Pearl Millet Cover Crop Extract Inhibits the Development of the Weed Ipomoea grandifolia by Inducing Oxidative Stress in Primary Roots and Affecting Photosynthesis Efficiency. [PDF]

Plants (Basel)
The cover crop Pennisetum glaucum (L.) R.Br. (pearl millet) reduces the emergence of weed species in the field through a mechanism that is not fully known. The identification of the allelopathic activity of pearl millet can contribute to the development of no-tillage techniques to produce crops without or with low doses of herbicides.

Efeito do déficit hídrico na eficiencia de herbicidas e nas características bioquímicas de Ipomoea grandifolia [PDF]

Planta Daninha, 2012
O objetivo deste estudo foi avaliar a eficácia dos herbicidas inibidores da ALS e PROTOX no controle de Ipomoea grandifolia sob dois níveis de déficit hídrico, bem como determinar a influência desse déficit hídrico sobre o conteúdo de carboidratos solúveis, proteínas totais e aminoácidos livres da planta daninha.

From leaf to label: A robust automated workflow for stomata detection. [PDF]

Ecol Evol, 2020
Our paper proposes a newly developed methodology for automatic stomata detection using deep neural networks according to the state of the art and demonstrates its applicability across the phylogeny of the angiosperms. Abstract Plant leaf stomata are the gatekeepers of the atmosphere–plant interface and are essential building blocks of land surface ...

Phytotoxic Potential of the Crude Extract and Leaf Fractions of Machaerium hirtum on the Initial Growth of Euphorbia heterophylla And Ipomoea grandifolia [PDF]

Planta Daninha, 2019
ABSTRACT: Allelopathy is the term used to define any process involving secondary metabolites produced by plants and microorganisms that influence growth and development of agrobiological systems. Currently, it is sought to find allelochemicals of interest and know how to apply them in bio-herbicides to combat weeds.

Woody and Herbaceous Species Diversity Respond Differently to Environmental Variables in Semiarid Areas in Ghana. [PDF]

Ecol Evol
In the drylands of Ghana, the relative importance of various environmental drivers for plant species composition and diversity is still poorly understood and this affects the identification and implementation of appropriate management strategies.
