“…High temperatures (about 80 °C) can be effective in reducing harddormant alfalfa seed in relation to lower temperatures. However, negative effects were observed when the temperature was 80 °C or 90 °C, as well as with longer exposure times (Rincker, 1954;Rutar et al, 2001).…”

In addition to normal seeds, hard seeds of alfalfa have often been found after harvest. Such seeds prevent the penetration of water and gases into the seed interior, causing the reduction in germination. They do not tend to germinate even under ideal laboratory or field conditions, or they exhibit late germination. Consequently, they are of no relevance to planting crops. A decrease in the amount of hard seeds and an increase in germination can be achieved by scarification of acids, physical damage to the seed coat, hot water, cooling, etc. Temperature treatment scarification prior to sowing is a simple and inexpensive solution, safe for humans and the environment. The tests were carried out on three alfalfa cultivars: 'Medijana', 'Banat' and 'Zaječarska 83'. Their seeds were exposed to temperatures of 70 o C (for 10, 30, 60 and 90 minutes), 80 o C (for 10, 30, 60 and 90 minutes) and 90 o C (for 10, 30, 60 and 90 minutes). After the treatment under laboratory conditions, the germination rate and the share of hard/dormant seeds were investigated. The results obtained indicate that the increase in germination can be significant (p ≥ 0.05) provided temperature seed treatments are applied. Furthermore, the optimal temperature treatment was found to be essentially dependent on the specific alfalfa cultivar.

“…l\Iartin ( 1945) reported that impermeable seeds of sweet clover, in natural field seedlings and when stored over-winter in unheated buildings in Iowa, became 80-lOOo/a permeable by the middle of the following April. Hutton and Porter ( 1937), Lute (1928), Rincker (1954), Staker (1925) and Stewart ( 1926) found that subjecting seeds of impermeable species to dry heat temperature of 60°-85 oC for periods of 2-6 hr effectively decreased the percentage of impermeable seeds. Stone and Juhren (1951) found that the fire induced germination of Rhus ovata.…”
