| This study was conducted in tissue culture Lab. Al Mussaib technical college for the period from the first of march up to the third of December 2006 1/3/2006 – 3/3/2006. In order to study lemon juice and the Co conut milk in the vegetative production for Patato crops in vitro. Patato tubers desery variety under 22C° top merestemic was cut and cultured in M.S medium which contains different concentration (1, 2) ml/L for Lemon juice and concount milk with using BA as control with concentration of 2mg/L. Results and table (1,2,3) indicated that the addition of Lemon juice with 2ml/L was dominated in the other treatments statically in Length which is (5.46 cm) and numbers of nuds 3.6 nuds/Plant, wet weight 2.06 gm/plant, vegetative branches 4.2 branches/ plant, length of root 1.62 gm/plant. Mean while the treatment coconut milk yield 3.95cm, 2.93 nud/plant fresh weight 1.53 gm/plant, number of vegetative branches 3.2 branches/plant root length 2.17cm/plant, fresh weight of roots 1.31 gm/plant while the control treatment (BA) yield the lowest average for the holle studied characteristic with 2.3cm for plant high, 2.86 nud/plant, 1.19gm/plant for fresh weight and the number of vegetative branches (1.86 branches/plant), root length 1.33 cm and 0.8 gm/plant for the fresh weight of roots. The above results indicated that Lemon juice with 2ml/L concentration significantly dominate on coconut milk × BA, also coconut milk treatment dominate BA treatment for the whole characteristic. |
