Does limited underground water storage make plants less susceptible to drought?(图)
limited underground water storage plants less susceptible drought
2019/10/23
You might expect that plants hoping to thrive in California's boom-or-bust rain cycle would choose to set down roots in a place that can store lots of water underground to last through drought years.B...
Drought-stricken areas anxiously await the arrival of rain. Full recovery of the ecosystem, however, can extend long past the first rain drops on thirsty ground.According to a study published August 1...
