Influence of temperature on the germination of Seeds : 6. Maize(Zea Mays L.)

[摘要] 1. The increase of the depth of sowing showed the decrease of the ratio of emergence to the amount of seeds sown and the degree of the decreasing was larger in barley than wheat. 2. The deep sowing mede the periods of the emergence of the leaves later. 3. The deep sowing made the length of the leaves and leaf sheaths longer, but these results owed to elongtion of the subcrown internodes, the actual lengths of the leaves being reduced. 4. The deep sowing gave remarkable restraint against tillering at lower nodes. 5. In case of the deep sowing over 5cm, it was found that the subcrown internode developed and the crown came up to the depth of 2-6cm.
