Oxidative stress leads to formation of free radicals, reactive oxygen species and nitrogen species, which leads to numerous pathophysiological disorders. The present study is aimed to evaluate the free radical scavenging potential of flowers of Gomphrena globosa. The extracts from the flowers of Gomphrena globosa were prepared in solvents viz. methanol, ethanol and butanol. Spectrophotmetric an...

A decline in growth, flowering, and boll (fruit) retention is referred to as cutout in cotton (Gossypium hirsutum L.). Fruit load affects cutout, possibly through hormonal effects. Experiments were conducted to test the hypothesis that fruits are a source of abscisic acid (ABA) that moves into fruiting branches and growing points where it inhibits growth, flowering, and boll retention. Removal ...

Phytoremediation offers an ecologically and economically attractive remediation technique for soils contaminated with polycyclic aromatic hydrocarbons (PAHs). In addition to the choice of plant species, agronomic practices may affect the efficiency of PAH phytoremediation. Inorganic nutrient amendments may stimulate plant and microbial growth, and clipping aboveground biomass might stimulate ro...

This study presents breeding and pollination systems of Aristolochia maxima and A. inflata in a seasonal tropical forest of Panama. Aristolochia is the most diverse genus of Aristolochiaceae, with ∼120 species distributed throughout the tropics and subtropics. All the Aristolochia species studied so far are pollinated by saprophagous flies of different families, which are presumably deceived by...

The perennial and evergreen twining vine, Lonicera japonica is an important herbal medicine with great economic value. However, gene expression information for flowers and leaves of L. japonica remains elusive, which greatly impedes functional genomics research on this species. In this study, transcriptome profiles from leaves and flowers of L. japonica were examined using next-generation seque...

Colletotrichum acutatum infects citrus petals and induces premature fruit drop and the formation of persistent calyces. The accumulation of hormones and other growth regulators, and differential gene expression in affected flowers and young fruit, was examined following fungal infection. Ethylene evolution increased threefold and indole-3-acetic acid (IAA) accumulation was as much as 140 times....

Research goal: Based on the information found in literature biochar, its ability to improve quality and yield of productions influence soil microflora. In this work, studies were carried out at different concentrations pots assess whether addition material growing medium can growth control biotic abiotic stresses Astrophytum myriostigma capricorne. Materials Methods: The experiments, started Ju...

Quantitative real-time reverse transcription-polymerase chain reaction (qRT-PCR) is the most commonly used and powerful method for gene expression analysis due to its high sensitivity, specificity, and high throughput, and the accuracy of this approach depends on the stability of reference genes used for normalization. Taihangia rupestris Yu and Li (Rosaceae), an andromonoecious plant, produces...

Two experiments were carried out to evaluate the effects of organic fertilization as an alternative chemical on yield and quality cherry tomato grown under different irrigation depths in protected environment, 2013 2014. The experimental design was randomized blocks (5 x 3 factor), with five factors (70%, 85%, 100%, 115% 130% ETc) three types fertilization: no fertilized soil (control), NPK (Ch...

The orchid Ophrys sphegodes Miller is pollinated by sexually excited males of the solitary bee Andrena nigroaenea, which are lured to the flowers by visual cues and volatile semiochemicals. In O. sphegodes, visits by pollinators are rare. Because of this low frequency of pollination, one would expect the evolution of strategies that increase the chance that males will visit more than one flower...
