Chlorophyll a fluorescence as an indicator of heat stress in cotton (Gossypium hirsutum L.)
(Taylor & Francis, 2020)Cotton (Gossypium hirsutum L.) is a major fibre crop that is greatly affected by climatic factors, especially drought and high temperatures. Excessive temperature (above 30 °C) during the reproductive stage (flowering) ... -

Desiccation-induced changes of photosynthetic transport in Parmelina tiliacea (Hoffm.) Ach. analysed by simultaneous measurements of the kinetics of prompt fluorescence, delayed fluorescence and modulated 820 nm reflection
(Elsevier, 2018)Simultaneous in vivo measurements of prompt fluorescence (PF), delayed fluorescence (DF) and modulated reflection (MR) at 820-nm were used to assess effect of short desiccation period (4.5 h) on Parmelina tiliacea lichen. ... -
Effects of the invasive annual grass Lolium multiflorum Lam. on the growth and physiology of a Southern African Mediterranean-climate geophyte Tritonia crocata (L.) Ker. Gawl. under different resource conditions
(North-West University, 2007)Little is known of the physiological and biochemical mechanisms underlying competitive interactions between alien invasive grasses and native taxa, and how these are affected by resource supply. Consequently, this study ...
