Abstract

In bean (Phaseolus vulgaris L.) the embryo is all the seed except the testa. In 2007, work was conducted in order to determine the ratio of the biomass from the embryonic axis complex (CEE, hypocotyl-root axis plus the two first leaves) and cotyledons and dimensions of CEE in contrasting varieties tolerant to drought, high and low yield, and the differences between bean races of Durango and Jalisco. For separation of the EEC, 20 seeds with biomass of 200, 260 and 320 ± 5 mg were selected. Seeds of 320 mg had total biomass of CEE (BTE) greater than 260 and 200 mg seed; this was due to greater total biomass of the first two leaves (BHS) and biomass of the hypocotyl-root axis (BHR). CEE separate from seeds of 320 mg had the highest leaf area of the first two leaves (AFPH) and length of hypocotyl- root axis (LHR), compared to 260 mg seed. The percentage of CEE in the embryo showed a reverse relationship with seed biomass. The cotyledons represented 98.4% of the biomass from the embryo and the CEE the rest. The drought-tolerant cultivar showed smaller width of hypocotyl-root axis (AHR) that the cultivar susceptible to drought; the high BTE from Pt Villa was due to its high BHR, meanwhile, the high BTE of FM M38 and Anita was due to a high BHR and BHS.
