A hydroponic culture experiment was conducted to study the effect of copper toxicity on root morphology, ultrastructure, and copper accumulation in Moso bamboo (Phyllostachys pubescens). Root ultrastructure of Moso bamboo was studied by transmission electron microscopy and scanning electron microscopy. Application of 200 μM Cu resulted in an accumulation of 810 mg kg(-1) dry weight and 91 mg kg...

the use of recent technologies for the increase of growth indexes and the plants yields is an important aspects and till now many research works for this has been done. one of these efforts is the usage of magnetic water and zeolite for the increase of yield plants. this research work is an study on the effects of magnetic water and zeolite that has been done on frame work of pore random design...

The bud chip nursery technique is a with one which commonly used in sugarcane. purpose of this study was to determine the effect concentration fermented cow urine on growth single sugarcane (Saccharum officinarum L.) cuttings. This randomized block design experiment (RAK) 5 replications and treatment levels, namely: P0 = without giving concentration; P1 Concentration 25% urine; P2 20% P3= 75%; ...

     As an herbaceous, perennial, and evergreen plant, Vetiver Grass (Chrysopogon zizanioides L.) can be used for the improvement and development of arid and semi-arid rangelands. To assess the interaction effect of organic and biological fertilizers on the growth and physiological traits of Vetiver grass, the dry weight of shoots and roots, essential oils, chlorophyll, carotenoids, and proline...

Salt tolerance of new wheat cultivar Banysoif 1 was investigated to find relevant culturing strategy in saline areas. Wheat cv. Banysoif 1 was grown in clay soil for 7 days in different pots. Then seedlings were irrigated by different saline waters (0, 60, 120, 180, 240 and 320 mM NaCl) near the field capacity. Plants were kept in the natural condition under these saline levels for 155 days. Fr...

agrobacterium rhizogenes (pri), a causative agent of hairy root disease, effectively induces hairy root formation in a variety of plant species. in our study four bacterial strains ar15834, a4, 9435 and c318 and three explants types leaf, stems and roots, were examined. hairy roots were induced from roots, stems and leaf explants. the highest transformation efficiency of 77% was achieved by usi...

ethylene as a plant hormone plays various functions in a variety of physiological phenomena including seed germination, root initiation on stem cutting, senescence and organs abscission. in our previous investigation, five rose genotypes were identified showing high-sensitivity or low-sensitivity to exogenous ethylene treatment. the purpose of this study was to evaluate the rooting capacity and...

Melissa officinalis is a plant of Lamiaceae family with medicinal properties which is important for its aromatic, synthetic, and secondary metabolites. The aim of this research was to study the effect of selenium on secondary metabolites and antioxidant properties of Melissa officinalis. For this purpose, an experiment was done in a completely randomized design with four repli...

The aim of the present study was to examine whether increasing molybdenum (Mo) concentration affects the growth and Mo concentration of maize (Zea mays L. cv Norma SC) and sunflower (Helianthus annuus L. cv Arena PR) seedlings within laboratory conditions. In this experiment, calcareous chernozem soil was used and Mo was supplemented into the soil as ammonium molybdate [(NH4)6Mo7O24.4H2O] in fo...
