This study aimed at evaluating commonly used maize varieties, collected from Melkasa and Bako Agricultural Research Centers and Haramaya University, Ethiopia, against the maize weevil Sitophilus zeamais Motsch., one of the most important cosmopolitan stored product pests in maize. A total of 13 improved maize varieties were screened for their relative susceptibility to S. zeamais. The Dobie ind...

Plants that live in fragmented landscapes, where populations are isolated from each other and in which long-distance dispersal is essential for colonization of empty sites, reproduction should be favoured by self-compatibility (Baker’s law). Nevertheless, outcrossing mechanisms, such as self-incompatibility and dichogamy, are common in many species and are often maintained by inbreeding depress...

Eriobotrya japonica has been used as a medicinal plant for a long time, and its leaves are known to have many physiological actions such as anti-inflammatory, antitussive, and expectoran. In contrast, Eriobotrya japonica seeds are only known to contain amygdalin, and almost no investigations of its pharmacological action have been performed. Moreover, some anticancer agents such as adriamycin c...

Isabgol is a major export oriented medicinal crop of India. The genetic variability available in this crop is limited owing to the narrow gene pool existing in our country. The physiological and growth characteristics of selected 7 species of Plantago were studied at DMAPR, Boriavi to investigate the relationship with the seed yield. Among the species studied, the lowest SLA (specific leaf area...

Seed banks play a crucial role in arid plant communities because they confer stability and longterm persistence. However, seed banks have high temporal and spatial variability, with dramatic changes in density and composition. The aim of this study was to test whether seasonal change affected seed bank community structure and spatial pattern. Moreover, we wanted to know if the effect driven by ...

in order to study the phenological and morphological characteristics, comparison of yield and yield components, correlation between traits and determination of the parameters affecting seed yield, a field experiment was carried out at the research farm of shahrekord university in 2007. ten lentil genotypes were compared by a randomized complete block design with three replications. the analysis...

The effect of electromagnetic field was examined on Zinnia (Zinnia elegans) seeds to enhance seed germination and early growth. The seeds were exposed to four magnetic strengths of 15, 100, 400 and 800 mT in four durations of 30, 60, 120 and 240 min. The experiments were carried out in two forms of laboratory germination and soil emergence. Results showed that magnetic field application enhance...

                In order to determine the best developmental stage of three common bean cultivars (Talash, COS16 and Khomain) at which maximum seed quality is attained under different irrigation regimes (I1-irrigation after 60 mm, I2-irrigation after 80 mm and I3-irrigation after 100 mm evaporation from class A pan), a split plot experiment (using R.C.B. design) with 3 replications was conducte...
