Volatile components of three parts of Pimpinella tragium Vill. (Umbelliferae family) from Iran were investigated qualitatively and quantitatively for the first time. Essential oils were isolated by hydro-distillation from stems plus leaves, inflorescence and seeds of P. tragium individually. The plant materials were collected from Polour (Northeast of Tehran Province). The yields of the ...

Salinity is one of the main challenges in agriculture, especially arid and semi-arid regions. Salicylic acid application may be a strategy to mitigate harmful effects salt stress on plant growth. Basil (Ocimum basilicum ) medicinal, spice, ornamental grown around world that has its growth reduced by stress. Therefore, objective was evaluate salicylic mitigating damage caused ‘Cinnamon’ basil. G...

Inflorescence development in cereals, including such important crops as rice, maize, and wheat, directly affects grain number and size and is a key determinant of yield. Cytokinin regulates meristem size and activity and, as a result, has profound effects on inflorescence development and architecture. To clarify the role of cytokinin action in inflorescence development, we used the NanoString n...

We constructed an equalized cDNA library from Arabidopsis inflorescence shoot apices including inflorescence meristem, floral meristem and flower tissue collected before stage 5 of flower development. The cDNA clones were arrayed on membranes and were differentially screened using cDNA pools from vegetative and inflorescence tissues as probes. Each clone was classified by expression specificity...

Sexual dimorphism may be especially pronounced in wind-pollinated species because they lack the constraints of biotically pollinated species that must present their pollen and stigmas in similar positions to ensure pollen transfer. Lacking these constraints, the sexes of wind-pollinated species may diverge in response to the different demands of pollen dispersal and receipt, depending on the ma...

The INTERFASCICULAR FIBERLESS/REVOLUTA (IFL1/REV) gene is essential for the normal differentiation of interfascicular fibers and secondary xylem in the inflorescence stems of Arabidopsis. It has been proposed that IFL1/REV influences auxin polar flow or the transduction of auxin signal, which is required for fiber and vascular differentiation. Assay of auxin polar transport showed that the ifl1...

Knowledge of plant nutritional status allows an understanding of the physiological responses of plants to crop fertilization. A hydroponic experiment evaluated the symptoms of macronutrient deficiency in cauliflower 'Verona' and determined: a) the macronutrient contents of foliar tissues when visual symptoms were observed, b) macronutrients content of foliar and inflorescence tissues at harvest...

to evaluate the effect of shoot girdling, fruit thinning, urea, sucrose and zinc on inflorescence bud retention in pistachio, an experiment comprised of 12 treatments including girdling, fruit thinning, application of urea (0.5%), and sucrose (3 and 5%) and their combination of the first two with urea plus zinc sulfate (0.05 and 0.1% of pure zinc) as well as a combination of the two with urea, ...

ABSTRACT Some vegetables have been used as an innovation in the ornamental plant market, such cauliflower, which has well-defined morphological traits. This study aimed to evaluate effect of paclobutrazol, applied via soil, order produce cauliflower for purposes. The design was completely randomized with five treatments and seven replicates. consisted doses growth regulator paclobutrazol (PBZ) ...

Vitis vinifera glycosyl hydrolase family 17 (VvGHF17) is a grape apoplasmic β-1,3-glucanase, which belongs to glycosyl hydrolase family 17 in grapevines. β-1,3-glucanase is not only involved in plant defense response but also has various physiological functions in plants. Although VvGHF17 expression is negatively related to the length of inflorescence in grapevines, the physiological functions ...
