Abstract
To determine what forms of skeleton weed are present in Western Australia and to map their respective distribution. To determine, on the basis of climatic characteristics, the suitability of various areas within the Western Australian wheatbelt for infestation by skeleton weed. To determine the amounts, viability and dormancy status of seeds produced by field-grown plants during summer and autumn months. To determine the effectiveness of conventional tillage practices in limiting establishment of skeleton weed seedlings. To determine the regularity with which seedling establishment occurs under field conditions and how the probability of establishment is affected by the time of germination. To follow the fates of plants which establish from experimental sowings. To determine patterns of emergence, seedling survival and reproduction of wild radish in dry and wet-sown lupin crops in relation to cultivation and herbicide treatments. To establish the identities of two Western Australian populations of mesquite (Prosopis), by comparison with taxa of known identities, using the technique of starch gel electrophoresis. This information will be: required should biological control of mesquite be attempted.
