The Trialeurodes vaporariorum first instars (crawlers) are mobile and able to choose the optimal spots on leaf for 
 constant feeding favorable pest development. Spatial distribution of larvae adults cucumber Ginga F1 cotyledon leaves, as well morpho-anatomical structure cotyledons cross sections have been studied in laboratory. Some differences topology sites between were revealed. Female...

One of the main causes worldwide decrease sowing quality soybean seeds is a cotyledonous bacterial blight in form necrotic decaying spots on outer or inner side cotyledons. We hypothesize that there primary non-bacterial cause for development cotyledons seeds. carried out research 2016-2020 at V.S. Pustovoit All-Russian Research Institute Oil Crops Cotyledonous never recorded immature healthy p...

Using cotyledons of 2-week old in vitro germinated seedlings, a rapid and efficient regeneration protocol was established for A. mangium on Murashige and Skoog (MS) basal medium. Cotyledons showed better direct shoot organogenesis producing maximum 10.88 ± 0.35 shoots per explant when cultured on MS medium supplemented with 2.0 μM BA and 1.0 μM NAA. Full strength of MS medium supplemented with ...

Colonization and infection of soybean cotyledons by Agrobacterium tumefaciens and subsequent elimination of bacteria from cotyledons were monitored using bacteria expressing green fluorescent protein (GFP). GFP provided a quick, non-destructive method to evaluate, in real time, Agrobacterium colonization of cotyledon surfaces as well as infection of internal cells. GFP was first detected 7 h fo...

ewe abortion and neonatal mortality are serious problems to sheep farmer. the objective of this paper was to report isolation of erysipelothrix rhusiopathiae from aborted fetuses in a flock in tehran, iran. abortion occurred in 10% of ewes in the flock. the fetuses were well developed and pinpoint, necrotic-like lesions were recorded on the placental cotyledons, whilst the inter -cotyledonary a...
