Aspects of soyabean root structure and plant development in compacted soils


, : Aspects of soyabean root structure and plant development in compacted soils. Pesquisa Agropecuaria Brasileira 35(5): 929-938

In a pot trial, soyabeans IAC-8 and IAC-14 were grown on a clayey soil with compaction levels of 0.95 (control), 1.20, 1.35 or 1.50 kg/litre. Soil compaction did not affect the anatomical structure of the roots. In IAC-8, leaf number, plant height and the dry matter of roots and stem decreased with increasing soil compaction, while root length increased.

In 5 dogs, each with a gastric fistula, parietal cell vagotomy reduced gastric acid output after pentagastrin by intravenous infusion; truncal vagotomy had a similar but less pronounced effect. Acid responses were reduced equally by both types of...
