               Abstract:

               Performance  of  floricultural  crops  against  diverse  climatic  conditions  and  preservatives
               solutions needs to be standardized for strengthening local cut flower industry. In this research
               work performance of four different exotic gladiolus cultivars was evaluated under climatic
               conditions  of  South  Punjab  Pakistan.  Study  was  consisting  of  experiment  I,  evaluation  of
               growth under field conditions and experiment II, vase life evaluation using locally available
               preservatives. Data of different morphological, physiological, biochemical vase life attributes
               was  recorded.  Significant  effect  of  growing  conditions  was  observed  on  growth  and
               physiological  attributes  of different  gladiolus cultivars.  Green Star showed increased plant
               height, stem diameter, chlorophyll a, chlorophyll b and carotenoid, catalase, guaiacol peroxide,
               SOD, Photosynthetic rate (52.25%), transpiration rate, stomatal conductance as compared to
               local  cultivar.  In  case  of  preservatives  sugar  along  with  lemon  juice  preserved  spikes  for
               maximum days 8 in Chinan. Consequently, gladiolus cultivars exhibited difference in growth
               and vase life providing evidence that response of different cut flowers to diverse climates and
               preservative can be evaluated for application in floriculture industry.
