Evaluating Foliar Application of Calcium Nitrate, Calcium Chloride and Boric Acid on Physiological Disorders of ‘Kaleh - Ghoochi’ Pistachio
Pistachio suffers from some physiological disorders such as fruit abscission, endocarp lesion, blankness, non-split, early-split and deformed nuts. In this experiment, the effects of calcium nitrate (2 gr/lit), calcium chloride (2 gr/lit), boric acid (200 ppm) and their combination treatments were investigated on physiological disorders of ‘Kaleh-Ghoochi’ pistachio. Foliar application was appli...
متن کاملComparison of Boric Acid with Clotrimazole in the Treatment of Recurrent or Resistant Vulvovaginitis Caused by Non-Albicans Species of Candida
Background: Vulvovaginal candidiasis is one of the most common infections in gynecologic filed, and non–albicans Candida species are emerging causative microorganisms. This species shows resistance to routine treatments. One of the suggested treatments is administration of vaginal suppositories of boric acid. The aim of the present study was to compare boric acid with clotrimazole in the treatm...
متن کاملBoric acid reversibly inhibits the second step of pre-mRNA splicing.
Several approaches have been used to identify the factors involved in mRNA splicing. None of them, however, comprises a straightforward reversible method for inhibiting the second step of splicing using an external reagent other than a chelator. This investigation demonstrates that the addition of boric acid to an in vitro pre-mRNA splicing reaction causes a dose-dependent reversible inhibition...
متن کاملMICROBIOLOGICAL EVALUATION OF SOME OPHTHALMIC PREPARATIONS CONTAINING DIFFERENT CONCENTRATIONS OF BENZALKONIUM CHLORIDE
Zinc sulphate and boric acid ophthalmic preparations, containing benzalkonium chloride as preservative, have been investigated against gram-negative and positive bacteria. Viability of bacteria was found after 7 days, although it was completely suppressed after 24 hours of inoculation. Zinc sulphate generally increases the antimicrobial activity of benzalkonium chloride, whereas boric acid ...

The objective of the present study is to investigate the impact of spraying boric acid on vegetative and reproductive growth of ‘Camarosa’ strawberry (Fragaria × ananassa Duch.). The strawberry plants were sprayed with Boric acid at 0 (control), 50 and 100 mg L-1 at 30 days after planting. In general, results indicated that spraying plants with boric acid had a significant effect on yield, frui...
