Biomass and morphology of fine roots of sugi (Cryptomeria japonica) after 3 years of nitrogen fertilization
Increasing nitrogen (N) deposition may affect carbon and nutrient dynamics in forest ecosystems. To better understand the effects of N deposition, we need to improve our knowledge of N effects on fine roots (roots <2 mm in diameter), as they are a key factor in carbon and nutrient dynamics. In this study, we fertilized 1 × 2 m plots in a sugi (Cryptomeria japonica) stand (336 kg ha(-) (1) y(-) ...
متن کاملModeling Diameter Growth and Self-Thinning in Planted Sugi (Cryptomeria japonica) Stands
Abstract: The objectives of this study were to analyze diameter growth in relation to natural thinning in high-density stands in even-aged, pure plantation forests and to develop a growth prediction system based on Japanese permanent plot data. Long-term data recorded in even-aged, pure, unthinned stand plots of Sugi (Cryptomeria japonica) forests were available. Relationships between log-trans...
متن کاملAllergic conjunctivitis caused by sugi (Cryptomeria japonica D. Don) pollen out of season.
Allergic conjunctivitis caused by sugi pollen is considered to be strictly a "spring disease". However, a recent report indicated that sugi pollen is scattered not only in spring but in all seasons, especially in the autumn. We retrospectively determined the number of patients with allergic conjunctivitis caused by sugi pollen during each month for 3 consecutive years, and also investigated the...
متن کاملForecasting models for sugi (Cryptomeria japonica D. Don) pollen count showing an alternate dispersal rhythm.
BACKGROUND Pollen information is indispensable for allergic individuals and clinicians. This study aimed to develop forecasting models for the total annual count of airborne pollen grains based on data monitored over the last 20 years at the Mie Chuo Medical Center, Tsu, Mie, Japan. METHODS Airborne pollen grains were collected using a Durham sampler. Total annual pollen count and pollen coun...
متن کاملA consensus linkage map for sugi (Cryptomeria japonica) from two pedigrees, based on microsatellites and expressed sequence tags.
A consensus map for sugi (Cryptomeria japonica) was constructed by integrating linkage data from two unrelated third-generation pedigrees, one derived from a full-sib cross and the other by self-pollination of F1 individuals. The progeny segregation data of the first pedigree were derived from cleaved amplified polymorphic sequences, microsatellites, restriction fragment length polymorphisms, a...
