Phytotoxic potential of young leaves from Blepharocalyx salicifolius (Kunth) O. Berg (Myrtaceae)

“…As observed by Pereira et al (2014), these results indicated that the roots are more sensitive to phytotoxic than the hypocotyl. Root growth is characterized by high metabolic rates, and thus, this organ is very sensitive to environmental stress (Cruz-Ortega et al, 1998). Some authors suggest that this effect is pronounced due to the intimate contact between the root and the extract (Chung et al, 2001), changing the process of lignification of the cell walls (Suzuki et al, 2008).…”

Allelopathic Effects of <i>Argemone mexicana</i> to Growth of Native Plant Species

“…Root growth is characterized by high metabolic rates and, for this reason; roots are highly susceptible to environmental stresses such as allelochemicals in soils [18]. Normal plant cell growth and morphogenesis requires regulation of the concentrations of hormones such as auxins and gibberellins [59].…”

“…Most of invasive plant species has competitive and defensive characteristics which accounts to allelopathic impact [3] [10] [14]. Allelochemicals also affect native species through different pathways that includes interruption of plants nutrients uptake, change in membrane permeability [15], interference in cell division and elongation in roots and shoots [16]- [18], interference in chlorophyll formation [19], protein synthesis inhibition [15] [20] and change or inactivate the activity and functions of certain hormones and enzymes [15] [21].…”

Adverse Effects of Allelopathy from Legume Crops and Its Possible Avoidance

“…Many researchers have done on the mechanism of allelochemicals in the legume crops [46]- [48]. Cruz et al [49] investigated the effect of allelochemicals on the P. vulgaris root where root tip cells were extruded together and that cell organization was disordered with little cell differentiation Batish et al [27] reported that the activity proteases in hypocotyl cuttings of P. aureus decreased significantly when to the caffeic acid was treated as allelochemical. Baziramakenga et al [23] studied the effects of benzoic acid and trans-cinnamic acid on growth, mineral composition, and chlorophyll content of soybean G. max grown in nutrient solution.…”
