The term underground stem is not used correctly as mesocotyle that is the first internode of barley, wheat and rye. Mesocotyle does not elongate and it remain in the seed in case of these crops. The elongated stem is second internode of these crops and not mesocotyle but rhizome or underground stem. The node on which the underground stem is attached is coleoptile node and coleptile is attached here. The objective of this study was to determine if the depth of sowing affect the coleoptile length and plant height. The deeper sowing caused the longer coleoptile length and plant height. Coleoptile length and plant height of 2cm depth of sowing showed significant difference with 6cm and 10cm depth of sowing in barley and wheat. Variation of these two characters were high in rye and corn because these crops were both heterogeneous due to out crossing. All the varieties of 4 crops showed significant correlation between coleoptile length and plant height. Chilbohomil showed highly significant correlation between two characters.
