The Relationship

The relationship between breaking of dormancy of wild barley (Hordeum spontaneum C. Koch) caryopses and revival ability of young seedlings from a long period of desiccation was studied using barley caryopses stored for 2 years at 5°C and freshly harvested caryopses from a semiarid population in Israel. The 2 years of storage at 5°C significantly enhanced the germination percentages, but dramatically decreased the revival ability of the young seedlings from drought stress. There was a negative correlation between the breaking of dormancy of caryopses and revival ability. There were no significant changes in the effects of storage at a high temperature for periods longer than 5 days. The earlier germination occurred, the higher the revival ability of young seedlings from drought. The results suggest that breaking of dormancy might be at the expense of lowering the subsequent revival ability of young seedlings. The general premise is that a trade-off is expected between dormancy release of caryopses and revival ability of seedlings from drought stress, and that a treatment that aims at breaking dormancy must reach some compromise that optimizes the balance between the two traits based on the specific circumstances.Key words: dormancy breaking, caryopses, revival ability, seedlings, Hordeum spontaneum, wild barley.

Wild oat (Avena fatuaL. ♯3AVEFA) andAvena sterilisL. ♯ AVEST accessions from the United States were screened for tolerance to diallate [S-(2,3-dichloroallyl) diisopropylthiocarbamate], triallate [S-(2,3,3-trichloroallyl) diisopropylthiocarbamate], barban (4-chloro-2-butynylm-chlorocarbanilate), diclofop {2-[4-(2,4-dichlorophenoxy) phenoxy] propanoic acid}, difenzoquat (1,2-dimethyl-3,5-diphenyl-1H-pyrazolium), flamprop [N-benzoyl-N-(3-chloro-4-fluorophenyl)-DL-alanine], and MSMA (monosodium methanearsonate). Some accessions were tolerant to more than one herbicide but none were tolerant to all herbicides. Tolerance to a herbicide was not restricted to certain areas of origin of the accessions, and tolerant accessions occurred even in locations that had not been treated previously with the herbicide. In general, accessions from Southern California and Arizona were shorter, produced more tillers, and required the least number of days to panicle emergence. However, accessions from within individual areas were nearly as variable in these characteristics as the entire 1200 accessions. Tolerance of accessions to flamprop, difenzoquat, MSMA, and diclofop was not due to low leaf surface area, since the tolerant accessions usually had the most leaf surface area. All the accessions tolerant to difenzoquat, MSMA, and flamprop, and three of the four accessions tolerant to diclofop, tillered less than the susceptible accessions.
