Eighteen seedless grape genotypes differing in ripening season (early, mid and late) and in seed trace size (small, medium and large) were harvested at 6, 10, 14, 18 and 22 weeks past bloom (wpb). Using embryo rescue techniques it was studied if embryo do abort as the fruit matures and what percent embryos remain viable at later stages. The size of seed trace was also investigated to determine its influence on embryo viability during maturation. It was found that genotype have great influence on embryo culture traits. Late maturing genotypes showed fewer rescued embryos, germinated embryos and transplantable plants than early and mid season ones. The best culture time for grape embryo rescue is 6 and 10 wpb. At these dates, the largest number of embryos,... |

Abstract Considering there is no illustrated scale of the principle anomalies observed for banana seeds, the objective of this guide is to cover in detail, for the first time, the categories to classify the most common types of anomalies observed in banana embryos and seeds, as well as in vitro embryo rescue and culture, taking into account the experience acquired by the banana breeding program at Embrapa in Brazil. Four classes to classify the seeds were proposed and with regards to classifying the embryos, eight classes were established. |
