Xenogamy The xenogamy tests were totally accomplished in 25 buttons emasculated before the dehiscence of the anthers. All the fruits obtained through each test had their fruits measured in length and their seeds were counted and separated. When the flower became 1. Apomixis in the angiosperms.

For each test, the following characters were appraised: Self-Incompatibility in Flowering Plants. Vistes Lleer Editar Editar la fonte Ver historial. Floral biology in the pre-anthesis phase The floral buttons with 0. Possibly, the competition for photo-assimilation is the main reason for the general position of fruits in the sub terminal area of the inflorescence, due to insufficient translocation of food for the terminal area of the inflorescence, generating the miscarrying of a great number of floral buttons and flowers.

There were larger amounts of starch in buttons below 1. Pollination mechanisms, reproduction, and plant breeding.

Meaning of “autogamia” in the Portuguese dictionary

William Collins Sons e Co. A esti procesu llamar pseudogamia. Natural pollination For this test, 30 floral buttons were marked with colored ribbon to verify the mean number of fruit produced under natural conditions. This is one of the requirements for the increment of the vegetable production, with the advantage of they present better condition to complete the biological cycle in adverse conditions.

The flowers of B. N’otros proyeutos Wikimedia Commons. The activity of the nectaries was evaluated every two hours, and the schedule of larger nectar production was evaluated through the observation of the polinators occurrence. The selection of self-fertilization.

The xutogamia placed on the stigma in the buttons with 0. In spite of these favorable characteristics for crop periods, few researches have been developed in Mato Grosso do Sul, although this species represents a great alternative for the State. In the second phase, the flower reached the mean size with 1. The floral buttons with 0. In agreement with the size of the hole, Trigona sp. Otra manera, el miceliu que presenta un solu nucleu haploide denominar monocarionte.

Alogamua and evolutionary biology of tropical flowers Cambridge tropical biology series. In the present work, it was observed that in artificial conditions xenogamy test, crossed pollination and smaller anthersthe size and the number of seeds were smaller Table 1.

Les espores haploides granen formando un protonemaque ye o bien una masa de filamentos o un talloide planu. Soon after, the pollen of the smaller anthers was taken on the stigma of the same buttons. Chrysomelidaeand Trigona sp. Brassica napusCanola, floral biology. The seed germination test was accomplished with five repetitions of ten seeds, except for autogamy where three repetitions were accomplished.

To observe the morphology of the flower and the sequence of events that precede the anthesis, 20 floral buttons were used in different development stages. In pre-anthesis, the buttons marked to evaluate the ragged time for the flower to reach the anthesis, it was observed that this was completed in about 20h, being the available rewards to the polinator for a mean period of 48h.

It was observed that B. November 23, ; Revised: The smaller anthers didn’t reach the stigma in this phase. This cutting was made in the place of nectar elimination and it enlarged progressively, resulting approximately in an circular opening, with a variable size.

This fact was confirmed through the sacking of the floral button and posterior transformation in fruit. Seeds of Brassica napus were used cultivar CTC-4sowed with spacing of 20 cm among the arrays and with 12 plants for linear meter. Columbia University PressNew York.

Alogqmia Mestrado Auyogamia de Janeiro. This happened probably, due to the manipulation accomplished in the floral button and in the stigma, during the emasculation and the pollen deposit. The anthers were observed under magnifying glass to verify the dehiscence type and the beginning of this process was correlated with the stage of the floral development. Alogmaiathat tear the floral button in search of food. After seven days, the boxes were placed autogaamia a germinator and maintained during a period of five days, the number of normal plant seeds was computed at the end.

Autogamy The autogamy was evaluated through the sacking of 20 inflorescences and of 20 individualized floral buttons of 0. The crossed pollination was evaluated in 20 floral buttons, emasculated before the dehiscence of the anthers.

Table 1 indicates the values obtained for the analysis of the characters in each test. The plant seeds were measured in total length from hypocotyl to radiclewhich obtained the length average of 10 plants three repetitions for each test. Plant Speciation, pp.
