摘要:

The pollen size variations seen among the cultivars of Ananas comosus (Bromeliaceae) and the differences seen in wall reticulations of A. comosus and A. bracteatus are recorded. Among the different cultivars the pollen viability was between 24–92% according to the peroxidase and acetocarmine tests. With selfing, the pollen tubes grew to a maximum of about 13% of the stylar length in about eight hours after pollination. Results obtained, in two different media, regarding in vitro percentage germination and tube length are compared. The additions of various hormones and vitamins improved pollen tube growth but not germination. The reciprocal cross between cultivars resulted in seed formation, and the highest number of seeds was obtained with MasmerahxMauritius crosses. The results of the present study are compared with relevant literature
