Osmoconditioning of seeds of sweet pepper (Capsicum annuum L.)
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: H.A. van de Venter --- Magaretha Mes Institute for Seed Research, Rentia Hoffman --- Magaretha Mes Institute for Seed Research,Germination rate of seeds of sweet pepper (Capsicum annuum L.) cv. Florida Resistant Giant was increased significantly at both 15 °C and 25 °C after osmotic priming for 10 days at 15 °C in solutions of polyethylene glycol. Post-treatment drying... -
Influence of sub-optimal imbibition temperatures on seed vigour and respiration in maize (Zea mays L.)
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: H.A. van de Venter --- , N. Grobbelaar --- ,Germination and coleoptile growth of nine seed lots of maize (representing seven cultivars) were studied at 25°C (constant), 13°C (constant) and also at 7°C (7 days) followed by 25°C. Relative germination response to sub-optimal temperatures reflected relative differences in germination... -
Stimulation and suppression of mineralisation and nitrification in incubated soil
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: K. Agrella --- Department of Plant Production and Soil Science, South Africa P. Boeckx --- Department of Applied Analytical and Physical Chemistry, Belgium A.S. Claassens --- Department of Plant Production and Soil Science, South Africa O. Van Cleemput --- Department of Applied Analytical and Physical Chemistry, BelgiumPriming, induced through the addition of oxidisable organic matter, releases or immobilises nitrogen and other nutrients in the soil. Moisture plays a very important role in priming as it stimulates microbial activity after a dry soil is wetted, especially with... -
Comparison of osmopriming and seed coating with calcium salts for green bean performance under field conditions. I. Cotyledonal cracking
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: T.G. Mazibuko --- , A.T. Modi --- ,Cotyledonal cracking is a physiological disorder, which appears as one or a few transverse fissures across legume seed cotyledons early during seed germination or seedling emergence. The fissures hinder translocation of nutrients to the developing seedling and cause stunted seedling... -
Comparison of osmopriming and seed coating with calcium salts for green bean performance under field conditions. II. Stand establishment, chlorophyll fluorescence and yield
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: T.G. Mazibuko --- School of Agricultural Sciences & Agribusiness, Crop Science Discipline, A.T. Modi --- School of Agricultural Sciences & Agribusiness, Crop Science Discipline,Seed coating is commonly used to supply fungicides and micronutrients to enhance seed quality. The primary reason for using mineral elements in seed priming is to regulate water absorption. Osmopriming and seed coating were compared for their effect on crop... -
Effects of seed priming and water potential on germination of cotton (Gossypium hirsutum L.) and maize (Zea mays L.) in laboratory assays
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: F.S. Murungu --- Department of Agronomy, Faculty of Natural Resources and Agriculture, Zimbabwe P. Nyamugafata --- Department of Soil Science and Agricultural Engineering, Faculty of Agriculture, Zimbabwe C. Chiduza --- Department of Crop Science, Faculty of Agriculture, Zimbabwe L.J. Clark --- , UK W.R. Whalley --- , UKSub-optimal crop emergence and establishment is a problem in crop production owing to low soil moisture. The effects of seed priming (seed soaking) on cotton and maize germination at different water potentials (0, −10 kPa, −100kPa, −200 kPa, −500 kPa... -
Seed mix type but not planting method or seed priming affect grassland restoration outcomes: a greenhouse trial
Item type: Journal Article • Journal: African Journal of Range & Forage Science • Authors: Stuart Demmer --- School of Life Sciences, South Africa Michelle J Tedder --- School of Life Sciences, South Africa Kevin P Kirkman --- School of Life Sciences, South AfricaCommercial seed mixes and various mechanical planting methods have been implemented to overcome barriers to successful restoration of degraded grasslands but their effectiveness in aiding the restoration process has been understudied. Harvested seed must be cleaned of chaff to allow... -
Gibberellic and salicylic acids improve seedling emergence, early growth and some physiological characteristics of Phaseolus vulgaris L. under soil compaction
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: Hamid Reza Eisvand --- Lorestan University, Iran Hadis Nasrollahi --- Lorestan University, Iran Feizollah Shahbazi --- Lorestan University, Iran Mohammad Feizian --- Lorestan University, Iran Donald L Smith --- McGill University, CanadaHeavy soil compaction and crusting adversely affect the percentage and speed of seedling emergence, particularly in dicotyledonous epigeal plants. This study aimed to evaluate ways to cope with this phenomenon in kidney bean through hormonal priming. A factorial experiment was...
