The virescent cotton (Gossypium hirsutum) mutant described here differs from normal cultivated cotton by a single mutation in the nucleus. The mutant exhibits nuclear control of chlorophyll and carotenoid development. Young leaves are distinctly yellow and become green with age. There is no unusual photometabolism of (14)CO(2) or (14)C-acetate in this mutant. It is probable that the nuclear vir...

A mild method was developed to remove cyanogens from cassava leaves that involved three consecutive steps (1) pounding, (2) standing for 2h in the sun or 5h in the shade in the tropics and (3) washing three times in water. Four cassava cultivars were used and the mean residual total cyanide content after steps 1, 2 and 3 was 28%, 12% and 1%, respectively. The pounded cassava leaves retained the...

In this study, morphological and physiological effects of the stress with the UV-C rays on the industrial Atlanta type beans (Phaseolus vulgaris L. Cv, Atlanta) were analyzed. The plants were raised in an automated green house with the ecological conditions. The plants were grown in the green house with UV-C lamb (250) for 6, 8, 10, 12 and 14 days. After which their root lengths and seeding hei...

The trebouxiophycean genus Phyllosiphon contains unique green algae that thrive as endophytic parasites in the leaves of various members of the Araceae. The DNA sequences of the parasitic populations were originally acquired from infected leaves of subtropical Arisarum vulgare. However, several previous studies showed that the members of the Phyllosiphon clade also occur as free-living algae on...

Purpose The current pilot study explored food insecurity, waste, related behaviours and cooking confidence of UK consumers following the COVID-19 lockdown. Design/methodology/approach Data were collected from 473 UK-based (63% female) in March 2020. A cross-sectional online survey measured variables including insecurity prevalence, self-reported management behaviours, frequency use a range meth...

Larvicidal effect of Azadirachta indica on mosquitoes has been studied in the present work. The water extracts of air dried leaves and fresh leaves separately have been used for the study. Different concentrations were made of all these extracts and twenty second instar larvae of Culex pipiens fatigans were placed in each concentration separately. Control was set up for each experiment. Mortali...

Corn residues (cobs, leaves and stalks) are abundantly available renewable materials that can be used as an energy source in gasification and combustion systems. Proper understanding of the physical properties of these materials is necessary for their use in thermochemical conversion processes. The physical properties (moisture content, particle size, bulk density and porosity) of corn cobs, le...

Plants of Coffea dewevrei De Wild. et Th. Durant var. excelsa Chev. growing in nursery beds in a lath house at the Instituto Agronomico, Campinas, Brazil, exhibit frequently a type of chlorosis in the leaves (1). Repeated attempts were made to improve the condition of the chlorotic plants by spraying their leaves with salt solutions of various elements, including iron, zinc, manganese, magnesiu...

BACKGROUND Xeric forests dominated by two tree species, Scutia buxifolia (Rhamnaceae) and Celtis tala (Ulmacea), are temperate, semi-deciduous wooded communities that represent the most abundant woodlands on the eastern plains of Buenos Aires Province, Argentina. The district of Magdalena has one of the most well-preserved native-forest areas, with an environmental heterogeneity that gives rise...

The present study examines the separate and synergistic effects of macroalgal extract static magnetic field (SMF) on germination soybean seeds (Glycine max (L.) Merrill), cv. Abelina, seedling growth, chlorophyll, carotenoids content in leaves. Algal was produced from freshwater green macroalga (Cladophora glomerata) using ultrasound-assisted extraction. tests were conducted two stages. Firstly...
