Salinity is one of the most abiotic stress destructive factors which limit growth and production of date palm offshoots considerably. In order to investigate the effects of antioxidant compounds on growth parameters as indicters to salt tolerance at the date palm offshoots cultivars of Kabkab (female) and Ghannami ahmer (male). Experiment was conducted with seven treatments and four replications for each treatment to each cultivar. Offshoots received (Control treatments once without salt water and another with salt water, spraying citric acid at 800 ppm, spraying ascorbic acid at 600 ppm, soil injection by Acetyl salicylic acid at 2000 ppm (aspirin), soil injection by acetyl salicylic acid at 2000 ppm + spraying citric acid at 800 ppm and soil injection by …show more content…
Many compounds as citric acid, Ascorbic acid and salicylic acid act as antioxidant and scavengers of ROS. Recently, antioxidants are suggested for improving salt tolerance in plants, these compounds as non-enzymatic materials have beneficial effects on scavengers of ROS. Citric acid is considered now as one of non enzymatic antioxidants which act to eliminate free radicals produced in plants under stress in plants (Yan-Lin and Soon, 2001). It is an important substrate in Krebs cycle. In addition, the cycle provides precursors including certain amino acids as well as the reducing agent NADH that is used in numerous biochemical reactions. So, it plays an important role in stimulating biosynthesis processes (Abd El-Al, 2009). *Correspondingauthor: Hussein J. Shareef Department of Date Palm Varieties, Date Palm Research Center, University of Basrah, Basrah, Iraq Ascorbic acid is an important primary metabolite in plants that functions as an antioxidant, an enzyme cofactor and a cell signalling modulator in a wide array of crucial physiological
Hypothesis: If one-day pinto bean seedlings are soaked in a water solution, 1% NaCl solution, and 3% NaCl solution, the seedlings exposed to higher sodium concentrations will have decreased cellular respiration rates. Treatments: This experiment involved three treatments and a control. The goal of the experiment was to see how different levels of NaCl affect the rates of cellular respiration in day-old pinto bean seedlings.
The article “Which Plants Can Tolerate Salt” explains how Rugosa Roses and Begonias can possible survive in salt water through an experiment. In the experiment, it has predictions and data. It also has an analysis, charts, pictures, and a conclusion for the readers to help understand the experiment. After reading the experiment, readers can figure out through the findings that roses thrived in the salty environment,
In this lab experiment the effects of plant growth and the pattern of plant growth in a lima bean plant had been eye opening. Using different liquids had a different outcome on each plant. the different types of nutrients and PH level in each liquid played various roles in the development and growth of each plant. the plant that had been exposed to sprite and milk showed a effective growth and decay starting from day 5. An incredible 3.2 cms was the growth for the plant which was exposed to pond water and on day 5 the plant that was exposed to the liquid of naturel 2% milk showed a decrease of .2 cms.
Sor Juana Inés De La Cruz dedicated her whole life to studying, even joining a covenant to continue acquiring knowledge as she grew older. She was famous for her poems and plays, and the Respuesta do Filotea De La Cruz, in which she questioned her own role in society as well as other women, disputing an argument brought up by “Sor Filotea De La Cruz” that ridiculed her literature and her actions.
Back in the day, men wore masks to hide their identity so they could go around town and beg for offerings to help make their gumbo, but today masks are worn to hide the identity of revelers. Mardi gras face masks have a tradition which goes back to centuries, and they represent a number of many different things. The most common and oldest mask is the Colombina, which only covers the eyes and mouth of the person wearing it. It is worn to represent a person who is loving and intelligent. Another most common type of mask is a red and black mask that covers the whole face of a person which you will see throughout the entire city of New Orleans.
If a plant is receiving a higher concentration of salt minerals in the water a nutrient imbalance will occur inside the plant, thus resulting in poor or little plant growth. Salinity level tests should regularly be carried out by home gardeners to ensure the best quality produce, salinity level test results which display salt levels more than 320 parts per million should not be used to water plants. Mineral nutrients are another important factor to successful plant growth, in home gardens, these nutrients are found in the soil and additional fertilisers, however, these levels of nutrients can be accidentally altered by excess salts, resulting in plant dehydration and possibly death. Found in soil, potting mix and other mediums in which plants typically grow in contain oxygen in which the plant needs to successfully grow.
The way plants are able to provide the entire food chain with nucleic acids is that because of the phosphorous and nitrogen cycle, it is able to absorb these two elements and create its own nucleic
Methods Dry Phaseolus vulgaris (Navy beans) were purchased from the local grocery store. A handle full of beans were sifted through to remove any beans that were damaged or halved. The beans were then filtered by size to remove beans smaller or larger than 1.5 cm. Removing the abnormal beans lessened the possibilities of variation in plant growth. The remaining beans were soaked in room temperature mineral water for 1 hour to accelerate germination.
Catechol oxidase is found in cell cytoplasm, their function in plants are to "help protect damaged plants bacterial and fungal disease." The objective of this experiment is to test the presences of catechol oxidase in various fruits and vegetables. Our group hypothesis states that, If catechol oxidase is present in the selected extracts, the null hypothesis is that catechol oxidase is not present in the selected extracts. Next, the prediction would be, if catechol oxidase doesn't differ with other enzyme sources, then the rates will

This article searches through the different types of victimization.
Since nitrogen is important component in the plant growth, the agriculture community will produce low yields in their crops. Name three carbon fixation pathways Three carbon fixation pathways are: the reductive citric acid cycle, the hydroxypropionate cycle, and the acetyl-CoA pathway. Are all phototrophs autotrophs?
All organisms use food molecules, like glucose to produce ATP. The production of ATP occurs during cellular respiration. ATP provides the cells with energy that is necessary to produce oxygen. The seeds/plants are autotrophic organisms, which produce their food from the energy that the light provides them. To release the stored energy within the food molecules, the germinated seeds carry out respiration and the release of carbon dioxide.
In western society, the depiction of health usually presides in skin tone. No one wants to be “pale” or “pasty”, so being tan is encouraged like a fashion trend. The tanning salon industry is skyrocketing along with the trend of “soaking up the sun”. It is little known that the “glorious” tan that everyone wants to achieve by sitting out in the sun for a few hours is a defense mechanism designed by the body to stop the harm that ultraviolet rays (UV rays) may cause it. UV radiation has detrimental effects on the human body.
Introduction Plants are a major necessity in the balance of nature, people’s lives, and our terrain. We may not realize it, but plants are the ultimate source of food for almost 95% of the world population so says the National Group of Food. It’s a fact that over 7,000 species of plants are being consumed today. Plants are one of the reasons that we get clean water; as they help regulate the water cycle.
