Engineering seeds to resist drought - MIT News
网页2021年7月8日 · MIT researchers have devised a way to protect seeds from the stress of water shortage during their crucial germination phase, and even provide the plants with extra nutrition. Simple and inexpensive, the process could be deployed in arid regions to facilitate agriculture on drought-stressed land.
Down-to-earth drought resistance | Nature Plants
网页2024年4月23日 · It has long been realized that drought resistance can be achieved by multiple traits that are broadly classifiable into three main types: drought escape (by short life duration), drought...
Declining Tradeoff Between Resistance and Resilience of …
网页2024年5月8日 · Resistance and resilience are widely used to characterize ecosystem drought stability. Tradeoff between resistance and resilience have been reported, but its long-term trends remain uncertain at global scale. Based on remotely sensed vegetation indices, we assessed the spatiotemporal dynamics of drought resistance and resilience.
