    Comparison of fertile and sterile male gametogenesis in Cryptomeria japonica D. Don

    Cryptomeria japonica D. Don is one of the most important conifers for forestry; however, the pollinosis caused by this species is the most prevalent allergy in Japan. Male-sterile mutants have attracted attention...

    Paternity analysis in a progeny test of Cryptomeria japonica revealed adverse effects of pollen contamination from outside seed orchards on morphological traits

    To evaluate the effects of pollen contamination from outside of Cryptomeria japonica seed orchard on the growth performance (height and diameter at breast height, DBH) and morphological traits (stem straightness ...

    Cytological study of a male-sterile Cryptomeria japonica that does not release microspores from tetrads

    To determine the mechanism of male-sterility Cryptomeria japonica tree Shindai3, the process of microspore development was observed under light and fluorescence microscopy. Microspore development in the Shindai3 ...

    Gene flow and mating system in five Cryptomeria japonica D. Don seed orchards as revealed by analysis of microsatellite markers

    We investigated gene flow in five Cryptomeria japonica D. Don seed orchards of two different types (common and miniature) at widely spaced locations using microsatellite markers. The quality of a seed crop is det...

    Plus tree of Cryptomeria japonica D. Don with a heterozygous male-sterility gene

    To find plus tree clones of Cryptomeria japonica that are heterozygous for a male-sterility gene (Aa), we crossed a homozygous male-sterile tree (aa) with 63 clones. Male sterility in this case is controlled by a...

    Stand structure and composition of a 60-year-old larch (Larix kaempferi) plantation with retained hardwoods

    Tree retention is understood as a key practice in creating complexity, leading to heterogeneity in resources and habitats in managed stands. In this article, we clarify the long-term effects of tree retention ...

    Study of sugi (Cryptomeria japonica D. Don) with male-sterility gene using CAPS markers

    The frequency of open-pollinated male-sterile seedlings from a male-sterile mother tree in Cryptomeria japonica D. Don was determined in 765 open-pollinated seedlings. Pollen was not formed by 29 out of the 765 s...

    Effects of stand density on the productivity ofCryptomeria japonica male flowers

    We have studied male flower production and relative illumination in clonal sugi (Cryptomeria japonica) forests planted at densities of 1,500/ha, 3,000/ha, and 5,000/ha, to clarify the effects of forest management...

    Inheritance of the trait of male sterility inCryptomeria japonica

    Matings of male-sterileC. japonica and fertile eliteC. japonica, as well as backcross seedlings of male-sterile trees, were carried out to clarify the genetic trait of male sterility of theC. japonica. The seeds ...

    Cytological and genetical studies on male sterility inCryptomeria japonica D. Don

    Genetic male sterility is a useful trait in plant breeding, especially in angiosperm crops such as corn, onion and carrot. We found a male sterile sugi (Cryptomeria japonica D. Don) tree in Toyama, Japan. Pollen ...
