Reproductive characters in linseed as affected by different levels of nitrogen, phosphorus, and PH

Abstract

The influence of varying levels of nitrogen, phosphorus, and pH on the reproductive characters of flax (Linum usitatissimum) grown m sand cultures was investigated. The fertility of the plants was calculated by taking total ovule number and seeds produced into consideration. The results indicate that heavy application of nitrogen, and to a lesser extent phosphorus, enhanced the formation of flower buds but curtailed the development of flowers and fruits. Fertility level was reduced accordingly. Optimum hydrogen ion concentration for bud, flower, and fruit formation occurred at pH 6. Fertility level was not significantly affected by the pH range. The influence of pH seems to be related to the uptake of nitrogen.
