Effects of Different Stock-grown Containers on Growth of Black Wattle (Acacia mearnsii) Seedling

  • Received Date: 1991-10-07
  • Seedling height, collar diameter, root growth capacity, net accumulation and distribution of dry biomass, and water-content in different medium layer are related to the material, structure and volume of a seedling container. The paper container adhibitted by a thinner polythene film has the features of faster water penetration and lower capacity of water conservation as compared to the normal polythene container. The paper container specially for crops has a smaller volume and its medium goes dry easily because of faster penetration. Seedling grown in paper container for root growth capacity is similar to that grown in polythene container, but for seedling height, collar diametre and accumulation of net dry biomass, the former is superior to the latter. The inversive triangle type occurred in distribution pattern of net dry biomass of seedling grown in paper container ranked from leaf-stem-root, which improves seedling growth, and the dumbbell type in that of seedling grown in polythene container, which inhibites seedling growth of the above-ground part. The paper container could be considered as one of the new type container which is suitable to raise vigorous black wattle stocks.

Abstract: Seedling height, collar diameter, root growth capacity, net accumulation and distribution of dry biomass, and water-content in different medium layer are related to the material, structure and volume of a seedling container. The paper container adhibitted by a thinner polythene film has the features of faster water penetration and lower capacity of water conservation as compared to the normal polythene container. The paper container specially for crops has a smaller volume and its medium goes dry easily because of faster penetration. Seedling grown in paper container for root growth capacity is similar to that grown in polythene container, but for seedling height, collar diametre and accumulation of net dry biomass, the former is superior to the latter. The inversive triangle type occurred in distribution pattern of net dry biomass of seedling grown in paper container ranked from leaf-stem-root, which improves seedling growth, and the dumbbell type in that of seedling grown in polythene container, which inhibites seedling growth of the above-ground part. The paper container could be considered as one of the new type container which is suitable to raise vigorous black wattle stocks.
