Morphophysiology of Potato (Solanum tuberosum) in Response to Drought Stress: Paving the Way Forward

The cultivated potato ( Solanum tuberosum L.) is currently the third most important food crop in world and becoming increasingly to local economies of developing countries. Climate change threatens drastically reduce yields areas where growing season predicted become hotter drier. Modern well known as an extremely drought susceptible crop, which has primarily been attributed its shallow root system. This review addresses this decades old consensus, highlights other, less understood, morphophysiological features likely contribute susceptibility. explores effects on these traits goes discuss phenotypes may be associated with tolerance potato. Small canopies increase harvest index decrease evapotranspiration, open stem-type light penetration, but densely rooted cultivars, water uptake, have all past, largely ignored. While individual studies a limited number cultivars examined phenotypes, they are typically overlooked due consensus that depth only significant cause susceptibility We work, particularly respect morphology, context changing climate, highlight gaps our understanding such work implies.
