Objective: to evaluate the physiological quality of 11 soybean (Glycine max L.) varieties stored under natural conditions in the state of Yucatán, Mexico.
Design/Methodology/Approach: seeds of 11 soybean varieties were stored for 11 months in sealed polythene bags. At the start of storage, the seeds were evaluated for germination, electrical conductivity, and 100 seeds were weighed. From months 3 to 11, the germination and electrical conductivity of each sample were assessed monthly. The initial and final weights of 100 seeds were obtained. The data obtained were analyzed in a completely randomized scheme with factorial arrangement.
Results: differences were observed (p?0.05) in storage tolerance between the varieties, however, the loss of physiological quality was noticeable beginning at the third month of storage. The Tamesi and H-100 varieties showed the seed’s greatest loss in germination and weight, and the highest value of electrical conductivity.
Limitations/Implications: soybeans are produced in the Yucatán Peninsula, but limitations to conserving the seeds are high temperatures and relative humidity which can be common in the state.
Conclusions: soybeans exhibit problems in maintaining their physiological quality in storage under natural conditions, and these problems are also reflected in the loss of seed weight.
