Bio-stimulatory properties in seeds of plants from the families Caryophyllaceae and Fabaceae with application potential in agriculture
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: J.C. Pretorius --- , South Africa A. Du Plessis --- , South Africa E. van der Watt --- , South AfricaA comparative investigation into the bio-stimulatory activity of seed suspensions from two South African plant species belonging to each of the families Caryophyllaceae and Fabaceae were conducted using ComCat®, a commercially available bio-stimulant, as a positive control. These included Acacia... -
Low genetic diversity and high genetic differentiation among severely fragmented populations of the critically endangered tree Talbotiella gentii (Fabaceae)
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: D Dompreh --- School of Biological Sciences, UK MD Swaine --- School of Biological Sciences, UK A Price --- School of Biological Sciences, UKThe genetic diversity among 17 populations (including 10 newly discovered) of Talbotiella gentii (Fabaceae, Caesalpinioideae), a rare tree species endemic to Ghana, was assessed using random amplified polymorphic DNA (RAPD). A total of 80 polymorphic bands were generated from eight... -
Assessing legumes indigenous to South Africa, Lesotho and Swaziland for their pasture potential
Item type: Journal Article • Journal: African Journal of Range & Forage Science • Authors: Marike Trytsman --- Agricultural Research Council–Animal Production, South Africa Elizabeth L Masemola --- Agricultural Research Council–Animal Production, South Africa Francuois L Müller --- Agricultural Research Council–Animal Production, South Africa Frikkie J Calitz --- Agricultural Research Council–Central Office (Biometry Services), South Africa Abraham E van Wyk --- Department of Plant and Soil Sciences, South AfricaIn contrast to the exploration and use of southern African grass plant genetic resources over the past century, only a few indigenous legume species are currently used as forages, notwithstanding the vast untapped legume diversity available in southern Africa. The... -
Low constant temperature drying can be a satisfactory method to determinethe moisture content of impermeable seed coated species
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: Ganesh K Jaganathan --- University of Shanghai for Science and Technology, China Jiajin Li --- University of Shanghai for Science and Technology, China Baolin Liu --- University of Shanghai for Science and Technology, ChinaThe International Seed Testing Association (ISTA) recommends two methods for seed moisture content determination: high constant temperature drying, carried out at 130 °C for 1, 2, 3 or 4 hours, and low constant temperature drying, carried out at 103 °C... -
Foraging behaviour of scatter-hoarding gerbils (Gerbilliscus (Gerbillurus)) influences seed fate and dispersal for key plant species in the Namib Desert
Item type: Journal Article • Journal: African Zoology • Authors: Saima D Shikesho --- Gobabeb-Namib Research Institute, Namib Naukluft National Park, Namibia Eugene Marais --- Gobabeb-Namib Research Institute, Namib Naukluft National Park, Namibia Jeremy J Midgley --- University of Cape Town, South AfricaHairy-footed gerbils (Gerbilliscus (Gerbillurus) spp.) in the Namib Desert play a dual ecological role as both seed dispersers and predators, a behaviour typical of scatter-hoarding species. The fate of seeds following their removal by these gerbils, whether consumed immediately or...
