Última A new case of late-acting self-incompatibility in Capparis L. (Brassicaceae): C. jacobinae Moric. ex Eichler, an endemic andromonoecious species of the Caatinga, Pernambuco State, Brazil Acta Botanica Primo,Luis Miguel; Machado,Isabel Cristina. We studied the reproductive system of Capparis jacobinae Moric ex Eichler (Brassicaceae), based on controlled hand-pollination and observation of pollen tube growth made in a fluorescence microscope. Of 105 self-pollinated flowers only one produced fruits (success = 0.95%), all the other flowers abscised at the same time, between the eighth and tenth day after anthesis. Nevertheless, self- and cross-pollinated pollen tubes reached the micropyle. The rate of penetrated ovules in self-pollinated flowers was lower during the first 24 h after pollination; thereafter this rate was similar between self- and cross-pollinated flowers for treatments of 48 h, 72 h and 96 h after pollination. In addition, we carried out two indirect estimates of the reproductive...

Amorim,Juliane dos Santos; Souza,Margarete Magalhães; Viana,Américo José Carvalho; Freitas,Jôsie Cloviane de Oliveira. This study aimed to characterize the reproductive system of Passiflora capsularis L. and P. rubra L. In vivo controlled pollinations, in vitro pollen germination and pollen-ovule (P:O) ratio evaluation were conducted. In self-pollination, intraspecific and interspecific pollination, P. capsularis showed means of 62.5, 68.7 and 48.4% of fertilized flowers, while in P. rubra, the averages were 67.2, 62.5 and 46.9%, respectively. For in vitro germination, 52.2% of P. capsularis pollen grains germinated while in P. rubra, the percentage was 64.4. The P:O ratio was 22.4 for P. capsularis, and 27.4 for P. rubra, which included them in the category of obligatory autogamous. Passiflora capsularis and P. rubra can reproduce both by self-pollination and...
