Effect on Quality Characteristics of Tomatoes Grown Under Well-Watered and Drought Stress Conditions
Tomatoes are one of the most nutritionally and economically important crops in New Zealand and around the world. Tomatoes require large amounts of water to grow well and are adversely affected by drought stress. However, few studies have evaluated the physicochemical characteristics of commercial to...
