Petal development and senescence entails a normally irreversible process. It starts with petal expansion and pigment production, and ends with nutrient remobilization and ultimately cell death. In many species this is accompanied by petal abscission. Post-harvest stress is an important factor in limiting petal longevity in cut flowers and accelerates some of the processes of senescence such as ...

Abstract Aims To assess 1) the effect of combination flooding (winter vs. non-winter flooding; WFL vs NWF) and timing straw incorporation (early late incorporation; ESI LSI) in post-harvest paddy agrosystem, on a year-round global balance greenhouse gases (GHG) exchanges, i.e. methane (CH 4 ), carbon dioxide (CO 2 ) nitrous oxide (N O); 2) impact net ecosystem (NECB) 3) resulting warming potent...

Woolliness is a physiological disorder of peaches and nectarines that becomes apparent when fruit are ripened after prolonged periods of cold storage. This disorder is of commercial importance since shipping of peaches to distant markets and storage before selling require low temperature. However, knowledge about the molecular basis of peach woolliness is still incomplete. To address this issue...

Yacon (Smallanthus sonchifolius [Poepp. & Endl.] H. Robinson) is an under-exploited native root crop of the Andes, which stores oligofructans (fructo-oligosaccharides, FOS) as its main component of dry matter (DM). FOS are of increasing economic interest because of their low caloric value in human diets and bifidogenic benefits on colon health. Two on-farm experiments were conducted to: (i) det...

We compared the initial effects of four forest regeneration treatments (single-tree selection, group selection, shelterwood, and clearcut), and unharvested controls (mature, second-growth forest) on relative abundance of small mammals and smallmammal habitat throughout the Ouachita Mountains of western Arkansas and eastern Oklahoma. We compared small-mammal capture rates in 20 forest stands (4 ...

—Since European colonization and subsequent commercialization of Appalachian medicinal and edible plants, millions of kilograms of plant material have been extracted from our forests, with little effort to manage these species as natural resources. Roots and rhizomes of black cohosh, a native Appalachian forest herb, are extensively harvested for treatment of menopausal symptoms. As nearly all ...

Post-harvest recovery of biodiversity is one important goals in modern forestry. A variable retention (VR) approach has been particular interest North America because it promotes rapid faunal recovery, while minimizing negative lasting impacts logging on the natural fauna. We studied responses rove beetles (Coleoptera: Staphylinidae) to a broad range harvests (2, 10, 20, 50 and 75% retention) c...

Balancing timber production and conservation in forest management requires an understanding of how timber harvests affect wildlife species. Terrestrial salamanders are useful indicators of mature forest ecosystem health due to their importance to ecosystem processes and sensitivity to environmental change. However, the effects of timber harvests on salamanders, though often researched, are stil...
