The effect of different media including the growth regulators on somatic embryogenesis from Mexican lime was studied. The average embryo formation after 60 days from unfertilized ovules in different media was evaluated at 0 to 33.75%. The most effective hormone to stimulate embryogenesis was GA3 at 0.01 and 0.1 mg/l concentrations. Malt extract (ME) at 300 mg/l increased embryo formation, where...

Extended Abstract Introduction and Objective: Due to the very high diversity among the genotypes of quinoa (Chenopodium quinoa), it has shown a very high adaptability and stability in different climates. Therefore, this experiment was performed to investigate the morphological and genetic diversity of 14 quinoa genotypes and compare them with the control genotype of the region (Titicaca). Ma...

In order to improve the quantitative and qualitative traits of lisianthus (Eustoma grandiflorum “Mariachi Blue”) a factorial experiment ws performed as completely randomized design at three levels of vermicompost (0, 5 and 10% v/v) and humic acid (0, 2 and 4 kg/m3) with three replications, under the greenhouse conditions. Evaluated traits were number of Leaves, buds and branches, pe...

This experiment was performed to investigate the effect of some Trichoderma spp. isolates as growth promoters of cucumber (Cucumis sativus L.) seedlings under greenhouse conditions. Inoculai of 19 Thrichoderma spp. isolates were prepared from disinfected wheat grain. The upper half of the soil in pots (containing field soil and sand) was mixed with these inoculai at 3% ratio and the pots were i...

In order to investigate the effect of form of nitrogen (N) [ammonium (NH4) and nitrate (NO3)] and calcium (Ca) levels of nutrition solution on quantitative and qualitative yield of cut rose flower (Rosa hybrida L.), cv. Vendentta, in soilless culture condition, an experiment was conducted in greenhouse of the National Ornamental Plants Research Station of Mahallat. The experiment was factorial,...

In order to evaluate the effect of different training systems on growth, yield and fruit quality of greenhouse cucumber (Cucumis sativus cv. Gohar) this experiment was set out in a randomized complete block design with three replications. Treatments consisted of four training systems including twin-stem system (V-shape), modified twin-system, high-wire system and horizontal system (single-stem)...

  Seed priming is the most important technique for increasing the germination power. This study was conducted to investigate the effects of halopriming and hydropriming on improvement of seed germination in black locust (Robinia pseudoacacia L.) in a completely randomized design with 4 replications. Halopriming treatments of KNO3 with concentrations including (100, 250, 500, 750 mM) and hydropr...
