Meaning of “fototropismo” in the Portuguese dictionary

CurtisBarnes, Schnek, Flores. Effects of light, growth media, and seedling gravitrolismo on biossays of alfalfa autotoxicity. Environmental and Experimental Botany Gravity sensing, a largely misunderstood trigger of plant orientated growth.

E, ancora, possiamo parlare di fototropismodi macchina dei sogni, di lirico illusionismo e nel contempo, con la magia dell’emozione, di una perfetta restituzione As reported before Di Benedetto et al. In untreated climbing plants, the epidermal cell layer represented a larger fraction of leaf cross-section than in either creeping or hanging ones.


However, when comparing climbing plant with plants hanging freely from a pot, an alternative or complementary explanation of the morphologic gravitropsmo of Golden Pothos to vine orientation may be given. Elsevier-Academic Press, 2 nd edition. American Journal of Botany Influence of horsenettle Solanum carolinense on snapbean Phaseolus vulgaris.


Golden Pothos varieties are among the most popular tropical ornamental hanging basket crops for interior landscape. Chemicals were of highest purity Sigma-Aldrich Co.

Combined effect of exogenous auxin and cytokinin on Epipremnum aureum growth and leaf area development. Journal of Fruit Science Care was taken to ensure similar light exposure to the plants regarding the training system employed. These results, taken together, may be a response to a possible growth regulator both auxin and cytokinin deficiency in creeping and, especially, in hanging plants.

Variation in LAR was in general low, climbing plants tend to present higher values than either creeping or hanging ones.

Journal of Chemical Ecology The present work was aimed at studying plantaa exogenous auxins and cytokinins may influence growth of E.

Exogenous growth regulators supply could then restore decreased endogenous hormonal levels in plants due to vine departure from vertical upward position. Growth regulators-treated plants also showed higher RGR values, which could be explained mainly because of a strong promotion in NAR by both auxin graviitropismo cytokinin.


These results are in good agreement with previous work on creeping E. For the germination experiments the number of germinated seeds was checked every 8h.

It is well known that thigmomorphogenetic responses are modulated by hormone homeostasis and especially by distribution patterns of auxins Chehab et al. Mean net assimilation rate NAR was calculated as:.

Leaf size depends, among other factors, on how vines are trained. The application of IAA or BAP at any concentration, either in single or combined manner, led to a significant increase in final FW in creeping and hanging plants, but not in climbing ones. Temperature-dependent germination and endo-b-mannase activity in sesame seeds. Pedaliaceae under different temperatures.
