Effect of potting media on the growth of Hopea odorata rooted cuttings in the nursery

Aminah H., . and Lee S. S., . and Chong W. S., . and Lapeyrie F., . (2003) Effect of potting media on the growth of Hopea odorata rooted cuttings in the nursery. [Proceedings Paper]

Six types of potting substrates mixed in the ratio of 1: 1 were tested as potting media for Hopea odorata i e sand:coconut husk sand:peat gro sand:rice hulls soil:coconut husk soil:peat gro and soil:rice hulls Rooted cuttings of H. odorata were used as test plants and half of the cuttings were inoculated with a mycorrhizal fungus Pisolithus tinctorius strain Pt 441 At harvest after five months no P tinctorius ectomycorrhizas were found on any of the inoculated co cuttings Plants raised in soil:peat gro mixture were significantly better than those grown in the other potting media for all the variables measured stem diameter shoot height and shoot dry weight Plants grown in soil:peat gro mixture were 58 26 and 105 greater in height diameter and shoot dry weight respectively compared with those grown in soil:rice hulls mixture which is the potting medium normally used in the Forest Research Institute Malaysia FRIM nursery. Plants grown in sand:reat gro mixture performed as well as plants grown in soil:rice hulls mixture indicating that sand:peat gro mixture would be a good substitute for the present potting medium used at the FRIM if soil is unavailable. Generally plants grown in potting media containing sand with the exception of where peat gro was added performed poorly with the poorest growth being observed in plants grown in sand:coconut husk mixture.

Abstract

Six types of potting substrates mixed in the ratio of 1: 1 were tested as potting media for Hopea odorata i e sand:coconut husk sand:peat gro sand:rice hulls soil:coconut husk soil:peat gro and soil:rice hulls Rooted cuttings of H. odorata were used as test plants and half of the cuttings were inoculated with a mycorrhizal fungus Pisolithus tinctorius strain Pt 441 At harvest after five months no P tinctorius ectomycorrhizas were found on any of the inoculated co cuttings Plants raised in soil:peat gro mixture were significantly better than those grown in the other potting media for all the variables measured stem diameter shoot height and shoot dry weight Plants grown in soil:peat gro mixture were 58 26 and 105 greater in height diameter and shoot dry weight respectively compared with those grown in soil:rice hulls mixture which is the potting medium normally used in the Forest Research Institute Malaysia FRIM nursery. Plants grown in sand:reat gro mixture performed as well as plants grown in soil:rice hulls mixture indicating that sand:peat gro mixture would be a good substitute for the present potting medium used at the FRIM if soil is unavailable. Generally plants grown in potting media containing sand with the exception of where peat gro was added performed poorly with the poorest growth being observed in plants grown in sand:coconut husk mixture. This experiment demonstrated that the growth of H odorata was best when peat gro was incorporated into the potting medium.
