Fig. 1From: Overdominant expression of related genes of ion homeostasis improves K+ content advantage in hybrid tobacco leavesHeterosis and variation trend of K+ content in tobacco leaves. a shows the change trend of heterosis of K+ content of F1 hybrid during tobacco leaf growth. b shows the heterosis value of H and l hybrids at 70 days after transplanting. c and d respectively represent the change trend of K+ content of H and L hybrids and their parents after 50 ~ 90 days of transplantationBack to article page
