Uromyces phaseoli, the causal agent of bean rust, suppressed shoot and root growth of three bean cultivars, reducing root weight more than shoot weight. The greatest suppression of root weight was on the cultivar that appeared most susceptible by visual ratings of shoot symptoms. Meloidogyne incognita suppressed shoot and root growth of all test cultivars; root weight reductions differed among ...

Shoot tips and nodal segment explants to Rauwolfia serpentina when cultured on MS medium containing varying concentration of Benzyl adenine purine (BAP) and Benzyl adenine purine in combination with Indole butyric acid (IBA) produced multiple shoots. Maximum multiple shoots (85.6%) were found in static MS medium supplemented with 5.0 mg/ 1 BAP and 0.5 mg / 1 IBA along with 2.5% sucrose and 0.85...

A single plant produces several different types of leaves or leaf-like organs during its life span. This phenomenon, which is termed heteroblasty, is an invariant feature of shoot development but is also regulated by environmental factors that affect the physiology of the plant. Invariant patterns of heteroblastic development reflect global changes in the developmental status of the shoot, such...

The present study demonstrates an efficient protocol for in vitro mass propagation of A. curassavica through direct as well as indirect regeneration. The effect of MS and L2 media supplemented with various concentrations and combinations of growth regulators has been studied. The growth regulators used include BAP and kinetin (cytokinins) and IAA, IBA, NAA and 2, 4-D (auxins). MS media proved b...
