Vietnam has planning in re-forest of Chukrasia tabularis, a special-use forest and re-culture Coffea sp., an industrial crops. The first barrier is seedlings for supplying higher demand from farmers. Using thin cell layer culture method one the ways to resolve woody species. Results gave capacities using shoot-tips regeneration them far propagation. tabularis A. Juss: Shoot ti...

In many woody plants, shoots emerging from buds can develop as short or long shoots. The probability of a bud to develop as a long or short shoot relies upon genetic, environmental and management factors and controlling it is an important issue in commercial orchard. We use peach (Prunus persicae) trees, subjected to different winter pruning levels and monitored for two years, to develop and ca...

Bud break and multiple shoots were induced in apical and axillary meristems derived from one month old seedlings of S. mukorossi on Murashige and Skoog (MS) medium supplemented with benzylamino purine (BAP) 0.4 microM or 0.8 microM alone. A combination of BAP and gibberellic acid (GA3) 0.4 microM and 2.8 microM produced elongated multiple shoots from both types of explants. Excised shoots were ...

To elucidate the involvement of gibberellin (GA) in the growth regulation of Arabidopsis roots, effects of shoot-applied GA and GA-biosynthesis inhibitors on the root were examined. Applying GA to the shoot of Arabidopsis slightly enhanced the primary root elongation. Treating shoots with uniconazole, a GA biosynthesis inhibitor, also resulted in enhancement of primary root elongation, while sh...

The influence of temperature, shoot age, and medium on gall induction by Subanguina picridis on Russian knapweed (Acroptilon repens) was examined in vitro. The optimal temperature for gall formation was 20 C. Gall induction was delayed as the temperature decreased, and decreased as shoot age increased. Bud primordia (0-day-old shoots and 5-day-old shoots) with an average length of 4.2 mm and 7....

Two Zea mays cultivars, salt sensitive Trihybrid 321 and salt tolerant Giza 2, were studied, namely their adaptation to NaCl imposition at cell and whole plant level. Changes in growth and mineral content of roots and shoots, glycinebetaine (GB) and free proline (Pro) levels of shoots, plasma membrane permeability and solute potential (ø s) of leaf sheath subepider-mal cells were measured. NaCl...

The cactus Mammillaria gracillis Pfeiff. was propagated in vitro on Murashige and Skoog (MS) medium without any growth regulators. At the bases of some plants abundant callus masses developed. Lower agar and higher MS salt concentrations stimulated callus pro­ duction. In the culture, morphologically normal and hyperhydric shoots were regenerated. The growth of crown-gall tumour was induced on ...

With about 136 species, India is one among the richest countries in bamboo resources that help mankind in more than 1500 diverse ways. Although the utilization of juvenile shoots of bamboo in tribal diet of Northeast India is a very old observable fact, its numerous health benefits and potentiality remains uncharted. Apart from being delicious, the bamboo shoots are also rich in minerals and nu...

BACKGROUND AND AIMS This study analysed the differences in nitrogen (N), non-structural carbohydrates (NSC) and biomass allocation to the roots and shoots of 18 species of Mediterranean dwarf shrubs with different shoot-rooting and resprouting abilities. Root N and NSC concentrations of strict root-sprouters and species resprouting from the base of the stems were also compared. METHODS Solubl...
