| Abstract:
Seven Psidium spp., viz. P. chinensis, P. guineese, P. cujavillus, P. molle, P. cattelianum, P. araca and P. friedrichsthalianum were subjected to mound layering. Two months after mounding, there was 100 per cent rooting in shoots of P. chinensis, followed by P. cujavillus (84.44%). Moderate rooting was observed in P. guineese (52.38%) and P. cattelianum (33.33%). Percentage of rooting was less in P. friedrichsthalianum (8.88%), while there was no rooting in P. molle and P. araca. Significantly higher survival (96.66%) was observed in P. chinensis, which was found easy to root and also produced more number of feeder roots. This was closely followed by P. cujavillus and P. guineese. Emergence of new leaves per shoot varied greatly and shoots of P. chinensis produced maximum (8.66) leaves followed by P. guineese (7.0) and P. cujavillus (7.0). Maximum number of primary and secondary roots were found in P. chinensis followed by P. cujavillus. | |
