The paper presents the results of a study performed to find out the effect of various aspects of post harvesting on the ornamental plants - Phlox drummondii and Iberis umbellata. Seeds of both the plants were germinated in MH solutions with different concentrations of MH at room temperature and cold temperature. Measurements were taken for root length, shoot length, fresh weight and dry weight of seedlings at regular intervals. The relative growth rate (RGR), leaf weight ratio (LWR) and net assimilation rate (NAR) of both plants were calculated for each of the spray treatments with distilled water, 100 ppm MH, 200 ppm MH, 300 ppm MH and 400 ppm MH. The mineral salts like aluminum sulfate, citric acid, salicylic acid, sodium thiosulphate and sodium benzoate were used as part of the preservative solution with MH. Different parameters like fresh weight, transpiration water loss, water uptake and ratio for all the MH concentrations were also calculated and assessment of post harvest shelf was done. The prime aim of the physiological measurements was to determine leaf shoot and root water relations to monitor plant water stress. It was found that the shoot length in seedling of both the plants were maximum for the plants treated with MH solution of 100 ppm concentration. Temperature of solution does not have much effect on the shoot length.
