Cytokinin antagonists and antibiotics related to nalidixic acid : effects on Phaseolus and Nicotiana callus tissues

Creator:

Marsden, Katherine E.

Abstract:

The effects of five cytokinin antagonists on the growth of cytokinin-autonomous lines of Phaseolus lunatus cv. Kingston, Phaseolus vulgaris cv. Great Northern, and Nicotiana tabacum cv. Wisconsin 38 callus tissues have been compared. The antagonists tested included four N⁴-substituted 4-amino-2-methylthiopyrrolo[2,3-d]pyrimidines bearing the following N⁴ side chains, 4-n-pentyl- (ms²pnN⁴Prp), 4-n-hexyl- (ms²HxN⁴Prp),...

Interaction of cytokinins and phenethylamines in cell-free enzyme systems and plant callus cultures

Creator:

Abdelnour-Esquivel, Ana

Abstract:

1-Phenyl-3-(2-Thiazoly1)-2-Thiourea (PTTU), has been reported to inhibit dopamine-fi-hydroxylase (a copper-containing enzyme involved in the pathway of biosynthesis of adrenaline in animal systems). In the present study, PTTU has been shown to have cytokinin activity in the tobacco bioassay. The cytokinin activity of PTTU suggested that cytokinin-active N⁶-substituted adenine derivatives might...

Effects of intercropping beans with maize on angular leaf spot and rust of beans

Creator:

Boudreau, Mark Alan, 1958-

Abstract:

Experiments were performed to determine the nature of maize influence on bean disease in additive-type intercrops. Overall effects of intercrops on angular leaf spot (caused by Phaeoisariopsis griseola) in Kenya indicated >23% reductions (P<0.05) in area under the disease progress curve (AUDPC) in two of three season-site combinations. Fertilization tended...
