Inthe vegetative phase of growth in bean (Phaseolus vulgaris L.), the dry matter gain depends on the physiological behavior and growth habit of the bean plant. The Growth process in relation to growth type were evaluated in the present study. The purpose of the study was to establish growth type and growth index relations in ICA-Cerinza (growth type 1) and ICA -Tundama (growth type 11) wich are both bush bean varieties. The plants were sown in 40.5 m2 plots, in rows spaced 0.5 m. and 0.12 m. between plants in a randomized completely block design with 4 replications; samples of 3 plants per plotwere taken 7 days each starting 15 to 78 days after emergence. Total dryweight (TOW) Stem dryweight (SOW), leaf dry weight (LOW) and total leaf area (TLA) were determined. Relative growth rate (RGR), net assimilation rate (NAR), leaf area ratio (LAR), leaf weight ratio (LWR), and specific leaf area (SLA), were determined by the classical aproach. Significant differences in TDW, SDW, LDW, and TLA between varieties were detected in the 15 and 78 days evaluations. Similar results were obtained for RGR, NAR, LAR, LWR, and SLA. The mean RGR was 0.0455 g. g-1 .day-1 in Cerinza and 0.0437 g.g-1.day -1 in Tundama but these were no statistically different. NAR and RGR had similar trends and were positive and significantly correlated. LAR decreced linearly in Cerinza, but it was cuadratic in Tundama with the highest values in the initial and the last evaluations. The LWR show that Tundama variety translocated more dry matter to assimilatory tissue formation. SLA was similar for the two varieties, but it was higher in the indeterminate (type 11), showing that Tundama had moretinny leaves. Growth analysis utilizing fixed time periods did not allow to detect differences between varieties. Apparently, these were similar in physiological behavior during the vegetative phase independently of growth type.
