Abstract
Drought is a dangerous problem for humanity and for nature that global warming causes. There are insufficient researches about how to minimize the repercussions of drought so a research question formed, which is: ‘Is Portulaca oleracea effective at decreasing the consequences of global warming?’ and an experiment decided to make to observe the validity of this question. Portulaca oleracea used in the experiment instead of another plant because it has long living periods at high temperatures and it can survive long times without having water. Control group for Portulaca oleracea is Spinacia olecacea. Portulaca oleracea is a C4 plant, Spinacia olecacea is a C3 plant. C4 plants show remarkable adaptations to high temperatures and water stress. In the experiment three of the flowerpots contained Portulaca oleracea seeds where the other three flowerpots contained Spinacia olecacea seeds. The flowerpots watered with 0.1 kilograms of water daily until they became one week old. After the plants developed their leaves, 0.2 kilogram of water added to each of the flowerpot which made them to become 1.075 kilograms. The method of this experiment was equalizing the masses of the flowerpots to 1.075 kilograms with adding water by weighing them daily. The process made to find out the daily amount of consummated water by plants while doing their photosynthesis. All the flowerpots should be weighted every day to have a continuous data. This process made for 15 days. After finishing the experiment T-Test made to compare the two sets of data. As the results showed, t value was bigger than 3.6739 (4.3753>3.6739) which supported the hypothesis. So, Portulaca oleracea uses less water than Spinacia olecacea. Using Portulaca oleracea in droughty places can be a solution for both the water and nutrient problem.
