Root-knot nematode-susceptible melons (Cantaloupe) were grown in pots with varying levels of Meloidogyne incognita and were compared to susceptible melons that were grafted onto Cucumis metuliferus or Cucurbita moschata rootstocks. In addition, the effect of using melons as transplants in nematode-infested soil was compared to direct seeding of melons in nematode-infested soil. There were no di...

abstract in this study, interaction between amf (g. mosseae and glomus spp., respectively indigenous and non-indigenous of hm-contaminated areas) with cd-resistant pgprs (bacillus mycoides and micrococcus roseus, indigenous of contaminated areas) on the growth, cd and nutrient uptake of maize plant (zea mays l.) in cd polluted soil were investigated. with increasing levels of cd, shoot and root...

a hydroponic experiment was conducted to evaluate the effects of salt stress on safflower genotypes under greenhouse conditions. the experiment was arranged as a factorial one based upon a completely randomized design with three replications. five safflower genotypes (arak2811, nebraska10, sod25, ca116, and ca128), and four salinity treatments (0, 0.3, 0.5, and 0.7 percent of nacl) were employe...

The effects of soil temperature and initial inoculum density (Pi) of Meloidogyne incognito and M. javanica on growth of wheat (Triticum aestivum cv. Anza) and nematode reproduction were studied in controlled temperature baths in the glasshouse. Nematode reproduction was directly proportional to temperature between 14 and 30 C for M. incognita and between 18 and 26 C for M. javanica. Reproductio...

Thlaspi caerulescens J. & C. Presl is a distinctive metallophyte of central and western Europe that almost invariably hyperaccumulates Zn to > 1.0% of shoot dry biomass in its natural habitats, and can hyperaccumulate Ni to > 0.1% when growing on serpentine soils. Populations from the Ganges region of southern France also have a remarkable ability to accumulate Cd in their shoots to concentrati...

background: plants infection with microorganisms as well as physical factors such as osmotic stresses especially drought stress induced particular secondary metabolite production. objective: plant root and shoot hyoscyamine (hyo) and scopolamine (sco) variations were investigated under three water deficit stress (wds) levels as 30 (w1), 60 (w2) and 90 % (w3) water depletion of field capacity an...

Southwest of China is one of the major soybean (Glycine max L.) production regions in China with low availability of soil phosphorus (P). Whereas little information is available on P-efficient soybean genotypes in this region, even though using P-efficient soybean genotypes is a sustainable P management strategy for enhancing yield and P use efficiency. To assess the genetic variation on P use ...
