Biology Coursework Skill I+J Benefits and implications of improving plant productivity Tamryn Renwick To increase plant productivity we can manipulate the environment, or more importantly we can improve the plants. There are many different ways that plant productivity can be improved, for example one option is to keep them in ideal, controlled environments such as glass houses and poly-tunnels. In these conditions, light intensity, temperature, CO2 concentration, moisture, etc are adjusted to suit a particular crop (2). But one major problem with this method of crop production is that costs are very high and there is not always a big enough profit. Another process that can be used to increase plant productivity is breeding programmes based on hybridisation. This process has many disadvantages though, such as, there is the transfer of few desirable genes also accompanied by the uncontrollable transfer of an additional 1000- 10 000 genes (1), the process takes 10-15 years...
