"Maize, sorghum and pearl-millet are leading C4 cereals for tropical\r\nregions where evaporative demand is high. The transpiration\r\nresponse to high VPD and leaf area of plants grown under different\r\nVPD conditions was compared among species to assess\r\nthe degree of water conservation of these crops and then their\r\npotential fitness to different stress scenarios. Ten genotypes of\r\neach species were grown under moderate (2.2-2.8kPa) and high\r\nVPD (3.9-4.5kPa) conditions till early vegetative (V5-V7) stage\r\nwith no water-limitation. At that stage transpiration was measured\r\nunder elevating VPD (0.9-4.1kPa) in controlled conditions.\r\nAll three species grown under moderate VPD conditions showed\r\na variation in transpiration restriction above 3.0kPa, although the\r\ndecrease in transpiration above 3.0kPa was high in the case of\r\nmaize. Sorghum and pearl-millet grown under high VPD conditions\r\nshowed significant reduction in leaf area whereas maize\r\nshowed trivial differences in leaf area across VPD conditions.\r\nTherefore, under high evaporative demand when soil water was\r\nnot limiting, maize saved water only by restricting water use\r\nduring pre-flowering stages whereas sorghum and pearl millet\r\nbothreduced canopy sizeand transpiration under high VPD.\r\nThe soil moisture thresholds where transpiration declined upon\r\nprogressive water stress imposition did not differ significantly,\r\nregardless of different VPD in the growing conditions. Maize had\r\nalso higher TE than sorghum and millet in the high VPD conditions.\r\nTherefore, water conserved in maize by restricted transpiration\r\nin high VPD condition, probably leading to higher TE, was\r\nsufficiently rewarded to sustain biomass accumulation in water\r\nstress period."^^ .
