THE EFFECTS OF N, P, Ca AND Fe DEFİCİENCY IN UNUM USITATISSIMUM L. İN CAMBIAL ACTIVÎTY AND DIFFERENTIATION

Özet

Öz 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.
