Secondary succession of overgrazed Pannonian sandy grasslands [PDF]

open access: yes, 2008
We assessed vegetation changes on acidic sandy soils in permanent plots to follow secondary succession after cessation of intensive goose breeding in E Hungary.We also aimed to estimate the time required for vegetation regeneration and indicate ...

Progress and bottlenecks in the early domestication of the perennial oilseed Silphium integrifolium, a sunflower substitute [PDF]

open access: yes, 2018
Silflower (Silphium integrifolium Michx.) is in the early stages of domestication as a perennial version of oilseed sunflower, its close relative. Grain crops with deep perennial root systems will provide farmers with new alternatives for managing soil ...

Spatial patterning of chloroplasts and stomata in developing cacao leaves

open access: yesCommunications Biology
Leaf development and the coordinated formation of its key components is a fundamental process driving plant growth and adaptation. In tropical species like cacao, flush growth, a period of rapid leaf expansion, is particularly dependent on the optimized ...

Enabling the study of gene function in gymnosperms: Virus‐induced gene silencing in Ephedra tweedieana

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise As the sister clade to angiosperms, extant gymnosperms are crucial for reconstructing ancestral gene regulatory networks in seed plants. This highlights the need for model systems representing each of their distinct lineages. However, tools to quickly and effectively investigate gene function in gymnosperms are still limited due to the

Grazing intensity affects the composition and spatial heterogeneity of plant functional groups in a desert steppe

open access: yesGlobal Ecology and Conservation
The spatial heterogeneity of plants within a community reflects the distribution of species and their responses to grazing disturbance. Understanding these processes is essential for clarifying the dynamics and stability of plant community structure ...

Persistence of Overseeded Cool-Season Grasses in Bermudagrass Turf

open access: yesInternational Journal of Agronomy, 2011
Cool-season grass species are commonly overseeded into bermudagrass turf for winter color. When the overseeded grass persists beyond the spring; however, it becomes a weed.

A Review of Modeled Water Use Efficiency of Highly Productive Perennial Grasses Useful for Bioenergy

open access: yesAgronomy, 2020
Whole plant productivity is obviously the ultimate product of leaf photosynthesis and this has led to numerous efforts to relate the two. However, often with perennial grasses, plant productivity is more sink-limited than source-limited, causing the ...

Managing Sonchus arvensis using mechanical and cultural methods [PDF]

open access: yes, 2006
Perennial sow-thistle (Sonchus arvensis L.) represents an increasing problem in Finland. Options for mechanical and cultural control of S. arvensis were studied in a field experiment on clay soil under organic production.
