The Effect Of Salinity On Resistance, Proline, And Mineral Nutrients

First, before starting my experiment I did some research on the growth of lima beans, so that I could start the base of the project. According to research done at the University of

The pH of soil is important for the absorption of nutrients into the plant. Of the 17 needed plant nutrients 14 of them are acquired through the soil. Acidity is needed to break down and dissolve these nutrients. The nutrients are able to dissolve into the soil faster when the acid is acting as a solute. Another way the pH affects the soil is by influencing microorganisms. The bacteria is crucial in the growth and development of the plant, the bacteria’s role is to break down and decompose organic matter in the soil. If the pH of the soil is too high the acid will slow down and eventually stop the microorganisms. Most plants ideal pH is between 6-7, slightly acidic. Many plants are outliers and thrive in pH such as carrots and corn, which can withstand pH as low as 5.5. If the pH of the soil is too high for the desired crop farmers can add material such as limestone, and wood ashes to raise the pH to the desired level. The pH of the soil can also be changed naturally through the leaching of calcium, magnesium and sodium by rainwater. Carbon dioxide from rotting organic matter can also increase the pH of the soil. Acids can also be created organically in the form of sulfuric and nitric

The purpose of this lab was to investigate and observe the effects of organic vs. synthetic fertilizers on plant growth by planting lima beans with added amounts of fertilizers, and to see how does adding different nutrients to the soil affect the growth of the lima bean? A significant difference was examined between the plants that contained manure and miracle growth, unfortunately the plant with no additional fertilizers (Plant #3) did not show any growth. The plant that grew the most was the one that contained manure, to an extent the one that grew the most in a short period of time was the one that contained miracle growth, as shown in figure I. The hypothesis explaining if the Lima Bean plant contains synthetic nutrients in the soil then

While experimenting with the green beans, the seeds exposed to the organic plant food germinated within five days of the experiment and the seeds exposed to the chemical plant food germinated within six. The seeds that acted as the control had been expected to grow the least, however, it was surprising that they did not grow at all. Both the chemical and organic fertilizers proved to have positive results on the plants. It was also unexpected when the seeds exposed to the chemical plant food surpassed the height of the other experimental seeds after being shorter. The predicted reason for the increase in growth with seeds given Miracle Grow was because chemical fertilizers automatically store up the nutrients and disperse it constantly throughout

Therefore, a 20-day laboratory incubation experiment was conducted to evaluate the influence of nitrification inhibitors on N2O, CO2 and CH4 emissions after the incorporation of broccoli crop residues on a heavy-clay, vertosol soil from Gatton, South East Queensland, Australia. Five treatments were investigated including the conventional fresh broccoli residue incorporation, with the addition of three nitrification inhibitors: 3,4-dimethylpyrazole phosphate (DMPP), 3,4-dimethyl pyrazolium glycolate (DMPG), and PIADIN. The incorporation of dry broccoli residues was also investigated. Samples were incubated at 25 ̊C across varying soil moisture

The problem is to find out what effect does/do closed jars have on plant growth? How does/do water and humidity and sunlight determine a plant's health and how much it will grow? What amount of water and sunlight is optimal for plant health and growth? How do different types of potting soil affect a plant’s growth? These questions have guided me through my project and helped me find out the pieces of information to solve these problems.

Widmer and Associates has been a dealer for Stoller products for the last 30 years. The Stoller company started out as a micronutrient and fertilizer manufacturer. Jerry Stoller realized there was something more to increasing crop yields than just proper fertilization alone. It seemed that the stress that weather places on a plant can be more profound than adequate fertilization of a crop can overcome. Natural plant hormones and their roles and effects that seem to have as great of an effect on yields as soil fertility. This is the same thought process we have at Widmer and Associates. Stoller scientists recognize certain principles in crop production that are common to all plant species when exposed to biotic and abiotic stresses. It is not

What we were trying to find with this experiment was recommend soil salt concentrations, soil pH levels, and optimize light bulbs, for a greenhouse growth of different types of potatoes. We did this by determining ideal soil salt concentrations by calculating percent mass change in potatoes at various salt concentrations, determining optimal pH for maximum catalase activity, and using a spectrophotometer to determine the absorbance of pigment extracted from leaves. In the first experiment, we were able to find that the concentration that was hypotonic to potato cells would be 0.0M NaCl. While the salt concentrations that are hypertonic to the potato cells are 0.2 M NaCl, 0.4 NaCl, and 0.6 M NaCl.

