This analysis was performed while considering the cultivars and environmental conditions (CO2 concentration and humidity control). Our results showed that increase in the number of stems during cultivation had no effect on the light use efficiency or amount of cumulative intercepted light. Furthermore, it was observed that increased stem density resulted in higher dry matter distribution ratio of fruits along with increased yield in the form of a greater number of flowers and fruits per area. However, this effect on the yield differed between the cultivars and environmental conditions. It is concluded from these results that increasing the stem density is more effective in enhancing yield, when using a cultivar whose fruit size does not change with the source strength, such as ‘Rinka409’. Main stems were observed to use the photosynthetic products prior to the side branches, which caused delayed growth of the latter under insufficient availability of light for photosynthesis; in such cases, the contribution of increased stem density to yield increase may be low. Therefore, it is important to determine the most suitable timing to start the elongation of side branches and the proportion of the plant biomass that extends into these branches; this should be done while considering solar radiation and environmental control conditions, such as CO2 application.","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24514/00000244","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国立研究開発法人
