EFFECT OF WATER STRESS AT DIFFERENT STAGES OF ROSE DEVELOPMENT |
| Author: | D. Chimonidou-Pavlidou |
| Abstract:
Water stress applied at the stage of leaf primordium formation resulted in a delay in the rose production cycle but did not have any negative effects on the quality of the flower shoot or the flower bud. The stage prior to petal initiation was more sensitive. Water stress at this stage affected the quality of flower buds (reduction of the number of well formed petals and of the height of the flower bud). Water stress imposed prior to stamen initiation seemed to be the most damaging on rose development affecting the quantity (up to 70% reduction of production) and the quality of the flowering shoots and buds (reduction on the stem length and fresh weight of the flowering shoot and on the diameter and height of bud as well as the number of well formed petals of the flower bud). Water stress applied after stamen formation and after carpel formation, did not have any negative effect either on the number of flowering shoots that reached the marketable stage, or on the quality of the flowers produced. | |
