Emergence of Groundnut ringspot virus and Tomato chlorotic
spot virus in Florida and the southeastern United States.
The second evidence of coinfection between 'Cotton leaf curl burewala virus' (CLCuBuV), a begomovirus with dicot infecting mastrevirus;'Chickpea chlorotic
dwarf virus' (CpCDV) was reported by Manzoor et al.
spots were observed and later coalesced to form blotches.
The top sides of the leaves display the characteristic dark stippling, while the leaf in the back is chlorotic
and may soon drop.
Phosphatase activities of both cultivars were similar to that of chlorotic
For example, in Huysmans's "Ballade Chlorotique" in Le Drageoir aux epices (1874), a similarly chlorotic
"Phtisie" lures her victims into a danse macabre (Le Drageoir aux epices 119), prefiguring the allusion to the des Esseintes family, fully ten years before A rebours.
Anyone with family or friends gardening on the chalk downs of southern England, or similar geological localities, is likely to be given a chlorotic
rhododendron, its leaves turning yellow as its chlorophyll-making processes fail on the alkaline soil.
Fontenelle M, Luz D, Gomes A, Florentino L, Zerbini F, Fontes E (2007) Functional analysis of the naturally recombinant DNA-A of the bipartite begomovirus Tomato chlorotic
For example, in the case of apple explants, a total inhibition of shoot regeneration from foliar explants has been observed and the tissues turned chlorotic
, and eventually necrotic, with 5 mg [L.
The grades are as follows: 0 = No infection (Highly resistant),1 = Few minute lesions on leaves (Resistant), 2 = Black lesion with no distinct chlorotic
halos covering [less than or equal to] 10% of the leaf area (Moderately resistant), 3 = Typical lesions surrounded by distinct chlorotic
halos covering 10-50 % of the leaf area (Moderately susceptible), 4 = Severe lesions on leaves with ample necrotic zones drying over part of the leaf, covering > 50 % of the leaf area (Susceptible), 5 = Severe infection, drying of the leaf spike infected to some extend (Highly susceptible).
The healthiest gardenias I had seen locally received either morning or filtered sun, such as that provided in a narrow side yard between two houses, and still had their fair share of yellowing, chlorotic
At first, the spikelets may appear water-soaked and chlorotic
(yellowing of plant tissue), but they change to a pinkish-red color.
