Title
An investigation on the effects of salinity and Osmopriming on seedling dry weight and some physiological characteristics of Safflower (Carthamus tinctorius L.) varieties
Authors
Abstract
bstract
The current study was carried out during 2013 in Zahra Rosewater Company’s research greenhouse and it was aimed to investigate effects of seed Osmopriming on some physiological features of three different Safflower varieties under saline condition. So the seeds of three safflower varieties (IL 111,Arak 2811 and Isfahan) were treated by four levels of PEG6000(0,-9,-18 and -22 bar) under four levels of salinity (0,6,12 and 18 ds/m) and the statistical experiment was factorial based on CRD. According to the obtained results, all traits were significantly affected by salinity factor. Proline content and Ion leakage were increased as salinity was raised while RWC and seedling dry weight were reduced in the same condition. Isfahan variety had the highest amount of Proline and the highest RWC and Ion leakage were belonged to IL 111 and Arak varieties respectively .Compared with other Osmpriming levels, the Proline quantity that was produced by
the second level (-9 bar) of Osmopriming was higher than rest. In general, Isfahan variety had shown the
lowest dry weight and IL-111 variety had the highest dry weight in all levels of salinity and priming treatments.
