Identification of soybean circular RNAs in response to low nitrogen and phosphorus stress
Soybean, one of the most important sources of edible oil and protein in the world, is exposed to various environmental biotic and abiotic stresses. These stresses can negatively impact the quality and quantity of soybean production. This study aimed to identify genes that express circular RNAs in response to low phosphorus and nitrogen stresses in soybean roots. Soybean seeds were grown under d...
متن کاملPredicting Nitrogen and Phosphorus Concentrations using Chlorophyll-a Fluorescence and Turbidity
Introduction High sedimentation and nutrient loading is a major issue leading to undesirable water quality conditions, especially in extensive agricultural systems (Turner and Rabalais 2003). Eutrophication in both inland and coastal systems has shown to be deleterious to aquatic ecosystem functioning (Dodds and Whiles 2010). Controlling excess nutrients such as phosphorus and nitrogen can slow...
متن کاملNursery response of container Pinus palustris seedlings to nitrogen supply and subsequent effects on outplanting performance
Container longleaf pine (Pinus palustris) seedlings often survive and grow better after outplanting than bareroot seedlings. Because of this, most longleaf pine are now produced in containers. Little is known about nursery fertilization effects on the quality of container longleaf pine seedlings and how that influences outplanting performance. We compared various fertilization rates (0.5, 1, 2,...
متن کاملThe effect of water deficit stress on chlorophyll fluorescence, photosynthetic pigments, trigoneline and grain yield in fenugreek in response to zeolite and nitrogen
In order to determine the effects of water deficit stress, nitrogen fertilization and zeolite on chlorophyll fluorescence, pigments, trigonelline content and seed yield in, a split factorial experiment was laid out in a randomized complete block design with three replications. Five irrigation regimes were randomly applied to the main plots. Subplots included six treatments and consisted of a fa...
متن کاملGenetic Survey of Pinus Radiata. 4: Variance Structures and Heritabilities in Juvenile Clones
A clonal adjunct to a large Pinus radiata D.Don provenance-progeny trial involved six populations (all the natural populations except Cedros, plus two "land-race" populations from New Zealand) x 30 wind-pollinated progenies (families) x two clones nested within each of two sites x four ramets per clone. The clones were cuttings taken from previously hedged 3-year-old ortets at c. 55 cm height, ...
