Strawberry is a well-known source of natural antioxidants with excellent free radical scav- enging capacity. This study determined the effects of chitosan application in field condition on plant growth, fruit yield and antioxidant activities in strawberry fruit. Foliar applications of chitosan on strawberry significantly increased plant growth and fruit yield (up to 42% higher) compared to untreated control. Increased fruit yield was attributed to higher plant growth, individual fruit weight and total fruit weight/plant due to the chitosan application. Surprisingly, the fruit from plants sprayed with chitosan also had significantly higher contents (up to 2.6- fold) of carotenoids, anthocyanins, flavonoids …

Tree Species Richness Enhances Stand Productivity While Stand Structure Can Have Opposite Effects, Based On Forest Inventory Data From Germany And The United States Of America, Laura Zeller, Jingjing Liang, Hans Pretzsch

Faculty & Staff Scholarship

Background: In recent studies, mixed forests were found to be more productive than monocultures with everything else remaining the same.

Methods: To find out if this productivity is caused by tree species richness, by a more heterogeneous stand structure or both, we analyzed the effects of forest structure and tree species richness on stand productivity, based on inventory data of temperate forests in the United States of America and Germany.

Results: Having accounted for effects such as tree size and stand density, we found that: (I) tree species richness increased stand productivity in both countries while the effect of tree …

Plant Probiotic Bacteria Bacillus And Paraburkholderia Improve Growth, Yield And Content Of Antioxidants In Strawberry Fruit, Mosaddiqur Rahman, Abdullah As Sabir, Julakha Akter Mukrta, Mohibul Alam Khan, Mohammed Mohi-Ud-Din, Giashuddin Miah, Mahfuzur Rahman, M. Tofazzal Islam

Strawberry is an excellent source of natural antioxidants with high capacity of scavenging free radicals.

This study evaluated the effects of two plant probiotic bacteria, Bacillus amylolequefaciens BChi1 and Paraburkholderia fungorum BRRh-4 on growth, fruit yield and antioxidant contents in strawberry fruits. Root dipping of seedlings (plug plants) followed by spray applications of both probiotic bacteria in the field on foliage significantly increased fruit yield (up to 48%) over non-treated control. Enhanced fruit yield likely to be linked with higher root and shoot growth, individual and total fruit weight/plant and production of phytohormone by the probiotic bacteria applied on plants. …

Parasitaemia Data And Molecular Characterization Of Haemoproteus Catharti From New World Vultures (Cathartidae) Reveals A Novel Clade Of Haemosporida, Michael J. Yabsley, Ralph E.T.

Background: New World vultures (Cathartiformes: Cathartidae) are obligate scavengers comprised of seven species in five genera throughout the Americas. Of these, turkey vultures (Cathartes aura) and black vultures (Coragyps atratus) are the most widespread and, although ecologically similar, have evolved differences in morphology, physiology, and behaviour. Three species of haemosporidians have been reported in New World vultures to date: Haemoproteus catharti, Leucocytozoon toddi and Plasmodium elongatum, although few studies have investigated haemosporidian parasites in this important group of species. In this study, morphological and molecular methods were used to investi- gate the epidemiology and molecular biology of haemosporidian parasites of …
