...h somatic embryogenesis (cotyledon and hypocotyl) for callus induction followed by shoot and root regeneration of Brassica carinata. Seeds were sterilized and germinated, of which one week cotyledon and hypocotyl were used for callus formation and shoot regeneration at five different level of 1-naphthaleneacetic acid NAA (0.05, 0.1, 0.5, 1.0 and 1.5 mg/l) and 6-benzyl amino purine BAP (0.1, 0.5, 0.7, 1.0 and 1.5 mg/l), and r...

The study was conducted to observe the effect of genotypes, culture conditions and growth regulators on plant regeneration of chili pepper genotypes (Seedex Pepper (SP), Loungi, Tatapuri, and Sanam) grown in Pakistan including. For both hypocotyl and cotyledon explants, SP was found to be the most sensitive among the tested genotypes tested. Maximum mean callus ind...

Results showed significant differences in plant responses wherein the application of GA3 resulted in the longest vine length at the two-leaf stage (3.24 m) and enhanced the staminate flower production. Ethrel enhanced pistillate flower tendency and improves yield when applied at cotyled...

CMV was able to infect only 20 plant species and varieties out of 24 tested plants by either grafting or mechanical inoculation, and PPV was able to infect only 19 plant species and varieties. CMV and PPV can be transmitted by Aphis gossypii and Myzus persicae from cucumber to cucumber and woody plants. Th...

PNRSV was able to infect only 12 plant species and varieties from 19 by grafting or mechanical inoculation, it has a limited range of experimental hosts. The dilution end-point of infectivity was 10-3, the thermal inactivation point was 540C, and longevity in vitro was of 10-14 h at 250C. PNRSV was detected...

However, the specific effects of tannic acid on reproduction and its underlying mechanisms are still poorly understood. Therefore, this study explored the effects of tannic acid on the reproduction of Brandt’s voles. We treated female Brandt’s voles from four weeks postpartum with varying tannic ac...

Cotyledon assay was negative for isolates from Mansehra (MNS2); whereas, MNG1 isolate didn't produce any symptoms for all three tests. Old seedlings test was negative for four isolates mainly; MKD2, MNG1, DIK1 and NWS2. To investigate the h...

Essential oils from both healthy and infected plants were extracted through hydro distillation and subsequently analyzed using GC-MS. Notable alterations in the essential oil composition due to viral infection were recorded. The principal constituents identified were methyleugenol and p-cresol, 2,6...
