A factorial experiment with two factors was carried out at the Seed Technology Lab., College of Agriculture, University Baghdad in 2018 order to study effect seed priming gibberellic acid (GA3) (0, 100, 300 and 500 mgL-1) on germination seedling growth deteriorated oat cultivars (Shifaa, Shofan11). The complete randomized design used four replications. results showed that cultivars, soaking dif...

the genus thymus is perennial medicinal plants belong to the lamiaceae familythat is used for different propose in pharmaceutical industry. environmental stresses,particularly salinity, are considered as the major factor reducing plant growth. the purpose ofthis study was to investigate the effects of salt stress on germination characteristics andseedling morphology in two medicinal species of ...

Allelopathy is a concept that applied in weed management to minimize extensively the reliance on herbicide agriculture. The allelopathic potential of Acalypha wilkesiana, Centrosema pubescens and Phyllanthus amarus Amaranthus cruentus Corchorus olitorius were investigated. Different concentrations leaf aqueous extracts A. C. P. determine their effect under laboratory conditions. profiling phyto...

Seed orientation and its impacts on germination seedling establishment mainly depend the type of (hypogeal (or) epigeal), seed size shape. Higher per cent is noticed when seeds are sown in horizontal position. Planting a downward position can lead to variety physiological, chemical morphological changes seedlings. Consequences usually manifested as noticeable modifications their development. Vi...
