Abstract

Water deficit is the most predominant environmental STRESS, limiting plant growth and productivity. However, there are considerable differences in sensitivity to adverse conditions, between or within species. Therefore, improvement of DROUGHT TOLERANCE is suggested as one of the most desirable breeding objectives. This study was conducted to assess differences in STRESS responses, in order to screen drought tolerant GENOTYPEs of Rosa damascena.Plant SURVIVAL, VIGOR and growth components in different GENOTYPEs of Rosa damascena were analyzed. There was a considerable variation for water deficit responses. All of the characteristics including plant VIGOR, SURVIVAL, leaflet number, LEAF AREA, branch number, and the longest branch were found to be significantly different in the drought STRESSed GENOTYPEs, in recovery environment. Also, plant SURVIVAL correlated positively with plant VIGOR, leaflet number, LEAF AREA, branch number, and the longest branch. Positive correlation was also revealed between plant VIGOR and LEAF AREA, leaflet number, branch number and the longest branch. The variation in growth components detected between the GENOTYPEs, and the correlation between different traits, could support a suggestion for improvement of Rosa damascena, towards a capability of growth in semi-arid and arid conditions.
