Physiological Aspects of Growth and Development of ,trate uptake was estimated by measuring the nitrate reductase activity (NRA) on the youngest developing leaf. Nitrogen fixation (NF) was measured with the acetylene reduction assay on root systems. The highest NRA occurred at the end of flowering two weeks before the highestNF was recorded during mi

It has been shown to be important to take account of the genetics of the characters included in the study to explain the results..Application of this method to a set of F.s showed that the most important characters

The Origin and Development of a Programme to Breed Leafless Dried Peastable for existing canning and packeting markets as well as for reducing some of the EEC’s over-dependence upon imported soya..Leafless peas have their origin in the use of two naturally-occurring mutant forms one of which, with leaflets converted to tendrils, was found in Finland in 1953 and the ot

Determining Ideotypes for the ‘Leafless’ Pea Cropogical and economic yield per unit area of the ‘leafless’ phenotype decreased at low planting densities because the plants were unable to compensate fully to planting densities below 100 plants/m.. It is essential, therefore, that ‘leafless’ plants are grown at high population densities; so the idea
