MODELLING ABOVE-GROUND DRY MATTER AND AREA DISTRIBUTIONS OF GREEN BEANS (PHASEOLUS VULGARIS L.) FOR PROCESSING UNDER MEDITERRANEAN CONDITIONS

In a two-pot experiment of Phaseolus vulgaris L., the influence of K and Mg gradated doses upon K, Mg and Ca content in the pods, stem and leaves was studied. The content of cations changed significantly in individual parts of the plant. The highest content of potassium was found within the dry matter of the pods (it exceeded 4%) and stalk (3–4%). The highest content of calcium (3–4%) and magnesium (0.4–0.8%) was found within the dry matter of the leaves. The effects of K gradated doses were revealed significantly in its higher content increase mainly in the leaves (by as much as 83%) and the decrease of calcium content (31%) and magnesium content (37%) was observed in the leaves and less in the stalks. The effects of Mg gradated doses were revealed in the non-significant increase in its content in the leaves and stalks and the decrease of the potassium content in the leaves (by 19%) and in stalks (11%) and even in the decrease of the calcium content (52%) mainly in the pods.

Commercial Cultivars

Growth and rates of photosynthesis of two accessions and two cultivars (Great Northern 1140 and Sutter Pink) of bean (Phaseolus vulgaris L.) were compared at 10, 15, and 23 °C in a controlled environment cabinet. The leaf area, dry matter, and rate of total apparent photosynthesis of one of the accessions was significantly higher after growth for 13 days at 10 °C than that of the commercial cultivars. This advantage was not maintained at 23 °C. In another experiment, growth of the same four cultivars was compared at light/dark temperatures of 10/10, 15/12, and 23/18 °C. The two accessions established a higher leaf area and accumulated more dry matter at the cooler temperatures than the commercial cultivars, but lost this advantage at the highest temperatures. In a field trial, the accessions had a similar rapid early growth but fell behind later in the season. Ideally, a bean cultivar for the Canadian prairie should incorporate the accession’s ability for rapid growth and leaf expansion at cool temperatures with a growth rate during mid-summer comparable to that of Great Northern 1140.
