Carbon use strategies in shoot and acorn growth of two evergreen broadleaf trees unraveled by seasonal carbohydrate measurements and carbon isotope analysis

Autor: Qingmin Han, Daisuke Kabeya, Yoshiyuki Inagaki, Tatsuro Kawasaki, Akiko Satake

Publikováno v: Tree Physiology.

Woody species have evolved carbon (C) storage processes that meet needs for reserves associated with asynchronies between C supply and demand. However, our understanding of storage dynamics is still elusive in mature trees, especially when reproducti

As climate change progresses, it is becoming more crucial to understand how timber species respond to increased drought frequency and severity. Photosynthetic traits in a 40-year-old clonal Japanese cedar (Cryptomeria japonica) plantation were assess

Effect of stem radial growth on seasonal and spatial variations in stem CO2 efflux of Chamaecyparis obtusa

Autor: Tatsuro Kawasaki, Koichiro Gyokusen, Hajime Utsugi, Yukihiro Chiba, Qingmin Han, Takuya Kajimoto, Masatake G. Araki

Publikováno v: Trees. 29:499-514

Besides stem temperature, seasonality and vertical gradient in stem diameter growth strongly affect both seasonal and vertical variations in stem CO 2 efflux. Stem CO2 efflux (E s) is known to vary seasonally and vertically along tree stems. We measu

Thinning alters crown dynamics and biomass increment within aboveground tissues in young stands of Chamaecyparis obtusa

Autor: Tatsuro Kawasaki, Masatake G. Araki, Yukihiro Chiba, Qingmin Han, Daisuke Kabeya, Chiharu Migita, Satoshi Saito

Publikováno v: Journal of Forest Research. 19:184-193

The stand density of a forest affects the vertical distribution of foliage. Understanding the dynamics of this response is important for the study of crown structure and function, carbon-budget estimation, and forest management. We investigated the e

Fine-root dynamics in a young hinoki cypress (Chamaecyparis obtusa) stand for 3 years following thinning

Autor: Qingmin Han, Masatake G. Araki, Yukihiro Chiba, Masamichi Takahashi, Shinji Kaneko, Tatsuro Kawasaki, Kyotaro Noguchi

Publikováno v: Journal of Forest Research. 16:284-291

Fine roots play a key role in carbon and nutrient dynamics in forested ecosystems. Fine-root dynamics can be significantly affected by forest management practices such as thinning, but research on this topic is limited. This study examined dynamics o

Estimation of whole-stem respiration, incorporating vertical and seasonal variations in stem CO2efflux rate, ofChamaecyparis obtusatrees

Autor: Qingmin Han, Yukihiro Chiba, Tatsuro Kawasaki, Masatake G. Araki, Takuya Kajimoto, Hajime Utsugi

Publikováno v: Journal of Forest Research. 15:115-122

We examined vertical and seasonal variations in stem respiration rates in a 50-year-old plantation of Japanese cypress, Chamaecyparis obtusa (Sieb. et Zucc.) Endl., in central Japan, and discuss a practical and precise method to scale a point-measure

Leaf-age effects on seasonal variability in photosynthetic parameters and its relationships with leaf mass per area and leaf nitrogen concentration within a Pinus densiflora crown

Autor: Tatsuro Kawasaki, Takashi Nakano, Qingmin Han, Yukihiro Chiba

Publikováno v: Tree Physiology. 28:551-558

In the temperate zone of Japan, Pinus densiflora Sieb. et Zucc. bears needles of up to three age classes in the upper crown and up to five age classes in the lower crown. To elucidate the effects of leaf age on photosynthetic parameters and its relat

Publikováno v: Ecological Research. 23:965-972

Inter-annual variations in leaf-fall phenology and leaf-litter nitrogen concentration were investigated for 13 years in a coniferous plantation of hinoki cypress trees (Chamaecyparis obtusa Endlicher) in Kochi, southern Japan. Mean annual nitrogen co
