Studies on the effect of simulated acid raid rain (pH 2.0, 3.0, 4.0, 5.0 and control pH 5.6) growth, yield mineral nutrient relations Capsicum frutescens (chilli pepper) was carried out. Simulated (SAR) prepared by adding sulphuric nitric in ratio 3:1 to distilled water get desired pH, sprayed plants. The experimental result indicated that under stress rain, growth parameters which include plan...

Physalis is an herbaceous species native to the Andes region. Currently, it cultivated in various Brazilian states due economic interest of growers for this new fruit. plants grown field showed symptoms shoot proliferation, leaf malformation, and chlorosis. Since these are commonly induced by phytoplasmas, study investigated confirm presence prokaryotes symptomatic plants. After DNA extraction ...

Peanut/maize intercropping is a sustainable and effective agroecosystem to alleviate iron-deficiency chlorosis. Using suppression subtractive hybridization from the roots of intercropped and monocropped peanut which show different iron nutrition levels, a peanut gene, AhNRAMP1, which belongs to divalent metal transporters of the natural resistance-associated macrophage protein (NRAMP) gene fami...

Tomato chlorosis virus (ToCV), and Tomato infectious chlorosis virus (TICV), family Closteroviridae, genus Crinivirus, cause interveinal chlorosis, leaf brittleness, and limited necrotic flecking or bronzing on tomato leaves. Both viruses cause a decline in plant vigor and reduce fruit yield, and are emerging as serious production problems for field and greenhouse tomato growers in many parts o...

We investigated for 2 years (1995–1996) the time course development of chlorosis and the variation of iron (Fe) content in vegetative and reproductive organs in two nectarine orchards planted with cv Spring Red and cv Stark Redgold on calcareous soils of the Po valley (Italy) with the final aim to evaluate possible tools for the early prognosis of Fe chlorosis and a more efficient fertilization...

Digital images of soybean canopies/Glycine max (L.) Merrill] were obtained within selected narrow wavebands (6-1 O nm bandwidths) to determine their capability for early detection of plant stress. Images and physiological measurements of stress were acquired 2 days, 4 days, and 7 days following application of control, drought, and herbicide [(3,4-dichlorophenyl)-l, I-dimethylurea, or DCMU] trea...
