Rainfalles recorded in summer of 2005 during ripening of wheat (SMH Craiova,2005)The primary observation into laboratory show that among five varieties ofwinter wheat analyzed, two varieties shows that are genetically non-dormand(Crina and Dor) and three varieties present genetically characteristics as dormandvarieties (Glosa, Boema and Dropia). From sample’s analyzed, the Crina varietypresent 7.00 % of seeds sprouted into spikes. The Boema and Dropia varietiesshow a resistence to spike’s sprouting in climatic condition of summer 2005 inCraiova area (Table 1), but into the field have been founded some plants whichpresent strong phenomenon of sprouting into spikes (Figure 3).After the analyses of germination after 48 h, 72 h and 96 h, into laboratorycould be seen that the highest germination have been obtained by Dropia varietywith 92 % of normal germs after 96 h, followed by Boema variety with 90% ofnormal germs developed after 96 h. The smallest germination have been obtainedby Dor variety with 83% of normal germs developed after 96 h. Could be seen alsothat after 48 h, Dor variety have developed more sprouts than Glosa variety, but atthe end of germination time, Dor variety have developed 83 normal germscomparative with Glosa variety which developed 85 normal germs.From sample’s analyzed, the Crina variety present 7.00 % of seedssprouted into spikes, but after 48 h of germination developed 27 sprouts, more thanGlosa variety which have developed 18 sprouts and presented 2,75% of sprouting89
