Most of the research on Phragmites australis is restricted to sites on the European continent even though P. australis occurs abundantly in many regions in the Asian and other continents under different climatic and habitat conditions. The populations used in this study were collected from different parts of Iran. All these populations were grown in the same conditions in experimental field, lo...

to evaluate symbiotic effectiveness and salt tolerance of sinorhizobium meliloti strains, 50 rhizobial strains were isolated from root nodules of medicago sativa cultivated in tehran and zanjan fields. under n-free conditions, the symbiotic effectiveness of different sinorhizobium meliloti strains of bami cultivar were evaluated under greenhouse conditions using 50 sinorhizobium meliloti strain...

Gladiolus is commonly propagated from corms. The multiplication rate of corms low and to increase the propagation rate, we examined a combination apical bud removal application growth regulators. experiments were conducted in two varieties, ‘Rose Supreme’ ‘White Prosperity’, over seasons. buds on planting either removed or left intact before same soaked suspension with 100 ppm benzyladenine (BA...

Zinnia elegans, an annual flowering plant of the genus Zinnia, is one of the best known zinnias. Present study was conducted to evaluate the effect of different growing media on the growth and flowering of Zinnia elegans. Seven different growth media including coconut compost, silt, soil loam, leaf manure, (leaf manure + silt; 2:1), (coconut compost + soil loam; 1:1) and (leaf...

Potato (Solanum tuberosum L.) plantlet regeneration potentiality was studied in ammonium nitrate (NH4NO3) free tissue culture medium. Four different treatments were designed from the compositions of stock solution-01 plant Those -Treatment-1 (Stock solution -01 as recommended by Murashige & Skoog (1962), Treatment-2 (MS without having NH4NO3), Treatment-3 solution-01without NH4NO3 but other...

Grafting in species other than Arabidopsis has generated persuasive evidence for long-distance signals involved in many plant processes, including regulation of flowering time and shoot branching. Hitherto, such approaches in Arabidopsis have been hampered by the lack of suitable grafting techniques. Here, a range of micrografting methods for young Arabidopsis seedlings are described. The simpl...

The study aimed to investigate the effects of mycorrhizal inoculation on growth and development; three plant species: Petunia hybrida, Antirrhinum majus, Dianthus chinensis. as well heavy metals in soil. measured various parameters such shoot fresh weight, root flower numbers, length, diameter, leaves number, petiole length. Results showed a significant increase weight 10.74 g, weight1.77g, num...

ABSTRACT Substrate composition is a major factor influencing seedling quality. This study aimed to evaluate the potential of biosolid as substrate component in initial growth Syagrus romanzoffiana (Cham.) Glassman seedlings. The experimental design was completely randomized, with six treatments, five replicates and seven plants per plot. treatments consisted substrates resulting from mixture su...
