setting, large seed size , high growth rate and high Harvest index. The productivity of pigeonpea has been hampered by several abiotic factors such as waterlogging, salinity, heat and heavy metals. Among them, waterlogging is the main constraint and it is estimated that each year more than 30% of the pigeonpea growing areas suffer by water-logging (ICRISAT, 2009). In India average yield losses of pigeonpea crops are estimated at 0.32 m tons, costing about US$22 m (ICRISAT, 2009). A key feature of waterlogging is depletion of oxygen which leads to number of problems such as, alteration of plant morphology and metabolism, and inhibition of photosynthesis, chlorophyll degradation and early leaf sencencse (Voesenek and Bailey-Serres, 2013; Jackson and Colmer, 2005). In plants the formation of aerenchyma is a marker adaptive response to flooding or waterlogging (Thomas et al., 2005). Plants respond to waterlogging by producing metabolic energy from fermentative glycolysis rather than from oxidative respiration (Kumutha et al., 2008; Ismail et al., 2009; Capon et al., 2009). Waterlogging accelerates the production of ethylene hormone which plays important role the formation of adventitious roots (Shiono et al., 2008; Chen et al., 2002). Ethylene induced adventitious roots formation has been considered to be a major adaptive mechanism to waterlogging stress (Pezeshki, 2001). In India, waterlogging is one of the major problems for the pigeon pea production and productivity, where…

to the experiment may be adding more samples, monitoring every day, better organisation and collaboration between the class to get more accurate results, and adding more amounts of gibberellic acid to avoid drying and to increase germination. A follow up experiment may be how gibberellic acid affects the growth of the plants over time. Conclusion Hypothesis Ha1 that states that higher concentrations of gibberellic acid (500 to 1000 ppm.) will promote the germination of the Eruca sativa seeds has…

Walking down the trail the branches covered in leaves were close enough to tickle my shoulder. Flowers of bright, vibrant colors were everywhere. I could see red, pink and blue colors, it was as if I was looking at a rainbow, but-they-were-flowers. Suddenly this amazing sweet smell entered my nose, the smell turned into a taste that made my mouth water, what is that? Kiwi, my scented hand lotion, it is Kiwi hand lotion, the smell is adding to the beauty that surrounds me. Why are all these…

line in Graph 1. Moreover, since the concentrations differed only by 0.25g/mL, then the probability concocting inappropriate E. microcorys substances became more probable between the middle three concentrations. Though, if the data collected 0.5g/mL was treated as outliers, then the E. microcorys allelopathic effect on the R. sativus seeds would be discerned more clearly and precisely. The implications of data to a pertinent situation would have included further support for the use of…

As leaves change from a vibrant green to beautiful shades of red orange and yellow, you can't help but wonder how and why the leaves produce such stunning colors, and why they fall off the trees? As stated in Robert Krulwich, Why leaves really fall off trees, “Once the green is gone, two other pigments show their bright faces.” We will be exploring everything involving autumn leaves. We can't talk about fall leaves without mentioning fall. Fall is called so because, leaves fall of the…

Germination- Germination is when seeds are spread/blown somewhere else and grow into new plants or when a seed is planted by someone in the ground. Although there are many important factors that are involved in seed germination the three most important ones are water, sunlight, and temperature. Plants are not able to germinate if the seed is watered too much or too little. Plants are not capable to grow food from sunlight when they are seeds, so the seed will use other things, such as water, to…

measures. The study also aims at the effect of different heights on the genetic diversity of plants O. ficus and the study of biodiversity within this species. Where it is important in the ecosystem of the reserve. Using a technique inter-simple sequence repeat (ISSR) (Spooner,2005). This technique applied genetic identity study of O. ficus and useful for taxonomic studies of closely related O. ficus species. In addition, ISSRs involving gene mapping studied of the O. ficus. ISSRs are DNA…

Brinly Knight Mr.Hales Science, P3 11-14-14 Is the Spider Monkey Worth Saving? There are less than 2,000 packets of spider monkeys left in the world. Also spider monkeys give birth to only one offspring every three to four years. The spider monkey is not worth trying to save. There are many reasons of why they aren’t worth saving. Some of these reasons include money, reproduction, and the activity of spider monkeys. Spider monkeys live in the tropical…

As I make my precarious way into the wood, it seems my cautious tip toeing is pointless, for with every step a twig or a leaf snaps underfoot. Nevertheless, I continue on, the sound of my footsteps reverberating with an impossible loudness through the surrounding foliage. I gaze upon the towering trees around me, noting that the mottled skin of their branches bear a pleasant resemblance to my own flesh; the burn scars which race up and down my whole body a constant reminder of my task. The wind…
