We present new findings on leaf and stomatal apparatus anatomy and ecophysiology of Welwitschia mirabilis Hook.f. that are relevant to survival in the desert. We show that the structure of the stomatal apparatus with thin areas in the guard cell wall

Traditional crops are extremely important for food production in low income, food-deficit countries (LIFDCs) where they continue to be maintained by socio-cultural preferences and traditional uses. Significant potential exists to improve these crops,

Due to chilling sensitivity, minimum night temperatures represent the main constraint in soybean production in South Africa. In vivo quantification of photosystem II (PSII) function by direct chlorophyll fluorescence revealed that dark chilling (8°)

South Africa's large industrial growth has created an obvious need to extend, improve and evaluate air pollution impacts on plants in order to assess present-day and future impacts of air pollutants on crop yields. In order to provide guidelines for

The aim of this study was to quantify the effect of the pollutant, trifluoroacetate (TFA), on growth and photosynthesis of Phaseolus vulgaris (C(3)) and Zea mays (C(4)) in order to elucidate the physiological and biochemical basis of its inhibitory a

The mechanisms involved in the modulation of photosynthesis by drought in non-CAM desert plants have received little attention and were investigated in this study through measurement of chlorophyll a fluorescence (OJIP) transients. We focused on two

Dark chilling affects growth and yield of warm-climate crops such as soybean [Glycine max (L.) Merr.]. Several studies have investigated chilling-stress effects on photosynthesis and other aspects of metabolism, but none have compared effects of whol

The impacts of sulphur dioxide (SO 2 ) pollution on succulents in arid environments are relatively unknown and the few studies that have considered these effects focused primarily on species exhibiting crassulacean acid metabolism (CAM). However, the

In the experiments reported in this paper, we demonstrate how the chlorophyll a fluorescence transient O-J-I-P can be utilised in screening for dark chilling tolerance in large numbers of soybean [Glycine max (L.) Merr.] genotypes. Thirty South Afric
