Direct axillary shoot regeneration from the mature seed explant of the hairy vetch (Vicia villosa Roth)

Effects of Rhizobium Inoculation on Nitrogen Fixation and Growth of Leguminous Green Manure Crop Hairy Vetch (Vicia villosa Roth)

Cropping history affects nodulation and symbiotic efficiency of distinct hairy vetch (<i>Vicia villosa</i> Roth.) genotypes with resident soil rhizobia

Compatible rhizobia strains are essential for nodulation and biological nitrogen fixation (BNF) of hairy vetch (Vicia villosa Roth, HV). We evaluated how past HV cultivation affected nodulation and BNF across host genotypes. Five groups of similar HV genotypes were inoculated with soil dilutions from six paired fields, three with 10-year HV cultivation history (HV+) and three with no history (H...

Contribution of ammonium to stimulation of smooth pigweed (Amaranthus hybridus L.) germination by extracts of hairy vetch (Vicia villosa Roth) residue

Hairy vetch is a leguminous winter annual cover crop that provides a significant contribution toward meeting the nitrogen requirement of succeeding crops. Hairy vetch residue is capable of suppressing weeds, but low levels of residue can intermittently stimulate the emergence of weeds, particularly smooth pigweed. This research was conducted to assess the inhibitory and stimulatory effects of h...

the survey effect of bap and tdz on direct shoot regeneration from nodal explant of agastache foeniculum

the first successful and an efficient regeneration system on in vitro direct plant regeneration of agastache foeniculum was reported. the experiment were done in factorial design with three replications and explants were cultured in ms media fortified with different concentrations of bap and tdz (0, 2.2, 4.4, 8.8 μm) in combination with 3 levels of iaa (0, 1.1 and 2.2 μm). anova analysis showed...

Influence of Explant Nodal Positions on the In Vitro Shoot Regeneration of Rose

The influence of explant nodal positions on the in vitro shoot growth and proliferation were studied in the two rose cvs. ‘Bianca’ and ‘El Torro’. Third, fourth and fifth nodal explants were cultured on the modified MS medium supplemented with 1.0 and 5.0 mg/l BA. In both the cultivars, higher rate of proliferation (‘Bianca’ 3.75; ‘El Torro’ 2.65) were obtained from the explants distal to the a...
