SUMMARY Developmental constraints have been proposed different characteristics of microsporogenesis, only cell to interfere with natural selection in limiting the available wall formation appeared as constrained. We show that set of potential adaptations. Whereas this concept has constraints may also result from biases in the correlated long been debated on theoretical grounds, it has been occurrence of developmental steps (e.g., lack of successive investigated empirically only in a few studies. In this article, cytokinesis when wall formation is centripetal). We document we evaluate the importance of developmental constraints such biases and their potential outcomes, notably the during microsporogenesis (male meiosis in plants), with an establishment of intermediate stages, which allow emphasis on phylogenetic patterns in Asparagales. Different development to bypass such constraints. These insights are developmental constraints were tested by character discussed with regard to potential selection on pollen reshuffling or by simulated distributions. Among the morphology.

The Potential of South African Indigenous Plants for the International Cut flower Trade ⁎ E.Y
Available online at www.sciencedirect.com South African Journal of Botany 77 (2011) 934–946 www.elsevier.com/locate/sajb The potential of South African indigenous plants for the international cut flower trade ⁎ E.Y. Reinten a, J.H. Coetzee b, B.-E. van Wyk c, a Department of Agronomy, Stellenbosch University, Private Bag, Matieland 7606, South Africa b P.O. Box 2086, Dennesig 7601, South Africa c Department of Botany and Plant Biotechnology, University of Johannesburg, P.O. Box 524, Auckland Park 2006, South Africa Abstract A broad review is presented of recent developments in the commercialization of southern Africa indigenous flora for the cut flower trade, in- cluding potted flowers and foliages (“greens”). The botany, horticultural traits and potential for commercialization of several indigenous plants have been reported in several publications. The contribution of species indigenous and/or endemic to southern Africa in the development of cut flower crop plants is widely acknowledged. These include what is known in the trade as gladiolus, freesia, gerbera, ornithogalum, clivia, agapan- thus, strelitzia, plumbago and protea. Despite the wealth of South African flower bulb species, relatively few have become commercially important in the international bulb industry. Trade figures on the international markets also reflect the importance of a few species of southern African origin. The development of new research tools are contributing to the commercialization of South African plants, although propagation, cultivation and post-harvest handling need to be improved. A list of commercially relevant southern African cut flowers (including those used for fresh flowers, dried flowers, foliage and potted flowers) is presented, together with a subjective evaluation of several genera and species with perceived potential for the development of new crops for the florist trade. -
