DISCUSSION
1. Potted plants B, C, D have nodules. But plants in pot C has more nodules compared with other potted plants. This is because, under nitrogen-limiting conditions, capable plants form a symbiotic relationship with a host-specific strain of bacteria known as rhizobia. Soil type C containing more nitrates than other soil types. Nodulation occurs when plants need additional nitrogen. Beans send flavonoids into the soil through their root systems. Rhizobia bacteria in the soil sense the flavonoids and send a signal called LCO back to the plant. The plant responds with root hair curling where the Rhizobia enter the plant and nodules are formed around them. Brown/Green colour of the nodules do not fix Nitrogen for the plant.
2. Most of the plant have an average wet weight of whole plant. In the case for plants in pot C, the roots longer than the other plant in other pots. The grow of nodules also have an effect on the length of the roots.
3. We let the plant dry outside the lab. After 3 days, we let the plant dry outside the lab. We weight it to get the dry weight. The result show the decreasing of the plant weight.
4. The result show that the neutral pH value show that the higher germination than the acid pH value.
5. The texture also affected to the germination of the snake bean. The loam and loamy sand type of soil has nothing growth on it.

The lines on the textural triangulation figure is incorrect.
ReplyDeleteThe number of leaves is incorrect. I don't think in seedling stages you will have that much leaves.
ReplyDeleteThere is not introduction of where each soil were taken.
Guessing game?
Discussion part for this report is out of place.
ReplyDeleteIsn't this discussion for results on 3rd/4thweek instead?
