Phytochemicals, antioxidant and anti-proliferative activities of Myrtus communis L. genotypes from Tunisia S. Afr. J. Bot. (IF 1.792) Pub Date : 2020-10-20 Islem Yangui; Faten Younsi; Wafa Ghali; Mohamed Boussaid; Chokri Messaoud
Myrtle (Myrtus communis L.) has long been regarded as a medicinal and aromatic plant. The analysis of phenolic and terpenic compounds contained in the leaf extracts of three Myrtle genotypes showed their richness in monoterpene hydrocarbons (48, 32%, 83.77%), flavonols, and hydrolysable tannins. Phenolic profiles and volatile compounds varied significantly among genotypes. All leaves extracts revealed

Honey bees are important pollinators of South African blueberries despite their inability to sonicate S. Afr. J. Bot. (IF 1.792) Pub Date : 2020-10-20 Keanu Martin; Bruce Anderson; Corneile Minnaar; Marinus de Jager
Animal-mediated pollination is an essential ecosystem service on which over a third of the world's agricultural crops depend. Blueberry fruit production is highly dependent on animal pollination and although visited by a range of bee species in their native range and agricultural settings, bumble bees are thought to be their primary native pollinators. Demand for blueberries has increased in recent

Micromorphological, histochemical and ultrastructural analysis of flower secretory structures in two species pollinated by flies (Diptera) of Asclepiadoideae Burnett S. Afr. J. Bot. (IF 1.792) Pub Date : 2020-10-20 Natalia Wiśniewska; Andrzej Gdaniec; Agnieszka K. Kowalkowska
This micromorphological, chemical and ultrastructural study is a continuation of research conducted on fly-pollinated species. The aim of proposed project is to examine the features of floral secretory tissue of stapeliads (Eudicots, Apocynaceae, Asclepiadoideae) and compare them with previously published Bulbophyllum species (Monocots, Orchidaceae, Epidendroideae). The Echidnopsis cereiformis and

Glucose escalates PSII activity, dynamics between anabolic and catabolic pathways, redox and elemental status to promote the growth of Brassica juncea S. Afr. J. Bot. (IF 1.792) Pub Date : 2020-10-21 Husna Siddiqui; Fareen Sami; Andrzej Bajguz; Shamsul Hayat
Glucose (Glc), a monosaccharide, accumulates in plants as a minor product of photosynthesis as well as a breakdown product of sucrose. Glucose regulates various physiological processes in plants; therefore, the present experiment was carried out to assess its role in mustard plants. Seeds of Brassica juncea were sown into pots filled with soil and farmyard manure. Glc treatments were provided as a

Effects of exogenous application of five antioxidants on vigour, viability, oxidative metabolism and germination enzymes in aged cabbage and lettuce seeds S. Afr. J. Bot. (IF 1.792) Pub Date : 2020-10-22 Ademola Emmanuel Adetunji; Sershen; Boby Varghese; Norman Pammenter
Ageing induces modifications capable of compromising seed vigour and viability. This study investigated the effects of exogenous application of five antioxidants: ascorbic acid (AA), gallic acid (GA), reduced glutathione (GSH), trolox and glycerol, on physical and biochemical lesions induced by controlled deterioration (CD) in Brassica oleracea (cabbage) and Lactuca sativa (lettuce) seeds. The antioxidants

Effects of foliar selenium application on growth and rhizospheric soil micro-ecological environment of Atractylodes macrocephala Koidz S. Afr. J. Bot. (IF 1.792) Pub Date : 2020-10-22 Wuxian Zhou; Yuanyuan Duan; Yajuan Zhang; Hua Wang; Donghai Huang; Meide Zhang
Atractylodes macrocephala (A. macrocephala), a famous medicinal herb in China, is widely cultivated and consumed in China with various beneficial effects. Numerous studies have shown that selenium (Se) plays an important role in promoting plant growth, although Se has not been considered an essential element for higher plants. The objectives of this research were to determine the effects of foliar

Comparative chemical profiling and antimicrobial activity of two interchangeably used ‘Imphepho’ species (Helichrysum odoratissimum and Helichrysum petiolare) S. Afr. J. Bot. (IF 1.792) Pub Date : 2020-10-30 Khotso Serabele; Weiyang Chen; Sidonie Tankeu; Sandra Combrinck; Clinton G.L. Veale; Sandy van Vuuren; Sushil K. Chaudhary; Alvaro Viljoen
Helichrysum petiolare and Helichrysum odoratissimum, collectively known as ‘Imphepho’, are popular medicinal herbs that are indigenous to South Africa. The species are used interchangeably to relieve gastrointestinal and respiratory conditions, fever and urinary tract infections, implying that they produce antibacterial compounds. Although these herbs are sold in informal markets, they have not been
