The effect of C19 supernatant on the germination rate of cucumber seeds was studied, the result showed that 100 × dilution improved the germination rate of cucumber seed significantly.

When concentrations of polyethylene glycol(PEG)raised to 15%,germination speed,germination exponent,vitality exponent,sprout length decreased in diffent extent.

This paper expounds the process and method of the germination test of the seeds of gleditia sinenssis, and draws a conclusion that the germination speed of the seeds treated with concentrated sulphuric acid for 40 min is higher, the germinating capacity of the seeds marinated in high-temperature water is higher, and the geminating capacity of the seeds accelerated in heat zone is high.

The result showed that as water potential decreased,germination percentage,speed of germination,germination index,vigor index,sprout length,roots length,R/S(ratio of root to shoot),fresh and dry weight of plant decreased in different extent.

Study on correlation between Atractylodes macrocephala viability and germination rate;

Effects of various seed sources and different storage conditions on seed germination rate of Valeriana officinalis;

Study on the seed germination rate improvement of centipedegrass;

This study is focused on the effects of different soaking media on rate of germination and length of shoots of germinated brown rice.

The experiments and comparison indicate that the method can raise the uniformity of drying; improve the rate of germination; shorten the drying time; increase the rate of production and save energy.

3gram seed; The seed s rate of the disrepair is lowest which got by the threshing method of hammering by manpower, and it s purity and rate of germination is topmost; The seed threshing method of the wood knife threshing machine(sieve poleF 0.
