Zonal management of cereal–legume cover crop mixtures may help address weed and nitrogen challenges common in organic reduced tillage systems. During a field study conducted over 3 years Michigan, we evaluated the effects management, tillage, supplemental mulch on organically produced acorn squash ( Cucurbita pepo ). fall season before production, rye Secale cereale L.) vetch Vicia villosa Roth...

objective(s):the aim of this study was to evaluate distribution and changes of glycoconjugates of retinal photoreceptors during both pre- and postnatal development. materials and methods: tissue sections from days 15 to 20 of wistar rat embryos and 1 to 12 postnatal days of rat newborns including developing eye were prepared for lectinhistochemistry technique. horseradish peroxidase (hrp)-label...

The floor plate is a small group of cells located at the ventral midline of neural tube. During early neurogenesis the floor plate plays critical role (s) in differentiation of ventral portion of neural tube.The purpose of this study was to determine the distribution of glycoconjugates in floor plate as well as underlying mesoderm (notochord) and their inductive activities in mouse embryos.Form...

Background: The aim of this research was to study the distribution and changes of glycoconjugates particularly their terminal sugars by using lectin histochemistry during mouse spinal cord development. Methods: Formalin-fixed sections of mouse embryo (10-16 fetal days) were processed for lectin histochemical method. In this study, two groups of horseradish peroxidase-labeled specific lectins we...

Biological nitrogen fixation (BNF) is a key ecosystem service rendered by legumes, but quantitative information lacking regarding BNF in the Texas Rolling Plains (TRP), an easterly portion of U.S. Southern Great where cool-season legumes can typically be grown as cash or cover crops dryland conditions. Using three diverse cropping systems studies (Site 1, long-term cotton [Gossypium hirsutum L....
