Scrutinizing of different aspects in vegetative propagation of Iranian J. communis L. is of prime importance in order to prevent extinction of such valuable conifer. In this research, the effects of different seasons, gender, different chemical compounds (IBA, PBZ, putrescine and sodium nitroprusside) and three strains of Agrobacterium rhizogenes on ex-vitro rooting c...
Rubber tree (Hevea brasiliensis) self-rooting juvenile clones (JCs) are promising planting materials for rubber production. In a comparative trial between self-rooting JCs and donor clones (DCs), self-rooting JCs exhibited better performance in rubber yield. To study the molecular mechanism associated with higher rubber yield in self-rooting JCs, we sequenced and comparatively analyzed the late...
using apple clonal rootstocks is necessary for improving crop efficiency in apple orchards. after graftingof apple cultivars on malling rootstocks, the extra parts of the rootstock was used as stem cuttings. apical,middle and basal parts of these shoots were used as cuttings. two propagation conditions, greenhouse andnursery and three concentrations of indole-3- butyric acid (iba) on rooting, c...
It was investigated whether skeletal muscle K(+) release is linked to the degree of anaerobic energy production. Six subjects performed an incremental bicycle exercise test in normoxic and hypoxic conditions prior to and after 2 and 8 wk of acclimatization to 4,100 m. The highest workload completed by all subjects in all trials was 260 W. With acute hypoxic exposure prior to acclimatization, ve...
This investigation was carried out at the Tissue Culture Lab., Biotechnology Research Center (BTRC) in Tripoli, Libya 2009 to establish a micro propagation protocol for two hybrids of Tomato which several factors were studied including effect concentration growth regulator on shoot multiplication, and rooting explant MS media. Shoot tips cultured into (MS medium) with different concentrations b...
Shoots of apple rootstocks raised in vitro were transferred to various rooting media to study the effect of different factors on root initiation and development. Various concentrations of indole-3-butyric acid (IBA) initiated rooting but maximum rooting percentage was found with 2.0 and 2.5 mg l(-1) of IBA in M7 and with 1.0 mg l(-1) of IBA in MM106. The drawback was that the roots were thick, ...
In this study, an experiment was carried out to determine the effects of 6 culture media (sand, perlite, vermiculite, Sand + Perlite, Sand + Vermiculite, Vermiculite + Perlite) on the rooting of single-bud cuttings of seven grape cultivars (Rishbaba, Hosseiny, Dashgarah, Ghiziluzum, Teberzeh, Bidaneh Sefid, Sahebi). All the cuttings were prepared from one-year old branches. Statistical analyses...

introduction: potential almond rootstock and thus main genetic sources for the breeding of its new rootstocks are almond itself, peach and plum, and these species cross-breeds almond is a source of resistance to limestone and to drought because of its roots, which reach deep layers of soil; it is also more resistant than peach to na and bo. asexual or vegetative propagation is a hereditable cha...
1. The effects of acclimatization temperature on the catalytic properties of acetylcholinesterase from rainbow-trout brain were examined. 2. Trout brain acetylcholinesterase occurs in two distinct forms. A single ;warm' variant of the enzyme is present after acclimatization to 17 degrees C; a single ;cold' variant appears after acclimatization to 2 degrees C. Both forms are present in fish afte...
