COMPARATIVE STUDY OF DIFFERENT GROWTH REGULATORS FOR EFFICIENT PLANT REGENERATION IN GRAPES
...n vitro morphogenesis of grapevine accessions viz., 4494(1) Kowar Sufaid, 4472(12) Harker Agoon and 4492(1) Kowar Naray. When levels of benzylaminopurine (BAP) were increased in the basal MS media for culturing the grape plantlets, there was a corresponding increase in the number of shoots and root mass. Additionally, the shoot proliferation response to increasing level of BAP was found genotype dependent. Naphthaleneacetic acid (NAA) also showed a positive ef...

...Koch population from grapevine orchard indicated considerable survival on dicofol 18.5 EC, fenpyroximate 5 SC, diafenthiuron 50 SC, sulphur 80 WP, abamectin 1.9 EC, hexythiazox 5.45EC, spiromecifen 240SC, propargite 57% EC, ethion 50EC, fenazaquin 10%EC treated leaves. Field populations had high degree of resistance to Sulphur 80WG with LC 50 of 17769.72 ppm against 651.17 ppm for a laboratory susceptible strain. Thus 27.30 fold resistance ratio...

And from tomato exhibiting necrotic rings and sinuous lines symptoms. The virus was checked in the suspected samples by ELISA using the specific antiserum. Anatomical and ultrastructure changes in leaf tissues of both Tomato and

was carried out using mechanical inoculation into fourteen different diagnostic host plant species and
cultivars belonging to 6 families. Tomato seeds were treated with four different concentration of

...ring fruiting seasons of grapevine in 2012 and 2013. The nematodes encountered were identified as Meloidogyne spp., Helicotylenchus spp., Longidorus spp., Pratylenchus spp., Tylenchulus semipenetrans and Hoplolaimus spp. Community analysis of these plant parasitic nematodes showed variability in nematodes population densities, frequencies, biomass and importance values in different Districts during 2012 and 2013. Root-knot nematodes Meloidogyne spp. was the mo...

...edlings and rootstock of grapevine were selected from 6 vineyard from two districts of Balochistan,
Pakistan. Seven species of nematodes were found associated with the seedlings/rootstock including Aphelenchus avenae,
Helicotylenchus indicus, Hoplolaimus indicus, Meloidogyne javanica, M. incognita, Xiphinema americanum and X. index.
A matrix of similarity between six vineyard-nurseries was computed using Bray-Curtis index.

...ausing powdery mildew on grapevines is being reported in Pakistan. Infected plants were collected from districts Mansehra and Abbottabad of Khyber Pakhtunkhwa, and district Lahore of Punjab, Pakistan, during phytopathogenic surveys in 2015–2020. The causal fungus was observed and identified on the basis of morpho-anatomical and molecular analyses. This is the first report of powdery mildew infection caused by Erysiphe necator var. necator from Punjab and...

Three out or 25 samples were positive for GFLV by DAS-ELISA using specific polyclonal antibodies raised against purified GFLV preparation and five samples were positive by RT-PCR. RT-PCR detected GFLV in both fresh and dried tissues. A fragment (321 bp) of the coat protein gene of GFLV was amplified by reverse transcription-polymerase chain reaction (RT-PC...

In the present study, direct tissue-printing and dot-blot on the membranes, procedures has been applied on a large scale for an initial screening of HSVd, CEVd and PSTVd in Egypt. The results showed that the tissue print assays allowed clear discrimination between healthy and viroid-infected grapevine plants than dot-blot hybridization, the numb...
