Effect of soybean seed priming on germination and vigour depending on the seed lot and sowing date

Abstract

The objective of this paper was to examine the effect of seed lot, sowing date, and priming on germination and vigour of soybean seed. Three different seed lots of an old soybean variety (Lot 1, Lot 2, Lot 3) created at the Institute of Field and Vegetable Crops in Novi Sad were used. There were three sowing dates: 10 April, 20 May and 20 June. KNO3 (1%), H2O2 (0.1%), GA3 (0.075%) and distilled water were used as primers. The results showed that soaking the seed prior to sowing, so called priming, positively affected seed germination and vigour in all three lots and with all three sowing dates. The best effect was accomplished with Lot 1 and sowing on the third date. With regards to primers, the best effect was achieved with the application of KNO3 and H2O2 solutions. Research has shown that even soaking the seed in distilled water, which is a simple, cheap, and ecological method of priming, in most cases leads to improvement of germination and vigour of soybean seed.

Cilj ovog rada bilo je ispitivanje uticaja partije, rokova setve i rastvora za potapanje na klijavost i životnu sposobnost semena soje. Kao materijal poslužile su tri partije semena soje (partija 1, partija 2, partija 3) stvorene u Institutu za ratarstvo i povrtarstvo u Novom Sadu. Setva je izvršena u tri roka: 10. aprila, 20. maja i 20. juna. Kao rastvori za potapanje korišćeni su KNO3 (1%), H2O2 (0,1%), GA3 (0,075%) i destilovana voda. Rezultati su pokazali da je potapanje semena pre setve (prajmiranje) imalo povoljan uticaj na klijavost i životnu sposobnost semena kod sve tri partije, ali i kod sva tri roka setve. Najbolji efekat ostvaren je kod partije 1 i setvom u trećem roku. Primenom rastvora kalijum-nitrata, odnosno vodonikperoksida postignut je najbolji efekat. Istraživanja su pokazala da čak i potapanje semena u destilovanu vodu, što predstavlja jednostavan, jeftin i ekološki metod, u većini slučajeva dovodi do poboljšanja klijavosti i životne sposobnosti semena soje.
