ABSTRACT: The response of Phaseolus vulgaris to increased levels of saline solution at germination and seedling growth was investigated. Seeds were germinated in paper towels placed in plastic Ziploc bags with varying concentrations of saline solution and incubated at 25°C. At the end of 14 days the seeds were removed and observations and measurement of any root and shoot growth were taken. There was insignificant or no germination in most of the sampled beans with an

Make sure the paper towels remain moist for the duration of your experiment | | | | | | | | | | Procedure 1. Think of 10-20 variables that may affect seed germination‚ recording them in Table 3. 2. From your list of variables in Table 3‚ select three to test. Form a hypothesis for why each affects seed germination. 1. Cold Temperature 2. Water (presoaked) 3. Warm Temperature 3. To germinate the beans‚ place one folded paper towel‚ moistened but not soaking

originates in East Africa and is the oldest of the commercial oil seeds. The oil is a clear edible oil with a pleasant taste and a very good long shelf life if properly refined. Sesame has an oil content of 48-55% which is the highest of any oil crop while the protein content ranges from 44 to 48%. Sesame seeds are either consumed directly as a highly nutritious foodstuff or processed by the confectionery and bakery industries. The seed hulls‚ which are bitter due to their oxalic content‚ can be removed

also added the same amount of soil to each small pot as well as giving each pot containing seeds the exact amount of water each day. Each of the pots was kept in three separate containers which were all identical only the colour of the handles of each container being different.

walls of some tissues‚ providing structure for plants to grow upright and space for vascular tissue. • Reproducing on land: A pollen grain is a two-celled structure produced by seed plants that contains a cell that will divide to form sperm. Pollen can be carried by wind or animals to female reproductive structures. A seed is a storage device that also protects and nourishes a plant embryo. Plants evolve with other organisms in their environment. • A mutualism is an interaction between two species

2.3.3 Effects of heavy metals on plants Plants are sensitive for both‚ deficient and excess availability of some of the heavy metal ions. In which some of them at low concentration are compulsory micronutrients‚ while the same at higher concentrations such as Cd‚ Hg‚ As are intensely toxic to the metabolic activities of the plants (Reeves and Baker‚ 2000; Fernandes and Henriques‚ 1991). Agricultural soil is contaminated by heavy metals‚ has become a critical environmental concern due to their potential

has higher nutrients. Loam soil has better water holding capacity and nutrients compared to sand but less water holding capacity compared to clay (Kramer and Boyer‚ 1995). Compositions of soil play an important role in the germination mechanism of seeds of various plant species (Gulshan and Dasti‚ 2012). This is could be attributed to role soil particles plays in determining soil temperature‚ water holding capacity‚ organic matter etc which affect germination processes. In germination studies of most
