in order to study impacts of organic manure levels and inoculation with mycorrhiza fungi on growth, quantitative and qualitative yield of hyssop (hyssopus officinalis l.), a field experiment was conducted as factorial based on a randomized complete block design with three replications at the agricultural research station, ferdowsi university of mashhad, during two growing seasons of 2009-2010 a...

Criconemella xenoplax, Fusarium solani, and F. oxysporum caused necrosis of Nemaguard peach feeder roots in greenhouse tests. Root necrosis was more extensive in the presence of either fungus than wtih C. xenoplax alone. Shoot growth and plant height were less for plants inoculated with F. oxysporum or F. solani than for plants inoculated with the fungi plus C. xenoplax. Neither synergistic nor...

Niche differentiation, assumed to be a key mechanism of species coexistence, requires that species differ in their functional traits. So far it remains unclear to which extent trait plasticity leads to niche shifts of species at higher plant diversity, thereby increasing or decreasing niche overlap between species. To analyse this question it is convenient to measure niches indirectly via the v...

ABSTRACT Flame retardants are efficient in fighting wildfire; however, their environmental implications, especially regarding the vegetation, need to be clarified. This work aimed at assessing effects of flame retardant on initial growth Schizolobium amazonicum. Treatments consisted applying different concentrations via substrate and leaf: Phos-Chek WD-881® (0, 3.00, 6.00, 8.00 10.00 mL L-1), H...

to study the effect of planting date on morphological characteristic, yield and essential oil content of achillea millefolium sub sp millefolium.l., an experiment in a randomized complete blocks design (rcbd) with four treatments including four planting date (6 july, 1 august, 7 september and 7 october) in four replications was conducted. during the growing stage and at the end of experiment pe...

The steppe peony (Paeonia tenuifolia L.) is an endangered medicinal plant species that occurs in Serbia three habitats, of which the Deliblato Sands richest. Based on results research conducted at 2023, it was found development flowering stems Paeonia not affected by slightly higher average winter temperatures. One hundred randomly selected plants were measured field, including height, girth, n...

The influence of temperature and olive root exudates on Heterodera mediterranea egg hatch and the effects of H. mediterranea on the growth of two olive cultivars (Arbequina and Picual) were investigated. Egg hatch occurred over a temperature range of 10 to 30 degrees C and was optimal at 20 to 25 degrees C. There were no differences in egg hatch between sterile deionized distilled water or root...

Micropropagation protocol of Pimpinella candolleana an important ethno medicinal herb has been developed for the first time. High frequency plantlet regeneration was achieved from shoot tip explants of P. candolleana. Effect of growth regulators in different concentrations and combination of BAP, KN, NAA, IAA and IBA on in vitro morphogenesis was tried. The highest regeneration response was obs...

Unlike many wild grasses, domesticated rice cultivars have uniform culm height and panicle size among tillers and the main shoot, which is an important trait for grain yield. However, the genetic basis of this trait remains unknown. Here, we report that Dwarf Tiller1 (DWT1) controls the developmental uniformity of the main shoot and tillers in rice (Oryza sativa). Most dwt1 mutant plants develo...
