Abstract Seed dormancy is a mechanism of long survival that ecologically important for seed propagation and dispersal the expansion plant populations. The impermeability coat in Fabaceae family due to layer sclerotic cells. Two experiments were conducted investigate effect different treatment on germination parameters seedling growth Cercis siliquastrum Spartium junceum. Experimental treatments...

Plants that form root-nodule symbioses are within a monophyletic 'nitrogen-fixing' clade and associated signalling processes are shared with the arbuscular mycorrhizal symbiosis. Central to symbiotic signalling are nuclear-associated oscillations in calcium ions (Ca(2+) ), occurring in the root hairs of several legume species in response to the rhizobial Nod factor signal. In this study we expa...

Eastern redbud, Cercis canadensis L., is a popular ornamental tree in the U.S. and has flower colors of purple-type, red-type, white-type. Most redbuds cultivars have purple-type flowers. Red-types white-types are much less common. These unusual become an important trait for incorporation into novel redbud cultivars. seedlings require 3–5 years before blooming, making color selection slow expen...

Abstract Dormancy accrual is an important process in mitigating the abiotic stressors of overwintering trees at ornamental nurseries, with frost-injured tree crops heightened risk ensuing biotic insect and disease attack. As mean global temperatures rise, nursery may lose dormancy earlier. Using potted eastern redbud (Cercis canadensis L.) placed under two types shade cloth, full sun, or walk-i...
