Common problems and cause analysis in watermelon seed germination

(Agricultural Wealth Network) 1. Seed coat cracking. The causes are: first, soaking the seeds too long; second, the soaking temperature being too high; third, the germination temperature being too high; fourth, old seeds. 2. Yellow tips on the sprouts. Causes: first, soaking the seeds for too short a time or poor moisture retention during germination, resulting in a lack of water; second, the germination temperature being somewhat high; third, old seeds. 3. Uneven germination. Causes: first, the seed coat being too large or the seeds floating, so soaking is uneven; second, varietal reasons, such as Early Flower; third, old seeds. 4. The seed coat becoming sticky and sour. Causes: first, no acid treatment being done at seed collection, so there is a lot of material attached to the seed surface; second, the germination wrap being too wet, too tight or too large, with poor air permeability; third, the germination temperature being somewhat high.
