Abstract
The seed morphology of 38 samples representing O. cumana populations from Republic of Moldova were examined to explore patterns of variation among the accessions. Features of seeds were assessed employing light microscopy and analyzed statistically. The morphological differences in length/width ratio and seed shape in local broomrape populations have been established. The size of seeds ranged from 0.36 ~ 0.42 mm in length, and 0.14~0.18 mm in width. Seeds were generally small, ovoid to elongated in shape. Using one-way test (ANOVA), cluster and principal coordinate analysis, two groups were established by seed characteristics.
Acknowledgments
The authors express their gratitude to The Technical State University of Moldova, to the National Center for Material Study and Testing, principally to dr Monaico Eugen for his support and technical assistance on light microscopy measurements. This study was carried out with funding from the national research project 15.817.05.03F “Sunflower (Helianthus annuus L.) resistance to broomrape (Orobanche cumana Wallr.): genetic, molecular and physiological mechanisms”.
