Temperature, pH, and Salinity as Limiting Factors Affecting Growth, Development, and Survival of Rainbow Fishes and Corn Seeds
Brendalyn R. Basilan
INTRODUCTION Environment should be suitable for the organisms to stay fit and survive. These environmental factors should meet the minimum and maximum criteria of what life requirements to satisfy the organisms’ state of existence. The environmental influences that coerce the increase of populations and have the ability to object their capability to avail the full biological potential under optimal conditions are so called limiting factors. (Jadap et.al.) It can be distinguished into two categories: physical factors and biological (biotic) factors. Physical factors include temperature, salinity, …show more content…
However, on the treatment 1 and 2, comparisons can be clearly seen. The rainbow fishes in treatment 1 having 10 – 15 ˚C shows that from fast opercular movement to slow and their swimming speed became slow in movement, too. Through observing the behavior of these fishes, one can conclude that they have meet the optimal condition where they no longer can continue their pace of living and far too different from the normal temperature they supposedly should fit. Rainbow fishes in treatment 2 having 30 – 35 ˚C, although they show no aggressive behaviors, they slowly adopt on the environment in the long …show more content…
2 Percentage of corn seeds that completed germination in a seven-day period
The pH 5.0 or 4.0 simulated acid rain had the lowest percentage of total corn seeds germinated within the seven-day period. The rest of the pH values portray slow metabolism of corn seeds which show shorter roots. The preferable pH that a corn seed will germinate is the pH having 6.0.
Salinity
The result on salinity was taken from the research paper of Jadap et al., entitled Temperature, pH, and Salinity as Limiting Factors Affecting Growth, Development, and Survival of different organisms. To compensate the expected results, the data taken shows the root and shoot length, as well as the ratio. Fig 3. Germination percentage of the corn seeds with the different salinity treatment Figure 3 more likely shows that the control and 2.5 ppt of salinity treatment are those whose germination of seeds doesn’t prevent its capability to grow. Therefore, corn seeds germinate on the pH that is closer to the neutral or on lower salinity concentrations. Salinity affects the seedling growth of plants by slowing mobilization of reserve foods, suspending the cell division, enlargement and injuring hypocotyls. Furthermore salt tolerance among plant species varies and seed quality. And also salt concentration maintained reduces seed viability and therefore reduces germinability are brought about by the negative osmotic potential of
