A Miocene succession exposed at the Cabo Ledo and Miradouro da Lua sections in Onshore Kwanza Basin, Angola, was examined for palynology. Palynomorphs of preliminary late age identified are presented herein. The upper part Quifangondo Formation is dated as middle Tortonian based on co-occurrence pollen grain Fenestrites spinosus dinoflagellate species Selenopemphix armageddonensis. palynomorph ...

OBJECTIVES The present study was aimed to investigate the α-amylase inhibition and antioxidant activities of methanolic extract of Amaranthus caudatus Linn (MeAc). METHODS Methanolic extract of Amaranthus caudatus was screened for α-amylase inhibition activity by CNPG3 method (2-chloro-p-nitrophenyl-α-D-maltotrioside) and antioxidant activity was evaluated by 1,1-diphenyl-2-picryl-hydrazile (...

carbon dioxide is the most important resource for crop growth. in order to investigate the effect of elevated co2 concentration on morphological and physiological characteristics of sesame (sesamum indicum l.) and amaranthus (amaranthus retroflexus l.) an experiment was conducted in greenhouse conditions. the experiment was factorial based on randomized complete block design with six treatments...

Two new species, Zercon (Zercorientalia) formosianus sp. nov. and Zercon (Zercorientalia) spinosus sp. nov., are described from the high mountain zone of Taiwan. A new subgenus, Zercon (Zercorientalia) subgen. nov., is established for these species, on the basis of a unique combination of podonotal chaetotaxy and pore positions. Zercon (Zercorientalia) sinensis Petrova & Taskaeva, 1968 is trans...

Five new species of Hypseloecus viz., Hypseloecus acutus sp. nov., Hypseloecus articulatus sp. nov., Hypseloecus belli sp. nov., Hypseloecus orientale sp. nov. and Hypseloecus spinosus sp. nov. are described from India. The genus is recorded for the first time from India collected on hemiparasitic plants of the genera Dendrophthoe and Viscum (Santalales). A key to identification of the five spe...

Dark germination of Amaranthus retroflexus L. seeds at 35 degrees increased after several days of prechilling at 20 degrees or lower. Irradiation with far-red light for short periods during the early hours of a prechilling period at 10 degrees inhibited subsequent dark germination at 35 degrees . The inhibition was completely reversible with red light. Far-red irradiation in the latter part of ...

Red Amaranth (Amaranthus tricolor) and green Amaranth (Amaranthus viridis) are two very important leafy vegetables consumed in most parts of India, not only for their flavours, but also for their pharmacological activities. The cooking processes are different in the different part of this country, and therefore, the present study was designed to analyze their in vitro antioxidant profile before...

This study aims to determine the allelopathic potential of Amaranthus retroflexus (Ar) with different climatic zones on seed germination and growth of A. tricolor (At) treated with a gradient N addition. Ar leaf extracts only displayed significantly allelopathic potential on the underground growth of Ar but not the aboveground growth of At. The allelopathic potential of Ar leaf extracts on root...

On a farm in Slovenia two cows died overnight without any previous signs of disease. The cows were fed green forage, containing a big portion of redroot pigweed (Amaranthus retroflexus) at least for four consecutive days. Poisoning with this plant was suspected. Pathomorphological changes established by the necropsy of both cows confirmed the suspi-

In grain amaranthus (Amaranthus hypochondriacus L.) ten genotypes were evaluated for twelve characters under four plant density levels viz. very high (D ), high (D ), normal (D ) and low plant density (D ) 1 2 3 4 levels to study the influence of different plant density levels on growth and grain yield of grain amaranthus. The study was conducted at College Orchard, Department of Horticulture, ...
