Paper-chromatogramed extracts of bleeding sap from grapevines treated with (2-chloroethyl)trimethylammonium chloride (CCC) contained higher levels of substances with cytokinin activity than did untreated plants. With the chromatographic solvent used, CCC was unlikely to interfere with the expression
Six-year-old cloned Betula pubescens Ehrh. trees, grown outdoors at 65 degrees 01' N, were cut on six dates during the growing season to study coppice shoot development in relation to root-produced cytokinin-like compounds. Bleeding sap was collected over timed intervals for two days after cutting,
Lamprocapnos spectabilis (L.) Fukuhara is a perennial plant species valued in the horticultural, cosmetic, and pharmaceutical markets. To date, however, there were no studies on tissue culture systems in this species when adjusted from non-meristematic explants. The aim of this study is to
With two extraction procedures differing in the very first extraction steps two cytokinins from a total amount of 180 kg sunflower leaves could be isolated. One of these cytokinins is identified as zeatin by Rf values, UV absorption, melting point of its picrate and its biological activity. The same
