| Abstract | ||||
| The present study was done at Antoniades Research Branch, Horticulture Research Institute, A.R.C. Alexandria, Egypt, during the two successive seasons of 2018 and 2019. The bacterial studies were done at Ornamental, Medicinal and Aromatic Plant Diseases Research Department, Plant Pathology Research Institute. The aim of this work was to evaluate the ability to use citric acid at (100,200 and 300 ppm ) , hydrogen peroxide (H2O2) at (5, 10 and 20 ppm) , 8-hydroxyquinoline sulphate ( 8-HQS ) at )50,100 and 200 ppm ( and tricloroisocyanuric acid ( TICA ) at )5, 10 and 20 ppm ( as holding solution on reducing bacterial decay and prolonging the vase life of cut Asparagus densiflorus shoots. The highest significant increase in vase life was obtained after application of TICA at 5 ppm which was 15.78 and 15.56 days in the first and second season respectively while the vase life of control treatment was 7.11 and 7 days in both seasons respectively. Also this treatment recorded the highest significant increase in final water uptake, shoot fresh weight/ shoot dry weight ratio and chlorophyll a & b content. On the other hand, this treatment caused decrease in the loss of shoots fresh weight and the number of bacterial colonies. | ||||
