    EFFECT OF DIFFERENT FLORAL PRESERVATIVES ON POSTHARVEST VASE LIFE OF GYPSOPHILA (Gypsophila paniculata L.) Cv. STAR WORLD UNDER AMBIENT CONDITIONS
    (Sri Konda Laxman Telangana State Horticulture University, Mulugu, Siddipet (Dist.), College of Horticulture, Rajendranagar, Hyderabad-30, 2020-11-16) TALARI SANGEETHA; Dr. D. LAKSHMINARAYANA
    The present investigation entitled “Effect of different floral preservatives on postharvest vase life of gypsophila (Gypsophila paniculata L.) Cv. Star World under ambient conditions” was carried out in the Department of Floriculture and Landscape Architecture Laboratory, College of Horticulture, Rajendranagar, Hyderabad during 2019-2020. In experiment I, effect of sucrose and biocides on postharvest vase life of gypsophila was studied and the results revealed that, among all treatments T9 (sucrose @ 2 % plus 8-HQS @ 200 ppm) recorded the best figures in majority of the parameters viz., water uptake (27.42 g flower-1), transpirational loss of water (22.22 g flower-1), vase life (15.5 days), relative water content (96.38 %), fresh weight (15.9 g flower-1), dry weight (9.4 g flower-1) and water uptake to water loss ratio (1.276) over other treatments and the same treatment registered the lowest optical density of vase solution (0.045 nm) and physiological change in weight (0.82 %) as compared to other treatments, whereas higher water balance was recorded with T8 (sucrose @ 2 % plus 8-HQS @ 100 ppm) (5.24 g flower-1) rather than other treatments. In the experiment, studies on the effect of sucrose and antioxidants on postharvest vase life of gypsophila, T11 (sucrose @ 2 % plus KMS @ 200 ppm) was shown maximum for most of the parameters i.e., water uptake (31.42 g flower-1), transpirational loss of water (35.02 g flower-1), vase life (16.83 days), relative water content (103.14 %), fresh weight (16.8 g flower-1), dry weight (8.7 g flower-1) and water uptake to water loss ratio (1.045) and lowest for optical density of vase solution (0.044 nm) and physiological change in weight (0.82 %) over other treatments, while highest water balance (0.66 g flower-1) was recorded in T1 (sucrose @ 2 %) as compared to rest of the treatments. Third experiment was conducted by taking best holding treatment solution combinations of I and II experiments, among the treatments, T1 (sucrose @ 2 % + 8HQS @ 200 ppm + KMS @ 200 ppm) registered maximum water uptake (27.76 g flower-1), transpirational loss of water (28.90 g flower-1), vase life (16.98 days), relative water content (100.23 %), fresh weight (17.03 g flower-1), dry weight (9.5 g flower-1) and water uptake to water loss ratio (10.95) and minimum optical density of vase solution (0.077 nm) and physiological change in weight (2.60 %). However higher water balance was recorded in T3 (sucrose 2 % + 8HQS 100 ppm + KMS 200 ppm) (-0.42g flower-1) over other treatments.
