- Observation Across rice root types I to III, roots became thinner and paler in colour.
- Association From root type I to III, rice shoots showed poorer growth in height and weight.
- Association Thinner root types of rice had heavier ears relative to culms.
- Association Rice varieties with thicker roots showed leaf tip burn earlier than those with thinner roots.
- Association Rice varieties with thicker roots showed lower promotion of premature heading in nursery.
- Mechanism The authors interpret the root types as indicating different abilities of physiological function.
- Observation Most rice varieties cultivated in the temperate zone of Asia belonged to root type II and III.
- Association Among rice varieties, the more resistant to soil reduction, the larger the root diameter.
- Association More resistant rice varieties produced larger numbers of roots, even in solutions made reductive by adding hydroquinons.
- Association More resistant rice varieties produced longer roots, even in solutions made reductive by adding hydroquinons.
