Assessment Of Safflower Genotypes For Individual And Combined Effects Of Drought And Salinity Stress At Early Seedling Growth Stages, Fatma Kayaçeti̇n

Turkish Journal of Agriculture and Forestry

Safflower is a highly valued oilseed crop. Safflower oil is a source of monounsaturated and polyunsaturated fatty acids which are important for a plurality of industries including the edible vegetable oil industry. Safflower is highly resistant to salinity and drought stress, which impede seed germination. Two safflower cultivars and 4 lines were screened against nine levels of osmotic stress treatments (using NaCl0 and PEG 60000 (control), NaCl-0.2, NaCl-0.4, PEG 6000-0.2, PEG 6000-0.4, PEG 6000-0.2+NaCl-0.2, PEG 6000-0.2+NaCl-0.4, PEG 6000-0.4+NaCl-0.2, PEG 6000-0.4+NaCl-0.4 MPa) for 8 days at seed germination stage. The osmotic stress was observed to induce a negative effect on the …

A Comparison Of Wildfire Adaptive Traits In Juvenile Conifers Of The Northern Rockies, Andie Sonnen

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Wildfire is an importance disturbance that continues to shape the ecosystems of the northern Rockies through varying patterns of frequency and intensity. Due to historical fire suppression and the hotter and drier conditions brought upon by anthropogenic climate change, wildfire frequency and intensity is increasing. These increases will alter vegetation structure and composition, but the degree to which is unknown.

Individual plant traits can offer insight into how these vegetation communities will shift, especially the particular traits that reduce fire-related mortality. To survive wildfires, juvenile northern conifers employ two strategies: increasing their bark thickness and increasing their crown height. To …

Eastern Redcedar (Juniperus Virginiana L.) Encroachment On South-Central South Dakota Rangelands: Impact On Plant Communities, Austin K. Domeier

Electronic Theses and Dissertations

Grasslands historically covered 46 million km2 of Earth’s surface representing nearly 42% of the living vegetation. Encroachment of woody species onto grasslands and savannas is a widely researched global phenomenon, with eastern redcedar (ERC) (Juniperus virginiana L.) trees being the most prominent woody encroacher in the Northern Great Plains (NGP) due to the lack of prescribed fire and planted ERC escaping from shelterbelts. This encroachment poses a threat to native plant communities in terms of their reproduction, regeneration, and diversity. ERC are fierce competitors and can establish in most soil types, are drought tolerant, and prolific seed reproducers. These qualities …

Effects Of Buried Wood On The Development Of Populus Tremuloides On Various Oil Sands Reclamation Soils, Kaitlyn E. Trepanier, Laura Manchola-Rojas, Bradley D. Pinno

Aspen Bibliography

Buried wood is an important but understudied component of reclamation soils. We examined the impacts of buried wood amounts and species on the growth of the common reclamation tree species trembling aspen (Populus tremuloides). In a greenhouse study, aspen seedlings were planted into four soil types, upland derived fine forest floor-mineral mix (fFFMM), coarse forest floor-mineral mix (cFFMM), and lowland derived peat and peat-mineral mix (PMM), that were mixed with either aspen or pine wood shavings at four concentrations (0%, 10%, 20% and 50% of total volume). Height and diameter growth, chlorophyll concentration, and leaf and stem biomass were measured. …

Turkish Journal of Agriculture and Forestry

Determining optimal sowing date, optimal number of irrigation applications, and best-performing cultivars is critical to maximizing achievable sorghum yield in semiarid and arid environments. Limited research is available on interactive effects of sowing date, irrigation frequency, and genotype at multiple locations. Consequently, this study was conducted to determine impact of sowing dates, irrigation regimes, and cultivars on yield and growth traits during 2016 and 2017 at two locations in Pakistan. Experiments were laid out in a split-split design at Maize and Millets Research Institute, Yusafwala, Sahiwal, and at Bahauddin Zakariya University, Multan.

Yield And Oil Composition Of Peppermint Cultivars Grown In The Isparta Climate Of Turkey, Kemal Yilmaz, İsa Telci̇

Turkish Journal of Agriculture and Forestry

Peppermint, Mentha piperita L. belonging to the Lamiaceae family, contains a valuable essential oil known for its high menthol and menthone content. During the vegetation seasons of 2016 and 2017, field studies were conducted in Turkey?s Isparta climate by using randomized blocks to examine the yield and oil composition of the new peppermint cultivars. In these studies, Multimentha produced the highest herb yield even though the quality of its essential oil is relatively poor due to its low menthol content. Yield levels of other cultivars were similar to each other with the same statistical group. In the study, Citaro, Tokat …

Turkish Journal of Agriculture and Forestry

Seed coating is receiving increased relevance in sustainable agriculture, to reduce the usage of pesticides and protect the natural environment. In this study, a new formulation based on the combination of two active constituents (zinc pyrithione and triclosan) and an inactive component (carboxymethyl cellulose polymer) was optimized for seed coating to control seed-borne pathogens. According to the in vitro antimicrobial tests, the combination of zinc pyrithione and triclosan showed a broader spectrum of phytopathogenic bacteria and fungi control. Coated seeds from different plant species with 2% of zinc pyrithione, 0.05% of triclosan and, 0.5% of carboxymethyl cellulose did not show …

Super Absorbent Polymer Application Under Suboptimal Environments: Implications And Challenges For Marginal Lands And Abiotic Stresses, Asif Jamal, Sadam Hussain, Saddam Hussain, Amar Matloob, Tahir Hussain Awan, Farida Irshad, Basharat Ali, Ejaz Waraich

Turkish Journal of Agriculture and Forestry

World population is increasing at an alarming rate, and crop cultivation on marginal lands has emerged as an alternate option to feed the burgeoning population. However, marginal lands are characterized by poor soil health and other undesirable characteristics resulting in low crop production and less economic returns. Interest in the application of superabsorbent polymers (SAPs) for marginal lands has been increasing. The SAPs application increases the germination percentage, seedling growth, and grain yield of different crops. Being hydrophilic in nature, SAPs can absorb and retain a huge quantity of water, and thereby enhance the water use efficiency in crops. In …

In Silico Analysis Of The Regulatory Gene Families For Proanthocyanidins Biosynthesis In The Genus Gossypium L., Aleksandra Mikhailova, Ksenia Strygina, Elena Khlestkina

Turkish Journal of Agriculture and Forestry

The flavonoid pigments provide cotton cultivars with various shades of the naturally colored fiber. Despite of the deep knowledge about the flavonoids biosynthesis pathway in cotton, the genetic features underlying its control are not fully understood. Particularly, data on regulatory genes for the proanthocyanidins (PAs) branch are incomplete for the genus Gossypium L. Here we report results of comprehensive in silico analysis of the R2R3-Myb, bHLH-Myc and WD40 regulatory gene families, involved in the biosynthesis of flavonoid pigment PAs in cotton. For the first time, we identified regulatory genes R2R3-Myb, bHLH-Myc and WD40, including paralogous and homoeologous copies, among all …
