What are the characteristics of seedless watermelon seedlings? A must-read for growers

First, the seed germination rate is low. Seedless watermelon seeds have a relatively thick seed coat and poorly developed embryos, making germination difficult; the germination rate is generally only about 80%. Second, the seedling formation rate is low. Seedless watermelon seedlings have weak growth vigor, grow into seedlings slowly, and have a low seedling formation rate. Third, they require a relatively high ambient temperature. The suitable temperature range for seedless watermelon seed germination is 33 to 35°C, with an upper limit of 42°C and a lower limit of 28°C. This is higher than that of ordinary watermelons.
