AB  - 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 oC (for 10, 30, 60 and 90 minutes), 80 oC (for 10, 30, 60 and 90 minutes) and 90 oC (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.
AB  - U semenu lucerke se, osim normalnog semena, javlja i seme sa tvrdom semenjačom koja onemogućava prodiranje vode i gasova u unutrašnjost i tako sprečava klijanje. Zbog toga, tvrda semena ne klijaju, iako su u idealnim laboratorijskim uslovima ili u polju. Dešava se i da klijaju naknadno, kada su klijanci iz normalnih semena razvijeni, ali kao takvi nemaju značaja za zasnivanje useva. Smanjenje  broja  tvrdih  semena  i  povećanje  klijavosti  može  se  postići  skarifikacijom  semena  kiselinama,  fizičkim  oštećenjem semenjače,  toplom  vodom,  hlađenjem  i  dr. Skarifikacija  primenom  temperaturnih  tretmana  pred setvu  je  jednostavna,  jeftina  i bezbedna za čoveka i okolinu. Ispitivanja su sprovedena na tri sorte lucerke: Medijana, Banat, Zaječarska 83. Seme sve tri sorte je izl   agano  10,  30,  60  i  90  minuta  na  temperaturama  od  70,  80  i  90oC.    Nakon  tretmana  u  laboratorijskim  uslovima  ispitivana  je  klijavost  i  tvrda-dormantna semena.  Dobijeni rezultati ukazuju da se temperaturnim tretmanima semena može značajno (p≥0.05) uticati  napovećanje  klijavosti.    Utvrđena  je  značajna  interakcija  sorta  x  temperaturni  tretman,  što  ukazuje  da  je  optimalni temperaturni tretman bio različit za različite sorte.
