Abstract
A laboratory experiment was carried out to investigate the effect of salinity on some morphological and phys-iological parameters in four Canola (Brassica napus L.) cultivars (Talaye, Sarigol, Zarfam and Opera) under salinity stress. Plants were grown in hydroponic solution (Hoagland 1/4 strength) under greenhouse conditions and on five-leaf stage, treated with different concentrations of NaCl: 0 (control), 50, 75 and 100 mM. After 14 days of treatment, plants were harvested and the length of shoots and roots, photosynthesis, chlorophylls and carotenoids contents of leaves were measured on four studied cultivars. In general the results showed that increasing salinity reduced leaf relative water co-ntent, shoot and root lengths and leaf area. Photosynthetic rate was declined in Talaye and Sarigol, but it was elevated in Opera and Zarfam. It should be noted that the changes induced by salinity on photosynthetic pigments was not regu-lar. The results of this study showed that among the investigated cultivars, in vegetative phase, Opera and Zarfam had higher capacity and function to salt stress tolerate than other cultivars. It also seems that Sarigol may be more vuln-erable than other cultivars under salinity stress.

Abstract
Iranian black zira is an aromatic and medicinal plant from Apeaceae family. In order to investigate the effect of fertilization and tuber age on plant height, greening percentage, flowering percentage, and yield components, an experiment was conducted in field conditions in the form of 9 main plots including NPK fertilizer at three levels (control ), fertilizer 1(2.5 grams per liter), fertilizer 2 (with a concentration of 2 times and 5 grams per liter) and tuber age at two levels of three and four years (medium and three-year-old tubers ) was carried out in, fertilizer with 2 times concentration) and tuber age at two levels (three and four years old) was carried out in 1402-1403 in Kalat region of Khorasan Razavi.The results showed that tuber weight has a direct and positive effect on the percentage of germination, flowering, plant growth and yield. The highest percentage of greening (100%) and flowering (100%) was observed in large tubers and the lowest percentage of greening (51%) and flowering (16.93) was observed in medium tubers and 0 fertilizer (no fertilization).application of 20-20-20 fertilizer (NPK) and use of tubers with more age (weight) improved the growth and yield of Iranian black zira.
