Abstract
ABSTRACT
This study was carried out in the laboratory of tissue culture at the Research Garden, Horticulture Research Institute, Agriculture Research Center, Ministry of Agriculture; the experiments were done during the period from 2016 to 2020 years. This study investigated the best commercial in vitro protocol of Caladium bicolor and conservation the micro propagated shoots and effect of salinity on banana plantlets during micro propagation. The best results of surface sterilization were achieved when used 20% Clorox for 20 min. or 0.2 mg/l mercuric chloride for 5min. Also the highest values of number of shoots, shoot length and number of leaves per shoot were found at 2.0 mg/l BA or kinetin and 0.5 mg/l NAA during multiplication stage. For conservation of Caladium with sorbitol or mannitol were achieved that, number of shoots, shoot length and number of leaves per shoot was decreased by increasing the concentration of sorbitol or mannitol. The highest number of roots and root length were obtained when shoots cultured on MS medium plus 0.2mg/l IBA during rooting stage. Peat moss + perlite media was best media for acclimatization caladium plants.
Concerning, effect of salinity on banana plantlets results showed that, considerable variances in response were obviously detected. Herein, adding of 1.0 mg/L NAA and NaCl at 500.00ppm on rooting medium was statistically the most effec
