abstract one basic method of improving rangelands in a country is the use of native as well as exotic species of plants adaptable. among the but introduced species, atriplex canescens has been introduced in many rangelands, but it is important and necessary to consider it’s effects on native species. in the current study the effect of chemical competition (allelopathy) of atriplex canescens on ...

The primary purpose of this study was to examine the effects virus infection in Phalaenopsis cultivated across country. RT-PCR analysis used detect two major viruses orchid: CymMV and ORSV. rate vitro plantlets from 45 cultivars 83.6%, potted plants 21 92.5%. For CymMV, single 34.3%, for ORSV, it 11.4%. In case plants, with 57.0%, ORSV alone not detected. double both viruses, accounted 37.9% 35...

Pecan [Carya illinoinensis (Wangenh.) K. Koch] trees developed necrotic areas in the leaves late in the growing season. July samples indicated that leaf P (0.114% DW) and K (0.62% DW) were low, but other elements were within accepted sufficiency ranges. Relationships between leaf P and K concentrations with nut quality and return bloom were determined. Trees were rated for leaf necrosis 1 Octob...

A viral disease causing severe mosaic, necrotic, and yellow symptoms on Vigna angularis var. nipponensis was prevalent around Suwon area in Korea. The causal virus was characterized as Cucumber mosaic virus (CMV) on the basis of biological and nucleotide sequence properties of RNAs 1, 2 and 3 and named as CMV-wVa. CMV-wVa isolate caused mosaic symptoms on indicator plants, Nicotiana tabacum cv....

Leaves of tomato cultivars that contain the Pto bacterial resistance locus develop small necrotic lesions within 24 hr after exposure to fenthion, an organophosphorous insecticide. Recently, the Pto gene was isolated and shown to be a putative serine/threonine protein kinase. Pto is one member of a multigene family that is clustered within a 400-kb region on chromosome 5. Here, we report that a...

Oleander (Nerium oleander L.) is a popular woody ornamental plant, often used for decorating public areas, terraces and gardens. Many diseases may decrease in the value of these plantings. Between 2018 2020, plant pathogenic bacteria were examined, many samples infected plants collected from different sites Hungary. Two non-pigmented Serratia marcescens isolates identified by classical molecula...

using iMap-IVUS and OCT. They defined OCT-TCFA as lipid-rich plaques with <65 mm-thick fibrous caps, which were subsequently identified in 22 (26%) lesions. Significantly larger percentages of necrotic area, absolute lipidic and necrotic areas, and a smaller percentage of fibrotic area were found in OCT-TCFA than in non-TCFA. Multivariate analysis showed that absolute necrotic area was an indep...

Extraordinary importance of Date-Palm, Phoenix dactylifera especially ‘Piarom’ variety and also undeniable effect of nitrogen and phosphorus on yield and quality of this product, caused this research to be accomplished. The research was performed during two years on 72 (4*3*3*2=72 trees) fruitful, 12 years old trees in Hormozgan province. Treatments were consisted of four levels of nitrogen (0,...

We report a case of a rare complication of laparoscopic adjustable gastric banding (LAGB) as a cause of death in the immediate post-operative period. The number of relevant reports and postmortem images presented in the literature is extremely restricted. Gastric necrosis may constitute a cause of death after LAGB in the early post-operative period. Postmortem examination reveals the extension ...
