Strąki bobu odmiany Windsor Biały przechowywano w temperaturze 1-2°C i wilgotności 85-90%. Obserwacje i analizy prowadzono w odstępach 3-dobowych, a eksperyment zakończono po 18 dobach, gdy liczba nasion z objawami starzenia przekroczyła 10%. Wraz z upływem okresu przechowywania obserwowano systematyczny ubytek masy strąków, masy 1000 szt. nasion przy zbliżonym udziale masy nasion w masie strąków. Analizy fizykochemiczne nasion wykazały wzrost zawartości suchej masy, skrobi, białka surowego, niewielkie wahania w ilości cukrów oraz powolny spadek poziomu witaminy C.

Broad bean „Windsor Biały" cultivar was used in the investigation at the stage of 30% dry weight content in seeds. Broad bean pods were stored at temperature of 1-2°C and air humidity of 85-90%. Observations and analyzes were carried out at 3-day intervals and the experiment was ended when in the given population the number of seeds with the symptoms of secoscence exceeded 10% (i.e. after 18 days). With the prolonged period of storage the firmness of pods gradually decreased and after 18 {.lays Iheir initial weight was reduced by 11%. Afler that period the share of marketable seeds in the total weight or pods increased from 43,9% directly after harvest lo 44.4%. Al the same time the weight of 1000 seeds decreased from 4221 to 3801 g. During storage a great part of seeds preserved their natural colour, though with the passage of time the percentage of seeds with symptoms of ageing rose; it amounted lo 0.6 directly after harvest and to 1.4%, 1.9%, 3.0%, 4.7%, 7.0%, and 11,0% after 3, 6, 9. 12, 15, and 18 days, respectively. Changes in the physicochemical compositions of (he seeds concerned all components analyzed. A distinct gradual increase occurred in dry weight content from 29,97%j directly after harvest to 34,40% after 18 days of storage, in starch content from 11,37 lo 12,35%, and in protein content (total N x 6.25) from 8.72 to 9.89%. The content of total sugars varied about 3.0% while the content of vitamin C decreased from 21.6 to 16.0 mg/100 g of fresh weight.
