I need to solve some cause-and-effect problems. The problems are related to growth and development of plant. "Growth and Development" chapter is the first chapter in third level of high school (senior high school).

Show your answer with "Is the statement true?", "Is the reason true?" and "Are the statement and reason have cause-and-effect relationship?"

Problem 1

Anthurium should be sprayed with cytokinin hormone to prevent from wither easily.

Reason

Cytokinin hormone promotes/stimulates the growth of axillary buds that will produce lateral branching.

Problem 2

The stem of Avena sativa with the coleoptile is being cut, couldn't elongate.

Reason

Phytohormone that used for growing is only available at the end/peak of coleoptile.

My attempts to those problems are here:

Problem 1

What I know about cytokinin is when you soak the green leaves in the water with cytokinin, the green color will stay longer than without any soaking. I don't have any idea about the effect of cytokinin to flowers. I think I need to dig more knowledge about the hormone. I'm not sure with the reason too. Quick searching in Google Cytokinin and Wikipedia gives this:

... This promotes shoot growth, and restricts lateral branching.

The problem is my textbook clearly said that the cytokinin promotes the producing of lateral branching.

Because I couldn't prove the statement and reason, I couldn't give their relationship.

Problem 2

I think even the coleoptile is being cut, the flower must not easy to die. The phytohormone must be related with auxine hormone or other thing.

Because I couldn't prove the statement and reason, I couldn't give their relationship.

Any idea or answer is appreciated!

Feel free to edit my grammar. English is not my native language, but I could understand your post in English.
