Auxin and kinetin interaction in apical dominance

The effects of auxin on the inhibition of lateral buds in decapitated bean plants are enhanced if kinetin is applied together with auxin. The uptake of (14)C-indoleacetic acid by the stumps of decapitated plants is increased in the presence of kinetin and leads to extensive transport of (14)C-indoleacetic acid in the stems. The increased bud inhibition resulting when auxin and kinetin are applied together may be due to greater amounts of auxin reaching the buds, but an alternative explanation is that metabolites are directed from the buds to the point of hormone application.     

Pink disease of Eucalyptus in India

Large scale mortality of Encalyptus tereticornis and E. grandis caused by Corticium salmonicolor in high rainfall locations in India is reported. Symptoms, incidence and epidemiology of the disease and pathogenicity of the fungus are worked out. Suitable alternative species based on performance and field resistance to the discase have been selected. Possibilities of fungicidal control of the disease are explored.
