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

Several studies show that music possesses properties that affect the growth rate of plants in different ways. These properties may be the wavelength of the music‚ its frequency or even its tempo. According to a study conducted by Margaret E. Collins and John E. K. Foreman‚ entitled The Effect of Sound on the growth rate of plants (2001)‚ plants growth is directly affected by sounds of varying frequencies. They observed that when plants are exposed to pure tones‚ it affects the growth of the plant

Abstract The purpose of this lab was to see if radiation has an effect on the cultivated radish seeds that we used. From the observed data that we collected‚ we were able to conclude that when seeds are exposed to radiation‚ it affects how they grow‚ if there is any growth at all. Introduction Radiation is an important environmental abiotic factor for plants‚ and one small section of the electromagnetic radiation spectrum‚ is called the Photosynthetically Active Radiation (PAR)‚ provides

Salinity on Seed Germination 1) Abstract: Poor seeding growth can be the result of soil salinity. A study was done to examine the influence of NaCl salinity treatment on the germination and seeding grow of vigna radiata using different NaCl concentration 0 (control) ‚ 0.25 ‚ 0.5 ‚ 1.0 ‚ 1.75 . A graph was used to analyze the data obtained from the study. Important differences among the treatment were indicated as a result of this study. The germination percentage of vigna radiata seed and radicle

PURPOSE The purpose of my experiment is to determine the effect of acid rain on seed germination. I chose this idea for a project because I have heard that acid rain is becoming a more prominent factor‚ around the world‚ due to pollution. I see reports of this in books and websites I ’ve visited‚ as well as news articles I have read.

The Tap Water allowed the radish seeds to germinate with in the first 48 hours. In the petri dish labeled tap water‚ 10 out of 10 seeds sprouted into plant growth as seen in Figure 5.1. The radish plant growth within the tap water petri dish grew so well it started to lift the lid off the dish. The results from the Acid Rain (50% vinegar solution) did not allow any radish seeds to germinate. There were never signs of seed germination while observing the seeds over a three week period. In the petri

created and the effects that they had on radish seeds were tested. This ultimately created a doseresponse experiment in which it was detectable whether or not radish seeds were a reliable bioassay for the toxicity of NaCl. The goal of this experiment was to determine a correlation between toxicity and seed germination/radicle length. Our data indicated that seed germination decreased as concentration increased‚ demonstrated by

Temperature Effects on Radish (Raphanus sativus) Root Development Abstract Several studies have been conducted to establish how temperature‚ seed germination‚ and root growth are related. Because temperature plays a main role in many growth processes‚ we decided to focus on how it affected root growth. Radish (Raphanus sativus) seeds were chosen due to their ability to produce a distinct bulbous tuber‚ and their relatively short growing time. Three test groups were placed under different temperature
