Effects of drought stress and field treatments on seed germination and early growth traits of parental berseem clover seeds
Improving seed resistance to water shortage can enhance forage production and sustainability in arid and semi-arid agricultural lands. This three-year field, laboratory and greenhouse study proposes applying surfactant to effectively prevent the detrimental impacts of severe drought conditionson early plant development. Seeds retrieved from six parental plantsof berseem clover (Trifolium alexandrinum L.) developedunder I100 (100% irrigation water)/I100+s (irrigation water plus surfactant), I75/I75+s and I50/I50+s treatments in the field.
