When cultured under shoot-forming conditions, cotyledons of radiata pine produced more ethylene and carbon dioxide than under non-shoot-forming conditions. Growth (fresh- and dryweights) and shoot formation were enhanced by the accumulatio

Ceryn Evans,Stuart Fox,Chris Taylor bereft of any vegetation. The growing pressure of population — both human and cattle — has accelerated the process of deforestation. The ameliorative power of forests, though known to people who practise shifting cultivation, has failed to be effective due to short cycles of forest regrowth.

Forest Tree Breeding and Mass Cloning for Tree Improvement in Indian Forestryrough clonal banks, seed zones, seed production areas and seed orchards. Outstanding genotypes are cloned true-to-parent only on a small-scale and mostly to aid breeding through methods of vegetative propagation. Genetically improved plants for plantations are, however, required in large numbers. Th
