Effects of watering regime on the morphological, physiological and functional traits of seedlings of cacao provenances under screen house conditions

In the present study, morphological and physiological responses of cocoa provenances to watering regimes under screen house conditions implications measured variables as drought tolerance strategy in Theobroma was discussed. A 4 by 3 factorial scheme involving four cacao (well at full field capacity, 60 40% capacity: 1.5, 0.9 0.6 L/plant each event) genotypes evaluated are PA 150 Series (the elite varieties), F3 Amazon Amelonado. Observations were made on traits seedlings affected regimes. The deployed rank performance following nursery desiccation studies. Data root shoot biomass, water use, stomatal conductance, proline, soluble carbohydrate leaf chlorophyll concentrations collected. results showed that zone moisture status characteristics provenances. Differences obtained densities its conductance gases, chlorophyll, proline carbohydrates among imposed. Cacao also differed their characters. imposed scenarios elicited differences evaluated. Most driven provenances, appeared have played important roles deficit stress mechanisms cacao. Seedlings had better vigour growth when grown 100 60% capacity compared with FC. Adequacy soil promotes functions tested. morpho-physiological statistically superior well watered situations (100% FC) confirmed cannot withstand for It is recommended (FC) 70% FC (mild stress) will ensure production vigorous nursery.
