Objective: In vitro propagation of AZ x M9 new apple rootstock resulted of breeding program of vegetative apple rootstock in Iran was investigated. Methods: Nodal explants were inoculated in Murashige and SKoog (MS) medium supplemented with various concentrations of 6-benzylaminon purine (BAP) (0.4, 0.8 and 1.2 mg/l) alone or with naphthalene acetic acid (NAA) (0.1 mg/l). We examined t...
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
Hairy and adventitious roots are efficient systems for expressing recombinant proteins. In the present study, the amount of DrsB1-CBDAvr4 recombinant protein in hairy and adventitious root systems was compared. To this end, the effect of different factors on the optimization of culture conditions to obtain adventitious and hairy roots was evaluated in three separate experiments by assessment of...
ABSTRACT Gerbera (Gerbera jamesonii Bolus ex Hook. F.; Asteraceae), is one of the most economically important ornamental plants due to its aesthetic value. In present study, we established a micropropagation method for large-scale production quality planting material gerbera ‘Pink Melody’. Eighty-six percent capitulum explants produced adventitious shoots (15.44 ± 0.34 per capitulum) on Murashi...
in vitro multiple shoot regeneration of solanum nigrum l., an indian medicinal plant was accomplished on ms medium utilizing shoot tip and nodal explants. direct multiple shoots differentiated within 6 weeks when explants were cultured on ms medium containing bap (1.0-5.0 mg/l) and kin (1.0-5.0 mg/l) individually. among various concentrations of cytokinins tested, maximum number of multiple sho...
sericostoma pauciflorum stocks ex wight(family boraginaceae) used against cancer, diabetes and known to be health promoter. callus cultures have been established from the stem explants on murashige and skoog (ms) medium supplemented with 1.5 mg/l concentration of different growth hormone viz. kinetin (kn), indole 3-acetic acid (iaa) and indole 3-butyric acid (iba). at 6 weeks of age, these call...
