Current Status of Research Progress
Current Status of Research Progress

1: Research has progressed more than it was originally planned.

Reason

実験は成功し、それらの成果についての論文の出版が始まっているため。さらに、今年度4月以降、以下の2編の論文が出版されているため。

(成果原著論文、いずれも2021年4月に出版)
1. Risa Iwabe, Kohei Koyama*(責任著者), Riko Komamura (2021) Shade avoidance and light foraging of a clonal woody species, Pachysandra terminalis, Plants 10(4), 809, https://doi.org/10.3390/plants10040809
2. Riko Komamura, Kohei Koyama*(責任著者), Takeo Yamauchi, Yasuo Konno, Lingshuang Gu (2021) Forests 12(4), 452, https://doi.org/10.3390/f12040452

Strategy for Future Research Activity

研究計画の実験は成功し、データの取得が完了しているため、今年度は、引き続き学術雑誌への論文掲載による成果発表を行う。

Causes of Carryover

年度末に執筆開始した論文の執筆および出版のタイミングが年度をまたいだため。
