Wagner M. | Medina G. | Laborem G.

The main purpose of the study was to determine the amount of aminoacid "Prolina" in the leaf of Valencia orange (Citrus Sinensis) in relation with the water available in a soil Mollisols (Fluventic Haplustolls); the results are from the cycles 1993 and 1994. We work in orange Valencia graft on: madarin orange, Cleopatra (Citrus Reshssi), lemon Volkameriano (Citrus Volkameriano) and Citrange Carrizo (Poncirus trifoliata). The soil was a Fluventic Haplustolls, sandy loam the experimental design was aleatory, the irrigation was each 5-10 and 15 days. There is a significant difference at 0.01 P between different irrigations and the amount of proline during February and April 1994. In February Citrus Volkameriano presents the biggest amount of proline 15.83 micrograms/gr fresh material when the plants were under condition of moderate (10 days) to extreme (15 days) deficits of water. During April the citrus Volkameriano presents the proline in 89.20 microgram/gr fresh material in condition of moderate (10 days) deficit of water. The citange Carrizo present the lowest content of proline 5.75 microgram/gr fresh material under conditions of extreme hydric deficit.
