Abstract

This work was conducted to establish the relationship between microspore developmental stage and length of the floral bud in glasshouse-grown Sturt’s desert pea, a native Australian legume. The stages of microspore development were segregated into tetrad, early-uninucleate, mid-uninucleate and late-uninucleate. The results showed that there was a strong relationship between microspore developmental stage and floral bud length. The tetrad stage lasted longer than early-, mid- or late-uninucleate stages. The attempted induction of androgenesis in Sturt’s desert pea using anthers from floral buds with similar size, as in the present work, was unsuccessful. This indicated that other factors, such as medium composition, plant hormones, pre-treatment and environmental conditions, also need to be optimised in addition to appropriate microspore developmental stage.
