To investigate the effects of nutrient-solution concentrations of potassium (K) and calcium (Ca), as well as different ratios of K/Ca, on growth and flowering of lisianthus (Eustoma grandiflorum) under soilless culture conditions, a factorial experiment was conducted with two factors including two K levels (300 and 400 mg/L) and three Ca levels (80, 100 and 160 mg/L). Results showed that K= 400...
An experiment was conducted to investigate the effects of K/Ca ratios of nutrient solution on physiological traits, cut flower vase life and postharvest changes of rose. The main experiment was factorial based on completely randomized design with two cvs. of rose (Magic Red and Capitol), five K/Ca ratios in the nutrient solution (4:4, 6:4, 6:3, 8:3, 10:2) and three replications. Increasing the ...
افزایش روزافزون جمعیت از یک سو و محدودیت اراضی به دلیل توسعه شهرنشینی از سوی دیگر، موجب گردیده که اقتصادی کردن واحدهای تولیدی در اولویت اول سیاست گذاران و مسئولان کشور قرار گیرد. یکی از راه کارهای عملی اقتصادی کردن واحدهای تولیدی ایجاد و تنوع کشت و معرفی گونه های جدید صادراتی و درآمدزا هست. فیسالیس یکی از محصولاتی است که به واسطه امکان تولید بالای آن در گلخانه و قابلیت فراوری آن در صنایع تبدیلی...

effects of different k/ca ratios on the growth, yield and physiological characteristics in galia (cucumis melo var. reticulatus l. naud. cv. galia) grown in hydroponics were evaluated. the experiment was arranged in a completely randomized design of three replicates. melon seeds were sown in a medium containing perlite and vermiculite (3:1 v:v) and then irrigated with water containing different...
Intranasal route, ensuring suitable bioavailability of medicines under circumvention of the gastrointestinal degradation and hepatic first-pass elimination, has been a popular choice for drug delivery. Among nasal dosage forms, mucoadhesive solid inserts have been shown to resist mucociliary clearance and provide a prolonged nasal residence time. Hence, the purpose of this study was the prepara...

this experiment was conducted to evaluate the effects of salt stress on some agro-physiological traits in ten varieties of bread (triticum aestivum l.) and durum (triticum turgidum l.) wheats in seedling stage. a greenhouse experiment was carried out as a split plot experiment based on a completely randomized design with four replications in hydroponic condition. different agronomic and physiol...
One of the problems for unequal distribution of salts in the root media is toxicity of sodium (Na) and reduced uptake of some nutrients, particularly calcium (Ca) and potassium (K), by the roots growing in the saline section. There is a hypothesis that addition of Ca and K to these systems might alleviate salt-induced damages to plants. This study was carried out to evaluate the effect of Ca an...
in a greenhouse experiment, the effects of waterlogging, sewage sludge and manure on the uptake and concentrations of p, k, ca, mg and na in root and shoot of sunflower (helianthus annuus l.) were investigated. a factorial experiment based on completely randomized design with three replications including duration of waterlogging at five levels (0, 2, 4, 8, 22 days), source of organic fertilizer...
