Triticale (X Triticosecale Wittmack) is an artificial hybrid of wheat (Triticum sp.) and rye (Secale sp.) first bred in laboratories during the late 19 century. In little more than a century, triticale has developed from a biological curiosity to a practical crop. Plant breeders have made efforts to overcome main problems of triticale: preharvest sprouting, susceptibility to diseases, sensitivi...

ABSTRACT Cyclic hydroxamic acids are secondary metabolites found in the family Poaceae and have been implicated in the allelopathy of rye (Secale cereale). The toxicity of these compounds against plant-parasitic nematodes is unknown. DIBOA (2,4-dihydroxy-(2H)-1,4-benzoxazin-3(4H)-one), DIMBOA (2,4-hydroxy-7-methoxy-(2H)-1,4-benzoxazin-3(4H)-one), and their degradation products BOA (benzoxazolin...

Soil erosion is a major threat to global economic and environmental sustainability. This study evaluated long-term effects of conservation tillage with poultry litter application on soil erosion estimates in cotton (Gossypium hirsutum L.) plots using RUSLE 2.0 computer model. Treatments consisting of no-till, mulch-till, and conventional tillage systems, winter rye (Secale cereale L.) cover cro...

The transport of runoff with high copper concentrations and sediment loads into adjacent surface waters can have adverse effects on nontarget organisms as a result of increased turbidity and degraded water quality. Runoff from vegetable production utilizing polyethylene mulch can contain up to 35% of applied copper, a widely used fungicide/bactericide that has adverse effects on aquatic organis...

The seed storage proteins (SSPs) of cultivated wheat (Triticum aestivum and T. durum), namely, glutenin and gliadin, impart viscoelastic properties to bread dough, making wheat well suited for bread-making. Extensive studies on wheat SSPs have been carried out and revealed genetic diversity among wheat cultivars. Here, we review the studies of SSPs from more exotic species in the Triticeae trib...

salinity stress is one of the most important abiotic stress factors limiting the plants' growth. seed priming is known as a method which improves the germination performance in seeds in stress conditions. the objective of this study was to compare the effectiveness of hydropriming and halopriming on germination performance of secale montanum while growing under the nacl-salinity stress. hydropr...
