Аннотация: ?evelopment of the gametophytes of Podocarpus nivalis up to fertilization has been described in a recent paper (Boyle and Doyle, 1953) and comparison made with corresponding phases in other podocarps. This paper follows the embryogeny, including polyembryony, up to the organization of the multicellular clumps destined to form the embryo proper. Comparison is also made with other eupodocarps.

Аннотация: In this ivestigation, the chromosome number in the embryos of polyembryonal Picea abies seeds was determined. Polyembryony in seeds of Narway spruce is of rather common occurrence in the northern regions of Scandinavia. The selection of such seeds for experimental purposes can be easily made with the help of x-ray radiography.Among 220 polyembryonal seeds investigated there was one with two embryos. One of the embryos was normal (2n=24), the other was a mosaic aneuploid with chromosome number ranging from 12 to 24. Some other cytological abnormalities were also observed in this embryo.

Аннотация: In this investigation the effect of the germination periods of 14, 21 and 30 days was studied on the percentage and the rate of germination of Pinus silvestris and Picea abies seed. Samples from areas lying between 50 degrees N and 68 degrees N latitudes were used. Seed with well-developed embryo and endosperm and with high viability, as well as that with reduced viability due to age or due to poor embryo and/or endosperm development was tested. The results showed that in former type of seed, a germination period of 14 days may be adequate. However, in the later type of seed, a longer period (21 or 30 days) may be desirable, so that a sample can attain its maximum germination percentage

Аннотация: The purpose of the present investigation was to compare the megasporogenesis in a clone of Norway spruce with an ordinary seed set and a clone of a reduced seed set. The early prophase I stages had the same appearance in both clones. During the last part of diplotene there was a separation of the bivalents (i.e. desynapsis occurred) in the clone with the reduced seed set. During metaphase I - anaphase I 97 per cent of the embryo sac mother cells from the desynaptic clone cantained at least one univalent. As a consequence of the occurrence of univalent micronuclei and other irregularities were observed during subsequent stages. Frequently the irregularities caused a degeneration of the cells. Thus, it was proved that the desynapsis was resposble for the poor seed set in the desynaptic clone of Norway spruce.
