Solid substrate priming method of seeds of seedless watermelon

Abstract

The invention discloses a solid substrate priming method of seeds of a seedless watermelon, relating to a seed treatment technology and comprising the following six steps of: firstly, selecting and pretreating a solid substrate, secondly, selecting and treating seeds, thirdly, priming the seeds, fourthly, separating the seeds from sawdust, fifthly, drying, and sixthly, storing the seeds at a low temperature. The method for conductivity measurement or activity measurement of dehydrogenase is adopted when the seeds are selected according to needs, the seeds with poor innate vigor are removed to avoid unnecessary priming waste. In the method, sawdust is used as the solid substrate, therefore, the material is easily available, the cost is low, the specific gravity and the friction coefficient are low, the operation is relatively convenient, the surface of a screen is less worn when in screening or separating, the seeds are cultured in darkness in an incubator so that electric power is saved, the priming effect of seeds is extremely ideal, and the positive effect on seed germination is superior to the priming effect of other solid substrates.

Description

technical field [0001] The invention relates to a seed treatment technology, in particular to a triggering method for improving the germination rate and vigor of triploid watermelon seeds by using sawdust as a solid substrate. Background technique [0002] CN101422098 discloses "a kind of method for improving the germination rate and seedling rate of triploid watermelon seeds" of Northwest Agriculture and Forestry University. The watermelon seeds are wrapped with wet towels or mixed with watermelon seeds with perlite and water, and placed in a light incubator. cause. CN101828443 has announced " a kind of solid matrix priming method that improves watermelon seed germination rate and vigor " of Beijing Academy of Agriculture and Forestry Sciences, is (3-5): (2-3) mixes by mass ratio with vermiculite and water, seed and solid matrix The mass ratio of the mixture is (30-40):(240-250), the vermiculite, water and seeds are mixed well, put into a container, and cultured in a seale...

AI Technical Summary

Problems solved by technology

In short, vermiculite or perlite or sand are useful solid substrates in the prior art. These solid substrates have a large specificity and a large friction coefficient. When using a sieve for material selection and separation, the screen is severely worn and the operation is laborious. When separating seeds and solid substrates, the particle size of vermiculite and perlite is close to the size of watermelon seeds, and the sand is easy to accumulate on the screen surface in water, and the separation is not convenient, and the price of vermiculite and perlite is relatively high

After searching, no data reports have been found on using sawdust as a solid substrate to prime seeds
