Abstract:
The present investigation effect of varying levels of pH and preservatives on basal cut of spike in tuberose was carried out at laboratory, Department of Floriculture and Landscape Architecture, College of Agriculture, IGKV Raipur (C.G.) during two consecutive years i.e. years 2020-21 and 2021-22. The experiment was designed in a completely randomized design in factorial arrangement with three levels of preservatives viz., citric acid (100 ppm), aluminum sulphate (100 ppm) and 8-HQC (100 ppm), three levels of basal cut of spike viz., no cut, daily cut and alternate day cut, three levels of pH viz., distilled water, pH-4 and pH-5. The results revealed that the 8-HQC, alternate day cut of the basal part of the spike and pH 4 recorded a significantly maximum number of opened florets at a time per spike as well as the diameter of basal florets (mm) and vase life (days) and minimum physiological loss in weight (PLW %) was recorded in 8-HQC, alternate day cut of the basal part of the spike at pH 4.
