Abstract Lisianthus (Eustoma grandiflorum) is an ornamental species used as a potted plant or cut flower, its popularity due to the diversity of colors, number flower buds, and shelf life. Nevertheless, during first phases development, problems such foliar chlorosis root diseases affects most cultivars, causing poor growth, thin stems, few flowers. The use growth-promoting rhizobacteria (PGPR) ...

introduction in recent years, rainfall deficiency was an increasing problem in most countries; which limited the production of agricultural crops. among abiotic stresses the plants encountered, drought stress is considered as the most important limiting factor in plants growth and reproduction in natural and agricultural systems through most parts of the world; while drought stress causes 45% i...

this study in order to evaluate the possibility of improving the root growth of lentil with use mycorrhiza symbiosis with cooperation azospirillum bacteria under rainfed conditions was conducted. a tri-factorial experiment was organized on the basis of randomized complete block design with four replicates, in which factor m was the mycorrhizal inoculums in three levels including (not use, use m...

the effects of arbuscular mycorrhizae on water use efficiency and some growth characteristics of maize were studied at three water regimes. an farm experiment was carried out using a split plot based randomized complete block design with 3 replications. main plot was under water deficit condition (100%fc, 66%fc, 33%fc) and sub plot included application of two species of mycorrhizae, m1:glomus m...

Salinization has led to the deterioration of ecological environment, affected growth plants, and hindered development agriculture forestry. Arbuscular mycorrhizal (AM) fungi, as important soil microorganisms, play significant physiological roles in promoting plant nutrient absorption improving structure. Puccinellia tenuiflora (Turcz.) Scribn. et Merr. Songnen saline-alkaline grassland was sele...
