I. Environmental Requirements for Green Onion Cultivation: 1. Temperature: Green onions are cold-tolerant crops, with seeds capable of germinating at temperatures between 2°C and 5°C. The optimum temperature for growth is between 15°C and 25°C, while temperatures exceeding 30°C slow down growth. Exposure to temperatures of 0°C to 3°C for 7 days or 3°C to…
Heat damage often accompanies drought stress, particularly during the hot summer and autumn seasons. Young organs and tissues are particularly susceptible to heat damage. Symptoms include brown patches from sunburn on rolled leaves, yellowing leaf margins resembling “gold edges,” chlorosis near the midrib turning yellow-white, cessation of root growth, and bud-bearing plants with fewer green…
