Plant-herbivore interactions are among the most common of ecological interactions. It is therefore not surprising that plants have evolved multiple mechanisms to defend themselves, using both constitutive chemical and physical barriers and by induced responses which are only expressed after herbivory has occurred. Herbivores, on the other hand, respond to these plant defenses by evolving counte...

A systematic approach for fish shelf life modelling and Time Temperature Integrator (TTI) selection in order to plan and apply an effective quality monitoring scheme for the fish chill chain was developed. The temperature behaviour of the natural microflora of the Mediterranean fish boque (Boops boops) was studied and growth of the specific spoilage bacteria Pseudomonas spp. and Shewanella putr...

The aim of this study was to evaluate the effect of Supplementations of teff (Eragrostis teff (ZUCC.) Trotter) grain flour to wheat flour at 0, 5, 10, 15 and 20% levels on organoleptic and nutritional evaluation of the supplemented bread. Protein, moisture, ash and falling number as well as rheological evaluation were estimated for prepared flour blends and dough. Besides, organoleptic assessme...

Genetic improvement of native crops is a new and promising strategy to combat hunger in the developing world. Tef is the major staple food crop for approximately 50 million people in Ethiopia. As an indigenous cereal, it is well adapted to diverse climatic and soil conditions; however, its productivity is extremely low mainly due to susceptibility to lodging. Tef has a tall and weak stem, liabl...

In the past and now most of the developments in conventional agriculture have concentrate on major grasses with little attention to the minor, underutilized grasses and as yet undeveloped grasses of livestock. Many underutilized grass species are being lost each day and more of which have unknown potential will be lost. The present study is undertaken to carry out the nutrient content of twenty...

Epidermal conductance (gmin) is water lost through the cuticle and stomata of plants when stomatal conductance is minimal. Low gmin may affect survival of perennial grasses by maintaining tissue hydration during drought. If true, populations from environments where drought is severe may exhibit reduced gmin compared to those from less arid environments. Success of invasive grasses may also be a...
