Evaluation of genetic diversity using morphological markers and gas chromatography-mass spectrometry (GC/MS) analysis in some Aloe sp. accessions

摘要

Thirty three?Aloe?accessions were collected from different geographical regions of Iran. Morphological evaluation and gas chromatography-mass spectrometry (GC/MS) analysis were applied for showing genetic variations among the studied accessions. Morphological analysis indicated that all the studied characters have a significant difference of P < 0.01 among?Aloe?accessions. Cluster analysis indicated that there were differences among all accessions and commercial accessions performed better than wild accessions and were ranked higher; while the most wild-accessions performed worse than commercial accessions and were ranked lower. According to the results, 26 bioactive phytochemical compounds were identified. Furthermore, results indicated that these compounds in accordance with identified bioactive phytochemical compounds in wild?Aloe?plants by other researchers. With attention to the obtained results of GC/MS analysis, these compounds have fluctuated within selective?Aloe?accessions. Morphological analysis together with GC/MS analysis indicated that there are remarkable genetic variations among selective?Aloe?accessions.
