无籽西瓜种子采收后不要立即播种,需贮藏一个时期。据试验,无籽西瓜种子,在室温条件下贮藏2年,发芽率仍达60%;冰箱贮藏(8℃,下同)和干燥器内贮藏7年,发芽率仍达耶叽。因此‘无籽西瓜种子须贮藏在于操、低温的环境中,空气相对湿度在60%以下,温度在匕℃以下和种子的 Seedless watermelon seeds do not immediately sowed after harvest, to be stored for a period. According to the test, seedless watermelon seeds, stored at room temperature for 2 years, the germination rate is still up to 60%; refrigerator storage (8 ℃, the same below) and dryer for 7 years, the germination rate is still Dayeji grumble. Therefore, seedless watermelon seeds must be stored in the operating environment, low temperature, the air relative humidity below 60%, the temperature below the dagger and seed
