SENSITIVITY OF PREGERMINATED PEPPER SEED TO LOW TEMPERATURES.

Type of article: Article

Summary

THE EFFECT OF STORAGE OF PREGERMINATED PEPPER SEED (CAPSICUM ANNUUM L., CV. HUNGARIAN WAX) AT 273 K (0C) FOR 2 TO 4 DAYS AND 278 K (5C) FOR 4 TO 21 DAYS ON TOTAL PERCENT EMERGENCE, TIME TO 50% EMERGENCE (T50), AND TISSUE VIABILITY WAS EXAMINED. AN EMERGENCE ASSAY AT 298-293 K (25-20C) SHOWED THAT ONLY DRY SEED AND SEED HELD AT 273 K FOR 4 DAYS WERE SLOWER IN EMERGING THAN FRESH PREGERMINATED SEED. EMERGENCE ASSAYS AT 288-283 K (15-10C) SHOWED THAT ALL STORAGE TREATMENTS EXCEPT 278 K FOR 4 DAYS RESULTED IN SLOWER SEEDLING EMERGENCE. DRY SEED TOOK TWICE AS LONG TO EMERGE AS FRESH PREGERMINATED SEED AT 288-283 K. PERCENT EMERGENCE DATA AND TETRAZOLIUM CHLORIDE ASSAY RESULTS SUPPORTED THE T50 DATA.