“In the same way that humans have bred plant species together over the centuries to create oats, maize, and wheat, so too can we breed desiccation-tolerant (the ability of an organism to withstand or endure extreme dryness or drought-like conditions), drought resistant crops in the Eragrostis (a family of perennial grasses) family without having to go the genetically modified route.” She explains that all plants have the genes that enable tolerance to periods with a lack of water, but most only use them when they make seeds. Resurrection plants, however, can also switch these genes on in their leaves and roots whenever water isn’t available. In response to desiccation, the cellular activity in resurrection plants can be summarized as: Dehydration -> Activation of desiccation related genes -> Alterations in metabolism (Accumulation of protective solutes such as sucrose, trehalose, and proline that stabilize proteins and cellular membranes. Production of antioxidant compounds such as galloylquinic acids. Biochemical alterations in membrane and cell wall composition.) -> Production of protective proteins (“dehydrins” and “expansins” that help preserve the structure of the cell walls of the

Nitrogen, potassium, calcium, magnesium, phosphorus, and sulfur are all macronutrients. Chlorine, iron, boron, manganese, zinc, copper, nickel, and molybdenum are all micronutrients. Nitrogen is needed for the chlorophyll of the plant. The relative number for nitrogen is 1,000,000. It helps speed up the growth of a plant. Phosphorus is a key element in order for plants to maintain photosynthesis. Potassium is also a key element for plants to maintain photosynthesis. However, it also helps limit diseases, and is the element responsible for getting plants protein. Magnesium energizes plant enzymes that are essential for growth. Sulfur helps boost the growth of roots. Zinc helps control sugars. Fertilizers also help plants grow and develop. There are four categories of fertilizers; synthetic fertilizer, organic fertilizer, slow release fertilizer, and fast release fertilizer. Synthetic fertilizers are manufactured. Organic fertilizers are made from natural materials. Fast release fertilizers quickly release nutrients to plants. Slow release fertilizers limit the loss of nutrients. (Streich, etal)

Water is the most natural thing we have on earth. It sustains many organisms and those organisms depend on it almost daily. Plants are such organisms. For this study the focus is the growth of beans. Over the course of two weeks my team and I conducted research comparing the two types of waters that were selected and seeing if they had any significant differences in growing beans. The first week was inconclusive due to bean rot and negligence. Test two led to a more constant observation of growth and change of location. Results gathered from this experiment have shown a difference that different waters may have on the growth of plants. Beans that consumed certain water sources

The hindering of the Benzoquinone could alter the production, and could lower the cost of produce. Nathalie Santis and others (2005) preformed an experiment to see the effects of various NaCl solutions on thin slices of potato that were fried. The potatoes were sliced 3mm thick and 30mm in diameter, fourteen slices in all. All fourteen were blanched at 70°C for five minutes. Seven were placed in pure water at 26°C and the other seven went into several NaCl solutions (0.6%, 1.2%, 1.8%, 2.4%, 3.0%, 6.0% and

Seeds from different capsicum plants were purchased locally. The pepper seeds collected were ‘Japanese chili’, ‘California Bell’, ‘Serrano’, ‘Habanero’, and ‘Jalapeno’.

All plants are subjected to a multitude of stresses throughout their life cycle. Depending on the species of plant and the source of the stress, the plant will respond in different ways. When a certain tolerance level is reached, the plant will eventually die. When the plants in question are crop plants, then a problem arises. The two major environmental factors that currently reduce plant productivity are drought and salinity (Serrano, 1999), and these stresses cause similar reactions in plants due to water stress. These environmental concerns affect plants more than is commonly thought. For example, disease and insect loss typically decrease crop yields by less than ten percent, but severe
