Neem (Azadirachta indica) belongs to the Meliaceae family. is well-known around world for its medicinal and nutritional properties. Various parts of plant like fruits, leaves, flowers, twigs, gum, seed, oil, bark, root are known have properties scientifically established various Since ancient times, plant’s been utilized their value. The contains a high amount catalase (CAT), peroxidase (POD), ...

Silicone and Glutathione application are including systemic acquired resistance or induced against plant diseases against. It is a successful means to control rot disease it leads fundamental effects on the physiology of host, as use in agent hostile Fusarium solani causal Broad bean root .The results this study appeared that have make less tot incidence severity plants increase resistance-Link...

This work describes, for the first time, the changes taking place in the antioxidative system of the leaf apoplast in response to plum pox virus (PPV) in different Prunus species showing different susceptibilities to PPV. The presence of p-hydroxymercuribenzoic acid (pHMB)-sensitive ascorbate peroxidase (APX) (class I APX) and pHMB-insensitive APX (class III APX), superoxide dismutase (SOD), pe...

Objective: Polyphenol oxidase or PPO (EC 1.14.18.1) is considered the enzyme responsible for quality deterioration and browning in different fruits during postharvest period. The objective of this study was to evaluate the antibrowning (inhibition of polyphenol oxidase activity) effect of Cysteine, Ascorbic acid, citric acid, kojic acid and glycine at two different pH (6 and 7) in  hawthorn. Me...

Most damaging plant diseases have been caused by viruses in the entire world. In tropical and subtropical areas, damage virus leads to great economic agricultural losses. Single stranded DNA (geminiviruses) are most perilous pathogens which responsible for major agronomic horticultural crops. Significantly begomoviruses mastreviruses biggest genus of infecting viruses, transmitted though Bemisi...

Two faba bean, Vicia faba L., cultivars, Gazira2 and Misr1, representing cultivars moderately resistant and susceptible to aphids, were analyzed for peroxidase (POD) and polyphenol oxidase (PPO) activities induced by cowpea aphid, Aphis craccivora Koch. infestation. Two tissue types (whole plant [WP] and detached leaf [DL]), two infestation status (infested and uninfested), and three aphid infe...

root-knot nematodes (meloidogyne spp.) are among the most important groups of plant-parasitic nematodes, causing damage and yield losses to most cultivated plants. the bacterium pseudomonas fluorescens cha0 and the fungus trichoderma harzianum bi were investigated for biological control capability and systemic induction of resistance against the nematode m. javanica under glasshouse conditions....

Adaptation and defense responses are the consequences of exposure to drought stress in plants. Salicylic acid (SA) as a natural signaling molecule poses a significant impacts on various aspects of plant growth and development. This study investigates the effects of SA on carotenoids content, lipid peroxidation rate and antioxidant enzymes activities. A pot experiment was conducted using a facto...
