Pre treatments of gladiolus cormels to produce commercial yield: II-effect of re-planting the produced corms on the vegeyative growth, flowering and corms production.

摘要

Young gladiolus (cv. Sancerre) cormels require a season of vegetative growth before flowering can be induced. The cormels were presoaked for 24 h in GA3 at 0 or 100 ppm, then the plants were irrigated with different concentrations of magnetized or non-magnetized diluted seawater (0, 5, 10, 15 or 20%). Flowering behaviour and final corm yields raised from replanting of corms produced from the treated plants were investigated during 1998 and 1999 in Alexandria, Egypt. The residual effect of seawater,GA3 and the magnetic system influenced corm size and carbohydrate content, reduced and nonreduced sugars, K and Na in corms that consequently affected the flowering and corm yield produced from replanting of these corms.
