Determinations of net assimilation rate (NAR) and of leaf area per plant or per metre of dril row were made at intervals throughout the growth of field-crops of wheat, barley, potatoes, mangolds, and sugar-beet at Rothamsted. Data are presented from 15 experiments in 6 years. The experiments included comparisons of varieties of the same crop, and of sowings made on different dates. Net assimilation rate showed similar variation with time in all years, rising during the spring months from very low values in winter to a maximum at midsummer, and subsequently falling during the late summer and autumn. This time trend is attributed to seasonal change in climatic factors. |
