Comparative studies of the germination of seed and the emergence and development of seedlings of some native and introduced plant species : With special reference to the re vegetation of depleted tussock-grasslands : A thesis submitted for the degree of Master of Agricultural Science and Honours in Field Husbandry, University of New Zealand

Abstract

Species of forage plants were chosen, which appeared to be worthy of study with regard to their use in revegetation work, particularly in the drier areas of the montane tussock grasslands. Some of the species were of exotic origin and some were indigenous to the tussock grasslands of New Zealand. The aims of the study: 1. To compare the germination of seed from the species selected, under laboratory conditions, and the germination and emergence resulting from field sowings. 2. To compare the seedling development of the selected species, with particular reference to their root development when all species were grown under similar conditions. 3. To attempt to relate the results obtained, to the problem of revegetation of depleted tussock grasslands in low rainfall areas in the South Island.
