Garvey-Kelson mass relations connect nuclear masses of neighboring nuclei within high accuracy, and provide us with convenient tools in predicting unknown masses by extrapolations from existent experimental data. In this paper we investigate optimal"channels" of the Garvey-Kelson relations in extrapolation to the unknown regions, and tabulate our predicted masses by using these optimized channels of the Garvey-Kelson relations.

A description of a successful direct somatic embryogenesis induction from immature zygotic embryos of a camphor tree （Cinnamomum camphora L.） is presented. After a subculture of 2-3 years, embryogenic calli could be derived from primary somatic embryos. Immature zygotic embryos were cultured on a Murashige and Skoog （MS） basal medium supplemented with a range of combinations of cytokinins （BA） and auxins （2,4-D or NAA） for somatic embryo induction. Primary somatic embryos could be induced directly in almost all PGR combinations. A positive effect of 2,4-D on somatic embryogenesis from immature zygotic embryos of camphor tree was obtained. BA at appropriate concentrations （〈 5 mg-L-1） had an effect similar to 2,4-D, whereas high concentrations （〉 5 mg·L^-1） of BA had the effect of restraining somatic embryo induction. NAA had a less positive effect on somatic embryogenesis than 2,4-D.

This study addressed the differences in microsporogenesis between male sterile and fertile lines of Chinese pink. The microsporogenesis processes of male sterile and fertile lines were histologically examined in squashed pollen grains and in paraffin embedded sections. A stable male-sterile line （H-37B） was obtained following six generations of inbreeding in a self-fertile line, followed by two generations of backcrossing. In the corresponding fertile line, development of the mature pollen grains was followed through the initiation of the sporogenous cell, microsporocyte formation, and the tetrad developmental period. In the male-sterile line, abortion of the developing pollen grains was observed to take place at various stages, namely, sporogenous cell growth, mother cell meiosis, and tetrad transformation to the uninuclear state. The pollen grains of the fertile line were spheroid, turgid, and viable. By contrast, the male-sterile line produced pollen that was irregular in shape, empty, and nonviable. The abortion of the microspore in the male-sterile line appeared to relate to abnormal growth of the tapetum layer.
