Root growth consists of two basic processes, cell division and cell elongation. An integral part of the first process is the synthesis of deoxyribonucleic acid (DNA). DNA biosynthesis was studied in primary roots of Zea mays through incorporation of

Internode growth of vegetative Xanthium plants was studied at various levels on the stem with application of the plastochron index. The bottom internodes were of small size and they displayed small rates of growth. Both, the size of the internodes an

When Xanthium lamina width is plotted versus leaf length during the entire period of growth, a straight line is obtained representing an allometric relationship with a regression correlation coefficient of 0.9973 a lamina width to length ratio of 0.5

Division and growth of chloroplasts was studied during leaf development of Xanthium pensylvanicum at various stages of development represented by the leaf plastochron index.Between leaf plastochron indices -1.00 and 2.56 chloroplast division was obse

One application of gibberellic acid (GA3) to Xanthium shoots resulted in an initial large stimulation, followed by inhibition, of internode elongation. After presumed translocation of the hormone from the locus of its application to the stem apex sev

Petiole development and formation of xylem vessels have been investigated in Xanthium leaves from early ontogeny to maturity. Kinetics of growth was presented in terms of absolute and relative elemental rates of elongation. The process of vasculariza
