Hi everyone we are in the process of standardizing the micro-propagation protocol of culinary banana (ABB) for commercial scale production. But, unlike Grand Naine and other table varieties of banana these culinary types are showing more elongation, lanky and week growth while hardening (Picture attached). Further we also recorded low survival in field condition. In this contest i am planning to use some additional media supplements in in vitro (may be before in vitro rooting step) to improve the plant health condition there by more field survival. I am requesting the experts to suggest the media supplements to produce the good quality planting material.
