Eugenia uniflora is a species that presents great phytochemical variability, due to its main form of propagation, the seminal, which makes cultivation this commercial crop unfeasible. Therefore, objective work was develop protocol for vegetative propagation by stem cuttings. Substrates (Tropstrato®, vermiculite and sand), indolbutyric acid concentrations, rejuvenation methods (drastic pruning m...

A regeneration protocol ensuring a high frequency rooting of micro-shoots derived from apical and axillary buds of suckers of banana cv. Sagar was achieved by using liquid medium. When the explants were cultured on MS medium supplemented with 0.5 mg/l each of BA, Kn and NAA, a large number of shoots developed. With the progression of the number of subcultures, shoot proliferation was enhanced. ...

Vitamins are necessary compounds synthesized and utilized in plants. In tissue culture media, vitamin addition is not always common; since the amount needed by plants is relatively unknown and varies. Vitamins, in combination with other media constituents, have been shown to have direct and indirect effects on callus growth, somatic growth, rooting, and embryonic development. For example, diffe...

This study was conducted to evaluate the effect of plant growth regulators on in vitro shoot multiplication, vitrification and rooting of two carnation cultivars (Eskimo Mogr and Innove Orange Bogr). Isolated axillary buds were cultured on MS medium supplemented with different levels of Benzyl amino purine (BAP) or kinetin (Kin) in combination with 0.2 mg/l NAA and shoot multiplication and vitr...

ABSTRACT Background: Despite the importance of Plathymenia reticulata for forestry and ecological purposes, a protocol vegetative propagation species remains unclear mainly due to low adventitious rooting propagules species. In this sense, work aimed evaluate mini-cuttings juvenile materials P. our hypothesis: (1) maintaining under mist chamber different periods affects process; (2) mini-stump ...

In vitro rooting as one of the most critical steps micropropagation is affected by various extrinsic (e.g., medium composition, auxins) and intrinsic factors species, explant). Passiflora in adventitious a difficult, complex, non-linear process. Since multivariable complex biological process, efficient reliable computational approaches such machine learning (ML) are required to model, predict, ...

ABSTRACT: Cedrela fissilis is a species of great genetic diversity, with low population density and seminal propagation, which causes difficulties in the vegetative propagation process. This research evaluated rescue stem cutting rooting originated from epicormic canopy sprouts C. fissilis. For this, induction was 52 days after complete girdling semi-girdling 20 40 cm ground, no treatment, duri...

Chrysanthemum has been commercially propagated by rooting of cuttings, whereas the quality will decline over multiple collections from a single plant. Therefore, we compared the vigour, rooting ability, and some physiological parameters between cuttings harvested from nongrafted "Jinba" (non-grafted cuttings) with those collected from grafted "Jinba" plants onto Artemisia scoparia as a rootstoc...

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...

There are two general types of rooting systems in extant land plants: gametophyte rhizoids and sporophyte root axes. These structures carry out the rooting function in the free-living stage of almost all land plant gametophytes and sporophytes, respectively. Extant vascular plants develop a dominant, free-living sporophyte on which roots form, with the exception of a small number of taxa that h...
