This research was aimed to study the interest of flower analysis as a tool for the prognosis of nutritional deficiencies on cherry trees and confirm the influence of rootstock on the mineral uptake by tree. This type of diagnosis is compared with foliar analysis. The trial was established on a calcareous clay-loam soil, where ‘Sunburst’ cultivar on eight rootstocks: CAB 6P, CAB 11E, Masto de Mo...

BACKGROUND The vegetative phenotype of the pea mutant unifoliata (uni) is a simplification of the wild-type compound leaf to a single leaflet. Mutant uni plants are also self-sterile and the flowers resemble known floral meristem and organ identity mutants. In Antirrhinum and Arabidopsis, mutations in the floral meristem identity gene FLORICAULA/LEAFY (FLO/LFY) affect flower development alone, ...

lehmannia valentiana is one of the most important pests of ornamental plants, vegetables and other agricultural crops, which causes noticable damages. in a food experiment four kinds of food for 24 and 72 hours were offered. the preferences of food were amaranthus tricolor, cineraria grandiflora, pelargonium peltatum, rosa damascena and l. valentiana. the l. valentiaiia is active the whole year...

We report the chemopreventive activity of Acacia nilotica (Linn.) gum, flower and leaf aqueous extracts, on 7,12-dimethylbenz(a)anthracene (DMBA) induced skin papillomagenesis in male Swiss albino mice. Animals were divided into following groups: Group I (Controls) given DMBA and croton oil, with no extract ; Group II (treatment) animals treated with Acacia nilotica gum (Group II-a) (800 mg/kg ...

The volatile constituents of the essential oils of the peel, flower (neroli) and leaves (petitgrain) of bitter orange (Citrus aurantium L.) growing in Greece were studied by GC-MS. The analytical procedures enabled the quantitative determination of 31 components. More specifically, the components of the essential oils identified were: twelve in the peel, twenty-six in the flowers, and twenty an...

Tipuana tipu (Benth.) Kuntze is a tree from the leguminosae family (Papilionoideae) indigenous in Argentina and extensively used in urbanism, mainly in Southern Brazil. The epicuticular waxes of leaves and branch, and flower surface were studied by high temperature high resolution gas chromatography. Several compounds were characterized, among which the aliphatic alcohols were predominant in br...

Ethrel, a mixture of 2-chloroethanephosphonic acid and its ethyl ester, hastens abscission of leaves, debladed petioles, and flower buds of cotton plants (Gossypium hirsutum, L.). Both young and old leaves abscissed while still green. Application of Ethrel stimulated evolution of ethylene, and this response preceded abscission. Air concentrations of ethylene around enclosed, treated-plants were...

In Primula vulgaris outcrossing is promoted through reciprocal herkogamy with insect-mediated cross-pollination between pin and thrum form flowers. Development of heteromorphic flowers is coordinated by genes at the S locus. To underpin construction of a genetic map facilitating isolation of these S locus genes, we have characterised Oakleaf, a novel S locus-linked mutant phenotype. We combine ...

YABBY and WUSCHEL-LIKE HOMEOBOX (WOX) genes have been shown to play important roles in lateral organ formation and meristem function. Here, we report the characterization of functional relationship between rice (Oryza sativa) YAB3 and WOX3 in rice leaf development. Rice YAB3 is closely related to maize (Zea mays) ZmYAB14 and Arabidopsis (Arabidopsis thaliana) FILAMENTOUS FLOWER (FIL), whereas r...
