Potapanje semena – metod za povećanje klijavosti semena soje

Abstract

Cilj rada bio je da se ispita da li potapanje semena može da poboljša klijavost semena soje u nepovoljnim uslovima, odnosno na nižoj temperaturi. Za istraživanje je korišćeno seme sorte soje NS Apolo, koja je selekcionisana na Institutu za ratarstvo i povrtarstvo u Novom Sadu. Seme je potapano u različite rastvore: kalijum nitrat - KNO3 (1%), askorbinska kiselina - AsA (100 mg l-1) i kalijum hlorid - KCl (1%). Nakon sušenja, seme je naklijavano na temperaturi 10°C, dok je seme naklijavano na optimalnoj temperaturi od 25°C poslužilo kao kontrola. Rezultati istraživanja su pokazali da je potapanje semena pre setve poboljšalo energiju klijanja, klijavost semena i brzinu klijanja u uslovima niske temperature. Upotreba rastvora KNO3 i AsA bila je efekasnija od primene rastvora KCl u uslovima niže temperature. Rastvor KNO3 i AsA su značajnije uticali na povećanje klijavosti i energije klijanja.

The aim of this study was to examine whether priming seeds can improve the germination of soybean seeds in unfavorable conditions, i.e. at a lower temperature. For the research, the seeds of the NS Apolo soybean variety, which were selected at the Institute of Agriculture and Vegetables in Novi Sad, were used. The seeds were primed in different solutions: potassium nitrate - KNO3 (1%), ascorbic acid - AsA (100 mg l- 1) and potassium chloride - KCl (1%). After drying, the seeds were germinated at a temperature of 10°C, while the seeds germinated at an optimal temperature of 25°C served as a control. The research results showed that priming the seeds before sowing improved germination energy, seed germination and germination rate under low temperature conditions. The use of KNO3 and AsA solution was more effective than the use of KCl solution under lower temperature conditions. The solution of KNO3 and AsA significantly influenced the increase in germination and germination energy.
