dc.description.abstractAn experiment titled “ Suitability studies of Dracaena as cut foliage” was conducted in the Experimental Farm and Laboratory, Department of Horticulture, Assam Agricultural University, Jorhat, 2018-2019 with the objective of evaluating the performance of different species/varieties of Dracaena for growth and yield attributes and to study the effect of pulsing solutions on the post harvest life of cut greens of ten different species/varieties of Dracaena namely - three varieties of D. Sanderiana( Lucky Bamboo “Gold”,“Victory”and“Green” ),D.thalioides, D. reflexa “Green” , D. marginata “Mahatma”, D. fragrans “Massangeana” , D. compacta, D compacta “ Purple” and D deremensis“Janet Craig” . The experiment was laid out in 50% agroshade net house inrandomised block design with 3 replications and observations were recorded after one year of planting. Using the cut foliage of Dracaena sanderiana “Victory” in 15 different pulsing treatment combinations, the best five were selected, viz., BAP 25 ppm+ LHB @ 0.25%, Chlorine + Sucrose 10% , BAP 50 ppm+ LHB @ 0.25% Chlorine + Sucrose 10%, BAP 50 ppm + LHB @ 0.50 %. Chlorine + Sucrose 10%, BAP 25 ppm+ BP 0.50% + Sucrose 10%, BAP 50 ppm+ BP 0.25%+ Sucrose 10%. D. fragrans“Massangeana” showed the best performance in terms of growth characters, namely plant height and spread (121.26 cm and 75.23 cm, respectively), leaf breadth (9.46cm), number of leaves per plant (39.66) and leaf longevity (26.7 days). This was followed by D. deremensis which had longest leaves (54.2cm), highest leaf area (1225.03 sq.cm) and consumer preference. D. reflexa “Green” reported the lowest leaf production interval (8.1 daysThe chlorophyll content is highest in D. sanderiana“Gold”(0.85mg g -1 FW). The visual plant quality rating was highest for 4 species- D. sanderiana Gold, D. sanderiana Victory, D. sanderiana Green and D. compacta. D. compacta“Purple” showed the highest vase life (15.93 days), followed by D.sanderiana Green (15.27 days). D.deremensis recorded the highest relative leaf water content (72.31%). The physiological loss in weight was lowest for Dracaena reflexa Green (6.34%). Among the pulsing solutions, BAP 25 ppm+ BP 0.50% + Sucrose 10% recorded the highest vase life (14.40 days), followed by BAP 50 ppm+ LHB @ 0.50% Chlorine + Sucrose 10% (13.9 days). BAP 50 ppm+ BP 0.25%+ Sucrose 10% showed the highest relative leaf water content (49.41%) and the physiological loss in weight was lowest for P2-BAP 50 ppm+ LHB @ 0.25% Chlorine + Sucrose 10% (13.33%).en_US
