Projekat: Ispitivanje mogućnosti korišćenja kontaminiranih voda za gajenje alternativnih, zdravstveno bezbednih žita (MPNTR - 31006)
Sažetak
Cilj istraživanja bio je da se dokaže koliko veličina semena i temperaturni režimi pri ispitivanju kvaliteta semena utiču na energiju klijanja i ukupnu klijavost kvinoje. Ispitivana je energija klijanja i ukupna klijavost sorta kvinoje KVL-37. Nakon žetve seme je osušeno i dorađeno a potom je odvojen uzorak za ispitivanje kvaliteta semena. Uzorak je podeljen na dva dela od kojih je jedan deo pomoću sita podeljen na dve frakcije veličine 1,2 mm i 0,8 mm. Drugi deo uzorka nije frakcionisan već je poslužio kao standard. Naklijavanje je obavljeno u laboratoriji na filter papiru u petri posudama na tri varijante temperaturnih režima: T1=5/15°C po 12 sati naizmenično, T2=10/20°C po 12 sati naizmenično i T3=20°C konstantno. Najveću energiju klijanja i ukupnu klijavost semena imala je najkrupnija frakcija semena od 1.2 mm. Seme sitnije frakcije 0.8 mm imalo je najmanju energiju klijanja i ukupnu klijavost. Primenom temperaturnog režima T2 u kome se temperature od 10°C i 20°C po 12 sati naizmenično smenjuju, dobijene su značajno veće vrednosti energije klijanja i ukupne klijavosti semena kvinoje u odnosu na temperaturne režime T1 (5/15°C po 12 sati naizmenično) i T3 (20°C konstantno).
Abstract
The aim of the study was to demonstrate how seed size and temperature regimes on seed quality affect the germination rate and total germination of quinoa. The energy and total germination quinoa variety KVL-37 have been investigated. Following the harvest, the seeds were dried and processed, and then the sample of seeds was separated for testing the quality. The sample was divided into two parts; one part is divided into two fractions of size 1.2 mm and 0.8 mm, while the second part of the seeds sample is fractionated and it served as a standard. Germination was carried out in the laboratory on the filter paper in Petri dishes. Three variations of temperature regimes were tested: T1 = 5/15 °C altering on each 12 hours, T2 = 10/20 °C altering on each 12 hours, and T3 = 20°C constantly. Results showed that the highest seed germination energy and total germination had seed fraction of 1.2 mm size. Smaller seeds of 0.8 mm size had the lowest seed germination energy and total germination. Application of temperature regime T2, with altering temperatures (10 °C and 20 °C on every 12 hours), possessed significantly higher values for seed germination energy and total germinationin comparison to T1 temperature regimes (5/15 °C altering on each 12 h) and T3 (constant 20°C).
