Fig. 2From: Cotton roots are the major source of gossypol biosynthesis and accumulationThe (±)-gossypol contents in cottonseeds in normal and grafted plants. The black bars showed the gossypol contents in normal plants cottonseeds, the white bars showed the gossypol contents in grafted plant cottonseeds with scion and rootstock coming from same cultivar and the gray bars showed the gossypol contents in grafted plant cottonseeds with scion and rootstock coming from different cultivars. The former name of the graft combination was the rootstock cultivar name and the latter name was the scion cultivar name. Each sample was carried out in three biological repetitions. * indicates significant difference, P < 0.05Back to article page
