Why is it important?
1.The solution from the soils with rice bran has contradictory effects that not only decrease but also increase germination. 2.Exposure of seeds to light was an environmental factor and high germination activity and shallow dormancy of seed were physiological. The recovered soil solution promoted germination when these factors were not optimized. 3. A low content of DO was a stimulating factor for germination. 4.Germination increased with decrease in pH of soil solution, as long as the pH ranged from 4.0 to 7.0. This finding indicates that pH is also a factor that promotes germination.
Perspectives
The control of the growth of M. vaginalis in organic paddy fields is difficult because the efficacy of this material is unstable. That is because the soil solution has the ability to promote the germination.
