Horticulturist usually seeding seed beans and white flower and some times Okra faba beans directly in the soil or they soak it with osmotic solutions, particularly PEG or Manitol
most beans and legumes produce a hard seeds owing to seclerids columnar types enable the seeds to dry to high extent drying degree, where, seed starch highly hardened. other seeds possess valve for irreversible disposed water from seed. When these seeds are soaked adsorb water quickly and swollen rapidly cracking the seed components including the embryos and damage them. Resemble phenomenon occurred In regard white flower tannin free faba beans, since they devoid of tannins which regulate the speed of water absorption
Hydro-priming is carried out to apply the Tetrazolium test to common beans (Phaseolus vulgaris). Thus, water is not the problem. How many grams is the 100 seeds of these species. I believe that we have to think about mechanical damages to the seed embryo-axis during the seeding period, seed fermentation during the pre-planting period, or both. Walter
