摘要: Abstract The response of passionfruit hybrids ( Passiflora edulis f. × P. flavicarpa cultivar E-23 on seedling rootstocks) to soil moisture was evaluated in a heated glasshouse by irrigating when water pressure potential fell −0.0025, −0.01, −0.14 and −1.5 MPa. Leaf, stem root dry weight, leaf area, vine extension node, flower bud open number were reduced stress. Changes also noted range morphological characteristics. Reductions growth flowering associated with nutrient uptake potential, but not conductance. It concluded that stress may be one the major environmental factors responsible for seasonal fluctuations yields.
