چکیده
|
This study was conducted in a factorial experiment as completely randomized design with three replications in University of Kurdistan in 2014. The aim of this study was investigation of salinity stress and humic acid effects on germination indicators of savory and dragonhead, as, aromatic and medicinal plant. The treatments were humic acid (0, 0.5 and 1%) and salinity (0, 2 and 4 dS/m). The results showed that the maximum length of radicle and plumule and the highest amount of radicle and plumule dry and fresh weight was produced in 1% humic acid. The lowest values of mentioned traits, germination percentage and germination speed were created in 6 dS/m salinity level. Generally the most favorable interaction treatment was the third level of salinity combined with the highest level of humic acid in both plants. Furthermore, humic acid application can be improved germination and plant growth under salinity condition.
