Abstract The Seeds of Mung bean‚ wheat‚ and silver beet were tested in environments of differing salinities to note down if high salinity environments were worse for the seeds. It was found that generally lower concentrations were better for germination then higher concentrations. Despite this‚ the hypothesis was not completely supported as in wheat and silver beet the second concentration had a higher rate of germination than the control and in all instances the highest concentration had a higher

development. This lab uses lima beans in order to determine whether they were viable or not. If a bean is viable‚ it means that it is alive: able to grow and develop. The two ways to find out whether a bean is viable or not‚ are a tetrazolium test and germination test. Tetrazolium is a chemical that turns red in the presence of hydrogen ions. All living organisms release hydrogen ions every day and therefore‚ it was possible to see whether the lima beans were viable or not using tetrazolium. This is a result

Introduction: The world’s total forest area is just over 4 billion hectares‚ which corresponds to an average of 0.6 ha per capita (Figure 1). The five most forest-rich countries (the Russian Federation‚ Brazil‚ Canada‚ the United States of America and China) account for more than half of the total forest area. Deforestation – mainly the conversion of tropical forest to agricultural land – shows signs of decreasing in several countries. Around 13 million hectares of forest were converted to

and growth (in cm)‚ germination‚ and survival rate was measured. Results showed that at the right level of radiation level (10 kR)‚ radiation have a positive effect on the plant growth and has the same germination and survival rate from the control set up. The 30 kR set up and 50 kR set up are relatively smaller in growth than the control set up. Thus‚ increasing the radiation level above 10 kr corn inhibits its growth in terms of height and decreases the percent germination ofcorn (Zea mays L.)

problem by producing sufficient quantities of food products by efficiently modifying plants to generate identically cloned plant material in the form of artificial seeds (Bewley‚ 1997). To accomplish the end goal of formulating artificial seeds‚ the somatic embryo of the plant must behave similarly to the zygotic embryo that exists in natural seeds (Martinez‚ 1986). Different factors have the potential to stimulate somatic embryos into zygotic embryos (Wu‚ 1994). The purpose of this experiment is to test

The Effects of Household Detergent on Germination and Biomass Production of Pinto Beans and Radishes Introduction and Background: Plants are a diverse kingdom that gives vital sources of food‚ energy‚ and oxygen to sustain life on the planet. Plant classification is divided into four major groups including mosses and liverworts‚ ferns‚ conifers‚ and flowering plants. Plants we most commonly identify ourselves with is edible fruits and vegetables. There are a variety of types of vegetables from

The minimum amount of lead (0 mg/gm) was found in plant treated in 0 % concentration of lead acetate and maximum amount of lead (0.0011 mg/gm) was found in plant treated in (0.6%) concentration of lead acetate. The percentage germination for control‚ 0.2‚ 0.4‚ 0.6 percent lead acetate treated seedling was 89%‚ 88%‚ 86.66% and 83% respectively. The length of shoot was found much less in plant treated in 0.6% concentration of lead acetate (10 cm)‚ as compared to the length of shoot

The Effect of Water on Germination and Plant Growth in Marigolds Question: How does the amount of water given to a plant affect how much it grows? Hypothesis: If I give water to a marigold seed then it will germinate and the plant will grow more than a seed not given water. Independent Variable (IV): the amount of water given a seed/plant Dependent Variable (DV): the amount of plant growth Control Group: The group of plants given water Experimental Group: The group of plants given no water

Lastly‚ the terrestrial chamber contains a small plant or seed as well as soil and/or fertilizer or mulch. The purpose of our making the eco-columns is to observe the effect of the manipulated variable on the dependent variable; more specifically‚ what is the effect of fertilizer in the terrestrial chamber on
