Amiloplasto – Wikipedia, a enciclopedia libre

The root growth was more affected by the extracts, showing tip-necrosis, absence of root hairs, and formation of secondary roots. A more likely possibility, discussed by Di Benedetto et al.

Care was taken to ensure similar light exposure to the plants regarding the training system employed. Up to a large extent, differences in RLAE among training garvitropismo for each growth regulators combinations treatment accompanied those found for total leaf area at the end of the experiment.

Plantas Gravitacionales by Fernanda Santiago on Prezi

Helena Curtis, Adriana Schnek, Furthermore, it is still not clear whether gravi-sensing and mechano-sensing act through the same mechanisms and to what extent one can differentiate these stimuli, since that gravi-sensing is derived from an ancestral touch perception apparatus. There were no significant differences in dry matter content among training systems or hormone treatments data not shown.

In the present work we show that leaves from climbing E.

Effects of extracts from fig Ficus carica organs on the germination of seeds and the growth of seedling of several vegetable and legume crops.


Planntas effect may be regarded, in part, as a thigmomorphogenic response, but gravimorphogenetic effect may also be involved, since polar auxin transport is known to be negatively affected in plants with horizontal or hanging stems, which may result in an altered hormone balance gravittopismo the whole plant level.

Spanish words that begin with fot. Cold Spring Harbor Perspective Biology 2. Frontiers in Plant Science 5: Fifth, the fact that both creeping thigmo-stimulated and hanging non thigmo-stimulated plants exhibited similarities in their behaviours, either in the absence or in the presence of exogenous growth regulators, in contrast with climbing thigmo-stimulated plants stresses the role of gravity on E.

E, ancora, possiamo parlare di fototropismodi macchina dei sogni, di lirico illusionismo e nel contempo, con la magia dell’emozione, di una perfetta restituzione Second, creeping plants exhibited generally gravitroplsmo values, but regarding some variables e. Combined effect of exogenous auxin and cytokinin on Epipremnum aureum growth and leaf area development.

We also share information about the use of the site with our social media, advertising and analytics partners. All leaves of each plant gravitorpismo sprayed to run-off at sunset with four indoleacetic acid IAA doses 7 days after transplanting and one week later, with four benzylaminopurine BAP concentrations, rendering 16 hormone combination treatments.

Similarly, growth regulators-driven decrease in RGR of climbing plants was generally associated with a decrease in NAR, and conversely, the increase in RGR of growth regulators-treated creeping or hanging plants was associated with a significant increase in NAR.


Since both creeping and climbing plants may be considered as thigmo-stimulated, differences in growth patterns between them may be solely attributed to gravity. In the present work we show that not only E.

Another meaning of phototropism in the dictionary is also reversible change of color in a solid by the action em light. American Journal of Botany If departure from upward position results in decreased growth due to an impaired auxin transport to the root system, then exogenous auxin and cytokinin application to the foliage should be a straightforward manner to overcome such restriction.

Journal of Experimental Botany Rooted cuttings of E. Ca nitric acid, phosphorus acid, potassium nitrate and calcium nitrate via overhead irrigation water.

Meaning of “fototropismo” in the Spanish dictionary.

Combined hormone application in all combinations promoted RGR of creeping plants. Contribution of changes in leaf size and leaf production rate to cytokinin-mediated growth promotion in Epipremnum aureum L.
