dc.description.abstract
The aim of this work was the establishment of embryogenic calli and cell suspensions from different explants and cultivars ofweeping lovegrass, Eragrostis curvula (Schrad.) Nees, to be used as targets for biolistic transformation. Calli were initiated from immature inflorescences, seeds, embryos, leafbases and root tips. Modified MS medium (Murashige and Skoog, 1962) was used for calli induction and proliferation. Cell suspensions were established and maintained in AAF medium (Wang et al., 1993). Morphogenic calli, embryogenic cell suspensions of moderate growth rate - consisting mainly of compact proembryogenic cell c1usters- and green plants were obtained from all the explants and cultivars assayed, except root tips. Both, explant and genotype were very important factors to be considered in order to obtain a morphogenic response and to establish cell suspensions from this grass. The statistical analysis detected interaction between both factors, explants and genotypes. Immature inflorescences were the best source of explant and Kromdraai was the cultivar that showed the best morphogenic response (expressed as the percentage of calli/explant and the percentage of calli with green spots -every green spot developed into green plants-) with inflorescences, embryos and leafbases. For Morpa and Don Pablo embryos as explants were less responsive than seeds and leafbases. There were no differences in leafbases for all the three cultivars analysed.
