abstract in vitro leaf explants of gf677 hybrid rootstock and rabi cultivar were placed on mql medium supplemented with bap at 0, 1, 2, 3 and 4 mg/l and naa at 0, 0.15 and 0.3 mg/l concentrations. the results revealed that bap, naa, genotype and their interactions had significant effect on both percentage and mean number of the regenerated shoots. for gf677, the highest percentage of shoot rege...

Ildole 3 butyric acid (IBA) at 8rng l i induced, vigorous rooting in Bupleurum falcatum L. (Saiko) root culture in B5 medium after about 2weeks, when it was added at the time when detached roots were transferred to fresh medium. The rooting activity markedly decreased with delay of IBA addition after root 2transplantation, and was hardly observed when IBA was added at the 7th day. Stresses such...

In forest production systems, vegetative propagation of elite clones through adventitious rooting is a common practice. In Chile, adventitious rooting is the main methodology for vegetative reproduction of Pinus radiata. However, the capability of produce adventitious roots in gymnosperms decreases with aging. While it is true that some efforts have been made to identify markers or/and regulato...

The two-layer hypothesis of tree-grass coexistence posits that trees and grasses differ in rooting depth, with grasses exploiting soil moisture in shallow layers while trees have exclusive access to deep water. The lack of clear differences in maximum rooting depth between these two functional groups, however, has caused this model to fall out of favor. The alternative model, the demographic bo...

the purpose of this study was to compare rooting methods in tissue culture regenerated-clones in sugar beet and their adaptation to environmental conditions and determine clones ploidy stability. two kinds of explants including shoot apex of seedlings and inflorescence stem pieces were used for preparation and propagation of the clones in media. in the next step, three rooting and adaptation me...

Abstract Ornamental black mulberry (Morus nigra L.) is used in landscape. which has high shade, tolerates air pollution and wind. White alba proper for kind of soils conditions. Therefore, this research was conducted to investigate the effects stenting methods IBA levels on some characters scions onto white rootstock first time. For purpose, an experiment carried out as factorial completely ran...

Semi-hardwood cuttings of ‘Frantoio’ (high rooting ability) and ‘Gentile di Larino’ (low rooting ability) cultivars were obtained from 1-year-old olive shoots sampled in mid-August during the 2000 and 2001 growing season. Semi-hardwood cuttings were dipped in IBA 4000 ppm and H2O2 (0%-control or 3.5% w/v) solutions before rooting in greenhouse equipped with an automatic mist system. At 57 and 8...

Abstract The objective of this work was to evaluate the effects indolebutyric acid (IBA) concentration, substrate composition and volume, propagule type on adventitious rooting quality Cordia trichotoma plantlets produced by mini-cuttings. Mini-cuttings were evaluated for percentage root number length at 30 60 days cultivation. Plantlets shoot height stem diameter 30, 60, 90, 120 Dickson index,...
