Salt stress severely reduces growth and yield of plants. Considering the positive effects selenium (Se) chitosan (Cs) separately against abiotic stress, in these experiments, we synthesized chitosan–selenium nanoparticles (Cs–Se NPs) investigated their ability to reduce negative salt on some biochemical parameters bitter melon (Momordica charantia). Bitter plants were grown at three NaCl salinity levels (0, 50, 100 mM) a foliar spray Cs–Se NPs 10, 20 mg L−1) was applied. Some key...

T) were evaluated against five soil borne phytopathogenic fungi (Fusarium graminearum, Rhizoctonia solani (AG4 AG5), Macrophomina phaseoli Phytophtora cacturum) dual culture techniques through production volatile non-volatile inhibitors, pH temperature effects on mycelial growth also evaluated. All had a marked...

An efficient method to instantly assess drought-tolerant plants after germination is using osmoregulation in tissue culture media. In this study, the responses of three Iranian melon genotypes sorbitol (0.1, 0.2, and 0.4 M) or polyethylene glycol (PEG) (0.009, 0.012, 0.015 were evaluated as drought stress simulators MS medium. 'Girke' (GIR), 'Ghobadloo' (GHO), 'Toghermezi' (TOG) genotypes. GIR reputed a genotype Iran. The PEG decreased coleoptile length, fresh weight, photosynthetic pigments...

This experiment aims to evaluate the effects of vermicompost produced from sheep manure on growth, yield and quality 2 fruit cucumber (Cucumis sativus L.) varieties (cv. ‘Sultan F1’ cv. ‘Storm F1’) under greenhouse condition. Four treatments at rate 0 (control), 10, 20 30 t ha-1 were incorporated into top 15 cm soil. During experiment, fruits harvested three times per week number weight recorded for 3 months. Leaf number, plant height chlorophyll content measured 30, 60 90 days after...

Potatoes are a staple food with high antioxidant properties that can positively affect population health. The beneficial effects of potatoes have been attributed to tuber quality. However, the quality related researches at genetic levels very few. Sexual hybridization is powerful strategy for producing new and valuable genotypes In this study, 42 breeding potato in Iran were selected based on appearance characteristics such as shape, size, color, eyes tubers, yield marketability. tubers...

Abstract The need to discover new strategy enhance agricultural productivity while minimizing negative effects on cultivation system is the driving force behind much novel research. Little known about use of natural growth promoters, in combination with Spirulina algae extract ( Sae ), plants' quality and quantity characteristics. This can be an effective reduce impact environmental stress plants. aim this study was investigate promoters functional properties enzymatic activity Cape...

In this study, in vitro organogenesis of Gladiolus grandiflorus cultivar pink corm segments were evaluated by culturing calli modified MS medium supplemented with 3% sucrose and 0.7% agar different concentration BAP (0, 1, 2 4 mg L(-1) medium) NAA 0.5, 1 factorial experiment Completely Randomized Design (CRD). order to obtain calli, (Aprox. 5 x mm size) kept (Murashige Skoog, 1962) that was 2, 4-D, agar. The results showed increasing the from 0 simulated plantlet regeneration but no...

Screening and identification of tolerant genotypes using osmotic materials under in vitro culture could be rapid, easy, even accurate. In this research, three Iranian landraces Cucurbita sp. included Tanbal Ajili (Cucurbita maxima Duch.), Razan pepo L.), Balghabakhi moschata Duch.) seeds were cultured ¼ MS medium. After germination, plantlets transferred to media containing mannitol PEG 6000. Mannitol at concentrations 0.1, 0.2, 0.4 M 0.009, 0.012, 0.015 M, respectively, added into the...

The D2/D3&nbsp;LSU rDNA expansion segment of 13 isolates attaching tea shrubs roots in gardens that verified by morphological and morphometrical studies as&nbsp;Pratylenchus loosi&nbsp;Loof, 1960 from Guilan province, North Iran, were amplified sequenced. Amplification the segments yielded one fragment at over all sequenced as 787 bp size. DNA sequences aligned using Clustral X1.81 together with three similar region of&nbsp;P. loosi&nbsp;isolates available Genbank database (Isolate T...

Abstract Background Potato virus Y (PVY) is among the economically most damaging viral pathogen in production of potato ( Solanum tuberosum ) worldwide. The gene Ry sto derived from wild relative stoloniferum confers extreme resistance to PVY. Results presence and diversity were investigated relatives (298 genotypes representing 29 accessions 26 tuber-bearing species) using PacBio amplicon sequencing. A total 55 unique Rysto-like sequences identified 72 12 10 species six resistant controls...

Belowground interactions between plant roots, arbuscular mycorrhizal fungi (AMFs), and growth-promoting rhizobacteria (PGPR) can improve growth yield under abiotic stress conditions. A pot factorial experiment based on completely randomized design with three replications was conducted to investigate the effects of AMFs (without inoculation as control, Funneliformis mosseae intraradices) PGPRs control Pseudomonas fluorescens p-169 inoculation) roselle (Hibiscus sabdariffa L.) grown water...

Physalis angulata L. berries are green in the initial stage of maturity and turn yellow when fully mature due to an increase carotenoids. However, coloration epidermis berry should not be reference for harvesting maturity, since calyx is closed. The use edible chitosan coating delays color changes by reducing respiration rate. This work studies effect harvest on shelf life coloring Three factors were considered, being (green (GM), yellowish-green (YG) (Y)), (0, 0.5, 1%), storage time (10,...

Rosa damascena as a holy ancient plant with modern uses in perfumery and therapeutic processes, should be more investigated due to its utilization food ingredients, preclinical clinical studies, cosmetics industry. Here, we have evaluated the proline content, total phenol of sepal petal, oil essential (EO) composition different damask rose ecotypes [(Oroumieh; OR), (Golab; GB), (Oskou; OS), (London; LN), (Mahallat; MT)]. The highest content produced GB ecotype. There was positive correlation...
