Subject:
Musa; bananas; climate change; drought; food crops; heat; heat stress; rain; stress management; subtropics
Abstract:
... With the changing climate, crops are facing mounting threats from multiple abiotic stresses, and studies that assess the response of plants to combinations, rather than to individual, abiotic stresses are becoming increasingly relevant. Bananas are one of the most globally important and popular food crops and their production is threatened by increasing heat and diminishing rainfall in tropical an ...
