Modifications in vapor diffusion resistence of leaves and water relations in barbados cherry plants under water stress Rev. Bras. Fisiol. Veg.
NOGUEIRA,REJANE J. MANSUR C.; MORAES,JOSÉ ANTÔNIO P. V. DE; BURITY,HÉLIO ALMEIDA; BEZERRA NETO,EGÍDIO.
Young sexually and assexually propagated Barbados cherry plants were submitted to water deficit (20 days without irrigation). During this period the accumulation of proline, water potential of branches, osmotic potential, the relative water content of leaves, the leaf diffusive resistance, the transpiration rate and leaf temperature in the cuvette were determined. In addition, photosynthetically active radiation (PAR) and vapor pressure deficit (VPD) were measured in the porometer cuvette. The concentration of proline for both types of plants began to increase on the fifth day without watering, and reached 38.1 times the concentration in the control plants grown from seeds and 26.4 times the concentration in grafted plants on the tenth day without...
