Bulletin of the National Research Centre

Table 1 Effect of Kinetin on the development of in vitro potato microtubers

Characters of microtuberization	Without kinetin	With kinetin
No. of days to begin tuberization	12 ± 0.577^a	8 ± 0.577^b
No. of days to reach 50%tuberization	30.3 ± 0.723^a	24.5 ± 0.348^b
% of tuberization after 8 weeks	74.4 ± 1.131^b	81.8 ± o.608^a
No of tubers per plantlet after 8 w	1.4 ± 0.066^a	1.5 ± 0.066^a
Weight of microtuber (mg)	50.6 ± 0.457^b	62.6 ± 0.288^a

V values are means ± SE, LSD test at level (p < 0.05)
Values with the same superscript letters (a,b,c or d) are not significantly different from each other whilst, values with different superscript letters are significantly different
