Diurnal Photosystem II Photochemical Efficiency and Biomass Partitioning in Acacia mellifera and Acacia laeta Seedlings Under Drying Soil

Abstract

Aim of study: The study aimed to assess the impact of drying soil on diurnal photochemical efficiency of photosystem II and biomass partitioning of the seedlings of Acaia mellifera (Mf) and Acacia laeta (Lt).

Acacia senegal and Acacia mellifera: A novel mutant with a reduced dormancy period through silver nanoparticles

“…It is common in the arid African savanna. It grows on hard clay soil in the central parts of Sudan and extends westward to near Lake Chad [15]. Acacia mellifera has the ability to x nitrogen, which is thought to improve soil fertility and, ultimately, herbage quality under canopy and beyond [16].…”

Photochemical efficiency and growth of two provenances of Acacia senegal )gum arabic( tree seedlings under drying soil

“…Concurrent understanding of young seedling growth and capacity of photosynthetic machinery under water stress conditions likely provides us information to select the appropriate genotypes for plantation in dry lands. It has been reported that the assessment of plant morphogenesis at early stages of life provides necessary indicators for subsequent performance of species under arid environments (Johnson, 1980;Kramer and Boyer, 1995;Merine et al, 2015;Siam and Abdalkreem., 2019). In an ecophysiological context, the measurement of chlorophyll fluorescence tends to be a useful technique in quantification the effect of stresses on photochemical efficiency of PSII (Klughammer and Schreiber, 2008;Lambers et al, 2008).…”
