Effectiveness of indoleacetic acid, indolbutyric acid and napthaleneacetic acid, during adventitious root formation
in vitro in Malus Jork 9.
Proliferated shoots were subcultured to MS medium containing different concentrations of auxin like NAA for root formation
It implies removing infected and inflamed coronal pulp tissue at the level of the entrance of the root canals and has been used in exposed carious or traumatized teeth with incomplete root formation
I chose the auxins naphthalene acetic acid (NAA) and indole butyric acid (IBA) for application in the cuttings experiment as they have been determined to be the most effective in initiating root formation
for the majority of rooting trials reviewed by Blazich (1988).
Cotyledons exhibiting hairy root formation
were removed from the plants and transferred to six-well culture plates (Costar Corp.
There was no root formation
at 60 days in the mini-cuttings grown in commercial substrate, vermiculite and sand and only 20% of rooting was observed at 90 days (Table 2).
Therefore, either IBA or NAA was required for root formation
from tung tree shoots.
Possibly the root formation
of regenerated Thermopsis shoots is affected by other unknown factors based on medium composition.
The effect of ethanol on root formation
in cuttings of Phaseolus aureus was associated with the production of ethyl- glucoside and carbohydrates in the presence of light (MIDDLETON et al.
It is thought to be caused by the failure of Hertwig's epithelial sheath diaphragm to invaginate at the proper horizontal level or changes in the mitotic activity of cells of the developing teeth that can affect root formation
(4) or influence from external factors on the development of the teeth (5) resulting in a tooth with short roots, elongated body, an enlarged pulp, and normal dentin (6) Previously, taurodontism was related to syndromes such as Down's and Klinefelter's syndrom.
Relationship between indole-3acetic acid levels in apple (Malus pumilla Mill) rootstocks cultured in vitro and adventitious root formation
in presence of indole-3-butyric acid.
Hypoxia promoted formation of crown (or adventitious) roots for the waterlogging-tolerant Jackson while it inhibited crown root formation
for the sensitive Bayles.
