EFFECT OF CALTURE SUBSTRATE AND DISBUDDING ON THE GROWTH AND FLOWERING OF CARNATION

Abstract

The experiment was carried out in college of agric. Baghdad Univ. during 2001, 2002 seasons, to study the effect of (7) different culture substrates on the growth and flowering of normal and disbudded plants. The results indicated that, disbudded plants grown in different mixtures of substrate increased both stem length, dry weight of flowers, and the contents of leaves and flower stems from N , P and K. On the other side number of flowers, dry weight of flower stem were increased in budded plants grown in different substrate. In most cases, the best substrate for carnation was peatmoss which resulted in increasing total number of flowers / plant and calcareous soil which produced the flower stem. Generally, peatmoss, mixture of clay + peatmoss or sand + peatmoss were the favorable substrate for the growth of carnation plants.
