BOTANY

Detailed explanation-1: -The Petri dish germination test is used for crops with small seeds or those requiring light. Seeds are placed on a vacuum template to get the correct number of seeds for insertion into the Petri dish. The Petri dish contains a moistened paper substrate (blue blotter).

Detailed explanation-2: -But if it’s too cold or too wet, too warm or too dry for that particular seed, it will fail to germinate at all. By soaking (presoaking) seeds in water ahead of time, you remove some of those barriers so the seeds are ready to sprout by the time you stick them in the soil.
