Download scientific diagram | Análisis mendeliano de la autofecundación de una planta transgénica, que porta una copia del transgene que confiere tolerancia. A utilização da AI no melhoramento de plantas é feita há bastante tempo, mas .. a auto-incompatibilidade possa limitar a possibilidade de se autofecundar e. En Fitogenetecnia, se refiere a al capacidad de autofecundación de una planta, o al cruzamiento entre plantas, sin existir impedimento genético, morfológico o.

Self-incompatibility in plants

Both stalk height and stalk weight showed to autofecunndacion subjected to fairly strong inbreeding depression. Noutros proxectos Wikimedia Commons. Precision requires that the term self-pollination be restricted to those plants that accomplish pollination without an external pollinator. The language you choose must correspond to the language of the term you have entered. George, BB, Barbados, W.

Por exemplo, em trevo vermelho Trifolium pratense estima-se haver em torno de diferentes alelos enquanto o trevo branco teria em torno de alelos diferentes no loco S LAWRENCE, The Journal of Heredity, v. The Plant Cellv.

In the pioneer research, the most spectacular yield increases were obtained by using hybrids involving two or more selfed lines in maize. Existen mecanismos que impiden ou reducen a autogamia nas anxiospermas, tales como a autoincompatibilidadea heterostiliaa hercogamia e a dioecia.

The lowest frequency of superior offspring in relation to average parents was observed in the segregation for stalk weight. Apomixis in higher plants. For the inbreeding depression occurrence, besides heterozigosity in the locus, plahtas should be dominance and or epistasis in the character control.

Soluble solids means were obtained by direct sugarcane juice readings in ten and eight randomly chosen stalks from self and autofecundackon respectively. Inbreeding depression estimates allow the inference of population genetic structure and predominant gene action in the genetic control of characters. A hand refractometer was used to determine the rate of soluble solids in the cane juice.
