This study was carried out to evaluate the effects of salicylic acid in Marfona potato cultivar (Solanum tuberosum L.) for reducing the pathogenesis of Rizoctonia solani in potato tubers under greenhouse conditions. The pots sterilized soils had been infected by R. solani (21B1 strain) two weeks before transplanting the potato plantlets. The seedlings were treated with 0 (control), 0.1, 0.2, 0....

In order to study effect of salicylic acid and calcium foliar application on growth, yield and yield components of strawberry plants as a factorial in completely randomized experimental design with four replications. This factors included of salicylic acid in 3 levels (0.25, 0.5 and 0.75 mM) and calcium in 2 levels (2.5 and 5 mM) spray on strawberry. Results showed that salicylic acid (0.25 mM)...

Effect of salicylic acid combined with glutamin on rose (Rosa Baccara) cut flowers was studied. The study was conducted in a factorial arrangement, carried out in a complete randomized design. The factors were Salicylic acid (0,1, 2 and 4 mM) and glutamin (0, 1.5 and 3 mM).The effects of treatments on the total chlorophyll content, ACC-Oxidase activity, anthocyanin leakage, membrane stability a...

The components of the proton motive force (Deltap), namely, membrane potential (Deltapsi) and transmembrane pH gradient (DeltapH), were determined in the nitrifying bacteria Nitrosomonas europaea and Nitrobacter agilis. In these bacteria both Deltapsi and DeltapH were dependent on external pH. Thus at pH 8.0, Nitrosomonas europaea and Nitrobacter agilis had Deltapsi values of 173 mV and 125 mV ...

The phenolic composition of extracts from Uncaria tomentosa L. from different regions of Costa Rica was studied using advanced analytical techniques such as UPLC/TQ-ESI-MS and (13)C-NMR. Samples from leaves, stems, bark and wood (n = 22) were subjected to extraction to obtain phenolic and alkaloid extracts, separately. Comparatively, higher values of total phenolic content were observed for lea...

This study appraises the antioxidant and antimicrobial attributes of various solvent extracts (absolute methanol, aqueous methanol, absolute ethanol, aqueous ethanol, absolute acetone, aqueous acetone, and deionized water) from bark, leaves and seeds of Pongamia pinnata (L.) Pierre. Maximum extraction yield of antioxidant components from bark (16.31%), leaves (11.42%) and seeds (21.51%) of P. p...

UNLABELLED Data emerging from the past 10 years have consolidated the rationale for investigating the use of aspirin as a chemopreventive agent; however, the mechanisms leading to its anticancer effects are still being elucidated. We hypothesized that aspirin's chemopreventive actions may involve cell-cycle regulation through modulation of the levels or activity of cyclin A2/cyclin-dependent ki...

The hepatic distribution kinetics of salicylic acid was determined using a single-pass dual hepatic artery (HA) and portal vein (PV) perfused in situ rat liver preparation. Bolus doses of [14C]salicylic acid and of reference markers ([3H]-water and [14C]-sucrose) were injected in a random order into either the HA or PV and then, after an appropriate interval, into the alternate vessel. The hepa...
