ABSTRACT As part of an ongoing project treating the ferns and lycophytes from region Viçosa, Minas Gerais State, Brazil, we here present taxonomic treatment early divergent lineages leptosporangiate ferns: families Dennstaedtiaceae, Lindsaeaceae Saccolomataceae. We have been sampling remnant forest patches since 2012; also fully reviewed collection herbarium VIC other online collections: F, IAN...

LTHOUGH self-compatible (SC) species frequently can hybridize as females A with related self-incompatible (SI) species, the reciprocal cross is often impeded by inhibition of pollen tube growth in the style. This unilateral incompatibility can also be demonstrated between species of widely separated genera, or even of different families, which suggests that it is of fundamental significance in ...

The mechanism of chilling resistance was investigated in 4-week-old plants of the chilling-sensitive cultivated tomato, Lycopersicon esculentum Mill. cv H722, and rooted cuttings of its chilling-resistant wild relative, L. hirsutum Humb. and Bonpl., which were chilled for 3 days at 2 degrees C with a 14-hour photoperiod and light intensity of 250 micromoles per square meter per second. This chi...

Tomato (Lycopersicon esculentum Mill.) polyphenol oxidases (PPOs) are encoded by a seven-member gene family that exhibits complex patterns of differential expression during growth and differentiation. Antisense down-regulation of constitutive and induced PPO expression results in hypersusceptibility to pathogens, suggesting a critical role for PPO-mediated phenolic oxidation in plant defense. H...

The fermentation product of herbs by lactic acid bacteria (FHL) was assayed for antifungal activities against Rosellinia necatrix, Helicobasidium mompa, Fusarium oxysporum, Pythium graminicola and Pyricularia oryzae. FHL completely inhibited the growth of R. necatrix, H. mompa, P. graminicola and P. oryzae, and reduced the growth of F. oxysporum by 35%. When the seeds of Medicago sativa L. (alf...

in order to evaluate the effects of crop cultivars and living mulchon sunflower yield and weed control, a field experiment was carried out as factorial arrangement based on a randomized complete block design with three replications in 2013. treatements were sunflower cultivars (‘azargol’, ‘allstar’, ‘farokh’) and weed control treatments (weed-free, weed-infestation and intercropping of fagopyru...

Fagopyrum esculentum commonly named as buckwheat plant is pseudocereal food crops and healthy herbs but is not known as a bioindicator of environmental condition. In the present study, the effects of ZnO nanoparticles (NPs) and microparticles (MPs) on plant growth, bioaccumulation, and antioxidative enzyme activity in buckwheat were estimated under hydroponic culture. The significant biomass re...

In vitro toxicological influence of culture filtrates of Fusarium oxysporum f. sp. lycopersici (Sacc.) Snyder & Hans was investigated on seed germination, seedling growth and physiology of tomato (Lycopersicum esculentum Mill.) under chromium(VI) stress. Original culture filtrates of the fungus and three concentrations of Cr(VI) viz. 50, 75 and 100 mg L1 were used in laboratory bioassays either...

this study sought to investigate the effects of two tomato varieties [Lycopersicon esculentum Mill. var. esculentum (Esc) and Lycopersicon esculentum Mill. var. cerasiforme (cEr)] on acetylcholinesterase (AchE) and butyrylcholinesterase (bchE) activities in vitro. Phenolics content, carotenoids characterisation, inhibition of Fe2+ and quinolinic acid-induced malondialdehyde (MDA) production in ...

conclusions decreases of tc, ldl and tg may be related to tomato antioxidant effect. this course in human required more investigations. results results showed that in chol group, all lipids increased significantly (p < 0.05) except hdl compared to the control group. tomato and tomato paste supplementation decreased tc, ldl and tg concentration significantly (p < 0.05) compared to chol group. to...
