Figure 7(a). Effects of 2-benzthiazoIyloxyacetic acid iBTOA) on growth of carrot root explants. 

 A = Basal medium — casein hydrolysate (0-05 per cent) 

 B = Basal medium-^ casein hydrolysate^ coco-nut milk (10 per cent) 

 C = Basal medium^ casein hydrolysate + BTO A at \0-0 p. p.m. 

 D = Basal medium- casein hydrolysate^ BTO A at 2-{) p.p.m. 

 E = Basal medlum^casein hydrolysate +BTO A at 0-4 p.p.m. 



Figure 7{b). Effects of 2-benzthiazolyloxyacetic acid [BTOA) on growth of explants from Jerusalem 



artichoke tuber. 

 A = Basal medium + casein hydrolysate (0-05 per cent). 

 B = Basal medium + casein hydrolysate + coco-nut milk {\0 per cent). 

 C = Basal 7?iedium + casein hydrolysate + BTOA at \0-0 p.p.m. 

 D = Basal medium + casein hydrolysate-^ BTOA at 2-0 p.p.m. 

 E = Basal medium + casein hydrolysate + BTOA at 0-4: p.p.m.
