expanding the breeding program ( Das and Bhagobaty, 2010 ). Therefore, the germplasm appraisal using different biochemical parameters affecting tea quality is essential for selecting desirable varieties. In recent years, many germplasm appraisal methods

SURESTEM plant growth modifier, applied in foliar sprays at 80.0 g ai/H to regrowing stems following rose stem harvest, increased Royalty variety hybrid tea rose stem number and length and improved stem quality. Stem numbers per harvest were increased in Samantha and Kardinal variety roses, but there were no changes in stem quality or stem length. For rose stems harvested on a growth cycle basis, excellent stem number increases were obtained when SURESTEM was applied about 7 days after 90% of the stems had been harvested. The best time of application was affected by temperature and light conditions in the greenhouse, by natural photoperiod in the absence of artificial lighting, and by stem harvest practices of the growers. The best time of application for plants managed on a continuous stem harvest system has not yet been determined. Commercial producers of long-stem roses are evaluating SURESTEM under an EPA Experimental Use Permit issued April 7, 1992. The EUP program and label also permits the evaluation of SURESTEM on other ornamental crops grown for cut stem production in greenhouses.
