Water availability has frequently been linked to seasonal leaf display in seasonally dry ecosystems, but there have been few ecohydrological investigations of this link. Miombo woodland is a dominant seasonally dry tropical forest ecosystem type in southern Africa; however, there are few data on...

Carapa wohllebenii is described as a new tree species from the Democratic Republic of Congo, Rwanda, and Burundi. Its affinities to Carapa grandiflora are discussed. It differs in a number of morphological features; the most prominent being the oblanceolate-oblong leaflets with distinctly mucronate ...

Drought stress is one of the key plant stresses reducing grain yield in cereal crops worldwide. Although it is not a breeding target in Northern Europe, the changing climate and the drought of 2018 have increased its significance in the region. A key challenge, therefore, is to identify novel...

Natural forests are an important source of livelihood for various communities. Yet economically important fruit tree species endemic to sub Saharan Africa e.g. Sclerocaryea birrea (Marula) are critically endangered due to over-exploitation and climate change. Effective conservation, management and...

The results of research into the water relations and irrigation requirements of lychee are collated and reviewed. The stages of plant development are summarised, with an emphasis on factors influencing the flowering process. This is followed by reviews of plant water relations, water requirements,...

Abiotic factors vary along altitudinal gradients, and this may influence plant morphology, physiology and function. This study aimed to test the hypothesis that leaf δ¹³C-a common proxy for water use efficiency-was indirectly influenced by morphological adjustments with changing climatic factors...

The Malagasy genus Capurodendron currently accommodates 26 described species and is the largest genus of the family Sapotaceae in Madagascar. These species are frequently logged because of their valued hardwood, which potentially puts them at risk of extinction. Species-level identifications are...

Glinus is a small genus of Molluginaceae with 8-10 species mostly distributed in the tropics of the World. Its composition and evolutionary relationships were poorly studied. A new molecular phylogeny constructed here using nuclear (ITS) and chloroplast (rbcL, trnK-matK) markers confirmed the...

Background and Objective: Gamma rays at different doses have been used to induce mutation in several species. The objective of the study was to determine mutant lines with improved agronomic traits. Materials and Methods: Seeds of soybean variety 'Jenguma' were irradiated with gamma rays at 150,...

Water stress is the most important factor limiting early survival and growth of seedlings in arid and semi-arid zones. Many woody species develop adaptive mechanisms in response to water stress. This study assesses survival rate, growth and dry matter distribution in response to water stress in...
