Abstract

This study aimed to determine the best time of seed collection for Artemisia sieberi and Artemisia aucheri in Saleh abad rangelands of Baft County, Kerman province. After selecting a key area, the time of seed collection started from mid-November to end of January for Artemisia aucheri and from mid-October to mid-December for Artemisia sieberi. The seeds were evaluated for germination traits including germination percentage, germination rate, root length, shoot length, and vigor index. The data were analyzed, and the Duncan test was used to compare the mean values of treatments. The results showed that the delay in the time of seed collection of Artemisia sieberi from mid November to mid December caused an increased germination percentage, germination rate, seed vigor, and seedling length as 115, 119, 222, and 49%, respectively. The seeds of Artemisia aucheri collected in the first half of December compared to the first half of November increased seed vigor index, germination percentage, germination rate, and seedling length as 588, 336, 736, and 61%, respectively. Our finding showed that the delay in the time of seed collection in both of these species improved seed germination traits and seedling growth.
