide in the field friendly, leveled shoots and good survival of plants during the early growing season. The seed germination energy is sometimes determined together with the assessment of their germination.

There are known methods for estimating germination energy and germination, providing for germination of seeds in various media:

- on corrugated paper in germinators;

- on wetted filter paper placed in Petri or Koch dishes;

- between the strips of moistened filter paper, rolled into a roll [1].

There are special devices for germinating seeds [2, 3,4].

Meanwhile, the above-mentioned methods and devices do not provide simplicity and reliability of germination, as breathing and moistening of seeds is difficult, and their damage to pests is also possible, which eliminates the objectivity of the germination energy.

There is also known a method of three-day germination of seeds at a temperature of 20 ° C in germinators filled 1/4 of their height with quartz sand [5]. But this method also has some significant drawbacks:

- sand weakly retains moisture and does not ensure the stability of seed moisture;

- the substrate is often the source of the spread of infections affecting seedlings;

- chemical interaction of seedlings through root excretions, which are growth inhibitors, is not excluded.

These factors cause significant differences in seed germination between individual repetitions of the experience, while the reliability of the estimated germination energy decreases.

We propose a new, simple to implement, cost-effective and objective way to evaluate seed germination energy.

This goal is achieved by three-day germination of seed material in germinators filled with quartz sand. Seeds are germinated in a thermostat at a temperature of 28-30 ° C, and the germinator is filled with sand at 1/4 of their height with a humidity of 70-80% in the thermostat. The sand is pre-impregnated with 200 mg of 10% warm, with a temperature of 40 ° C, an aqueous solution of gelatin food grade P 11 (TU9199-002-11717818), which ensures the stability of the substrate moistening.

To prepare the above solution, the large crystals of gelatin are pre-ground using a homogenizer.

At the end of germination, calculate the percentage of normally germinated seeds, reflecting the energy of their germination.

Minimal deviations from the average values between parallel samples, revealed when evaluating the effectiveness of the new method, as compared to the control, testifies to its greater reliability.
