The effects of N, P, Ca and Fe deficiency in linum usitatissimum L. in cambial activity and differentiation

Abstract

İn the radiai grüwtb inhibition of Linuın nsitatissimura L. The most important material deficient was N folîotved by P and Ca. The least deficient material was found to be Fe. There observed a correlation between the shoot growth and the radiai growth wben compared with the measured lengths of the plants. The phloem and X yleoı differentiation was found to be effeeted by deficiency of ali ions to different extent. The xylem forınation was effected most by the deficiency in P whi!e phloem formation was effected most by the deficiency in Ca and N. The deficiency of P effected the fiber formation most.
