Part B of my Experiment [aka: HOW PLANTS WILL DIEE!!!]

[Note: All allelopathy & allelopathic traits mentioned in this entry are negative, unless mentioned otherwise. Hehe.]

For Part B of my experiment, I want to record the effects of allelochemicals on different types of plants. I have researched allelopathic plants, and I believe that I should plant sweet potatoes because apparently they are not hard to grow: "In fact, the question is not how to grow sweet potatoes, it's rather how to stop sweet potato vines from taking over the whole garden!" and "...sweet potatoes grow with little water and fertiliser." - Source: http://www.tropicalpermaculture.com/growing-sweet-potatoes.html

Well, that's certainly convenient. Whoo! 8D

Furthermore, all I need to grow them are some cuttings about 30cm long. They should be quite easy to obtain from a gardening place like Flower Power, or something.

However, they should take about two and a half to three months to mature in warm weather, longer in cooler weather - and that period is from planting to maturity. Obviously, since I only have 3 months and I still need time to write up my results, conclusion, discussion, etc. I will have to modify my experiment so that maybe I do not start right from the planting of the sweet potatoes, or I will only record my observations for two and a half months.

I think that I would rather record my observations for two and a half months.

Anyway, as mentioned in my previous post:
"I think I want a range of different plants - I researched modern classifications of plants, and one method of classifying them was by the way the plants took in water - whether they get water from the ground through their roots or simply absorb water through their surfaces (leaves, etc.)."

But I want a range of different plants based on their different structures, so I can see the effects of allelochemicals on a variety of plants. Because of this, I think that I should plant two sweet potatoes - one far Part A, with one vascular plant and one non-vascular plant; and the second for Part B, with different types of plants planted around it. My initial idea for "different types of plants" was: a flowering plant, a cactus and a leafy plant. But I'm not sure if they sufficiently cover a wide range of general plants.

Anyhow, I will plant these around the sweet potato, and observe the effect of the allelochemicals on them, along with taking photos just like Part A of my experiment.

On a different subject, according to my research, not all allelochemicals affect every plant the same way.
"The black walnut (Juglans Ingra) produces the allelochemical juglone, which affects some species greatly while others not at all." - Source: http://en.wikipedia.org/wiki/Allelopathy

In this particular case with the sweet potatoes:
"The allelopathic substances in sweet potato were identified as coumarin, trans-cinnamic acid, o-coumaric acid, p-coumaric acid and chlorogenic acid." - Source: http://www.cababstractsplus.org/abstracts/Abstract.aspx?AcNo=20043010129
