to study the effects of halopriming and hydropriming in overcoming salt and drought stress in corn (zea mays l.),two experiments were separately conducted at shahrood university of technology. seed treatments consisted ofcontrol (untreated seeds), soaking in distilled water for 32 h (hydropriming), and soaking in 50 mmol solution ofcacl2 for 16 h (halopriming). germination and early seedling gr...

The effects of Pratylenchus vulnus on growth and nutrition of Cadaman peach and Ishtara and Julior plum rootstocks were evaluated in a microplot experiment lasting two growing seasons. Cadaman peach was the only rootstock that showed suppressed growth for all growth parameters at the end of the first year. At the end of the second growing season, dry and fresh shoot weights as well as shoot len...

Hydroponic experiment was conducted to investigate the sole and combined effects of cadmium and salinity on growth and photosynthesis of Brassica napus (cultivar Abasin) and Brassica juncea (cultivar NIFA-Raya). Cadmium (as CdCl2; 3 and 6 μmol L) and NaCl (100 and 200 mM) were added either alone or in combination in Hoagland solution along with non-treated controls. Cd and NaCl treatments impos...

The effect of different concentrations of hexavalent Cr on growth and biochemical parameters of two T. aestivum cultivars (Punjab-11 and Sehar-06) was investigated. No significant inhibition of seed germination was observed in both the cultivars at all the tested concentrations (P ˃ 0.05). A significant decrease in root length for both the cultivars was observed at all the Cr concentrations as ...

The present study was conducted to investigate the allelopathic potential of Plumbago zyelanica L. which showed inhibitory effects on seed germination, root length and shoot length of medicinal plant Andrographis paniculata Nees. Leaf, stem and root aqueous extracts of P. zeylanica at 5%, 10%, 15%, 20% and 25% concentration were applied to determine their effect on seed germination and seedling...

For efficient regeneration of Petunia × hybrida F1 'Opera Supreme Pink Morn', a simple in vitro micropropagation protocol was developed. Axillary bud explants dissected from 30-day-old in vitro-grown seedlings sprouted from hybrid seeds were cultured on Murashige and Skoog (MS) medium supplemented with 36 combinations of 6-benzylaminopurine (BA; 0.00, 0.50, 1.00, 2.00...

drought preconditioning (dp) is a method of irrigation with low frequency and longer duration, to extend the root system and suppress drought damage in plants. in the present study, the effect of dp for 30 days on increasing tolerance to drought stress in two turfgrass species, creeping bentgrass (agrostis stolonifera cv.palustris) and tall fescue (festuca arundinacea cv. greystone) was investi...

In vitro budinduction and shoot regeneration of Lantana camara L. was investigated using axillary nodal explants. Multiple shoot buds were induced on Murashige and Skoog (MS) media supplemented with 0, 2, 4 and 8 mg/l of 6-benzylaminopurine (BAP) or thidiazuron (TDZ) for proliferation and 0, 0.25 and 0.5 mg/l indole-3 butyric acid (IBA) for rooting. After 4 weeks, a maximum number of shoot buds...

Earthen pots experiments were conducted for the evaluation of nitrogen fixing potential of three indigenous Bradyrhizobium japonicum isolates and one commercial inoculum (Narmada biofertilizer) in three commonly grown soybean cultivars viz., JS-335, JS-9305 and JS-7322. Nitrogen fixation was assessed in terms of root nodules number, root and shoot length and their dry weight. Results indicate t...
