Intervention effect Low density gave the highest fraction of dry matter allocated to cucumber fruits.
Intervention effect Low density gave the highest soluble sugar, total phenol and flavonoid contents in cucumber fruits.
Intervention effect Low density gave the highest soluble protein, vitamin C and chlorophyll contents in cucumber fruits.
Intervention effect Low density gave the highest carotenoid contents in cucumber fruits.
