Phylogenetic trees are routinely visualized to present and interpret the evolutionary relationships of the species that are being studied. Virtually all empirical evolutionary data studies contain a visualization of the inferred tree with support values using one of the popular and highly cited (e.g., TreeView, Dendroscope, FigTree, Archaeopteryx, etc.) tree viewing tools. As a consequence, pro...

two groups of olive cultivars were characterized as showing low (tokhmkabki) and high (roghani) rooting percentage after application of iba treatment. semi-hard wood cuttings were dipped in h 2 2 o 2 (0-3.5% w/v) and iba (4000 mg.l -1 ) and also they were investigated in combination. h 2 o 2 alone did not stimulate rooting of olive cuttings and there were no significant differences between this...

this research was aimed to investgate the effect of light quality on micropropagation of pear rootstock oh×f333. first, single nodes explants were cultured in modified ql medium containing ba at four levels (0, 0.5, 1, and 2 mg/l-1) and iaa at three levels (0, 0.1, and 1 mg/l-1) and were evaluated for shoot proliferation. then, plantlets subcultured in modified ql medium containing 1 mg/l-1 ba ...

This research aimed to explore the effect of zeatin (6-γ,γ-dimethylallyl-amino) concentration on in vitro shoot proliferation six olive (Olea europaea L.) cultivars, ‘Aggizi Shami,’ ‘Coratina,’ ‘Frantoio,’ ‘Manzanillo,’ ‘Picual,’ and ‘Toffahi.’ The cultivars were reproduced via multiplication Rugini medium (OM) with three concentrations (2, 4, 6 mg L-1) for subcultures. Shami’ ‘Toffahi’ had hig...

A fast, accurate and robust approach is proposed for the computation of the roots of complex polynomials. The method is derived from the DFT-based differential cepstrum estimation for moving average signals. This minimudmaximum-phase polynomial factorisation is easily extended to a factorisation along an arbitrary circle. In an iterative fashion, we estimate the largest root modulus from the di...

for vegetative propagation of nemaguard, st julien a, tetra and gf677 rootstocks via cutting, two separate experiments were carried out in a factorial based on completely randomized design. semi hardwood cuttings were taken in late august and then treated with concentrations of zero, 1500, 2000, 2500 and 3000 mg/l iba. cuttings were cultured in perlite medium and in a greenhouse with mist syste...

ABSTRACT- A detailed understanding of crop rooting systems will facilitate water use reduction, optimized nutrient uptake and irrigation scheduling more efficiently. A field experiment was conducted during 2005-2006 to investigate sugar beet rooting depth growth, irrigated with three irrigation methods (subsurface drip, surface drip and furrow) and two water qualities (recycled wastewater: EC= ...

Grindelia chiloensis (Asteraceae) is a shrub native to Patagonia, Argentina, in the process of domestication as a source of resin to complement rosin production by pines. Vegetative propagation to multiply selected genotypes has produced breakthroughs in the cultivation of new crops like jojoba (Simmondsia chinesis). The only available way to propagate Grindelia is by transplanting seedlings or...
