how to cross two plants?

Question

i'm doing a science fair in school, and my partner and i chose the effect of genes on skin color. We decided to use plants, we turned in out forms then we realized we didn't know how to cross two plants...lol...we want to use a white rose and red rose..if you have any idea on how to get the two plants to reproduce, it will be really helpful!

i have to have the results by early or mid jan.

Answer 1

Depending upon the time frame you have, the first answer seems wise. You need a plant that blooms simply, pollinates easily, and grows quickly. Beans are actually a really good choice.

Pollination is easy. You need at leasat two plants of differing varieties, since your project incorporates that. I would suggest more than one as a safety net. As one variety blooms, collect pollen from the stamens using a q-tip. As the other plant blooms, you'll take your pollen and place it on the stigma of the carpal. The carpal will be ready for pollen when you see a bit of a sticky substance on it. If it is no longer sticky, you've missed your window of time.

If you choose plants that can self-pollinate, you will need to be sure to clip the stamens on the flowers you are pollinating. If it does not self pollinate, it won't be a problem at all.

Remember that you are growing from seed, so the time frame will be longer. It's possible to grow African Violets more quickly than some other flowers, but you have to be really good about their environment. They cannot self pollinate, so that's a bonus.

Beans are one of the fastest, easiest plants to grow, though. Just not very impressive in the blossom area.

Answer 2

First of all I don't think that white rose and red rose are a very good choice. They take too long to grow and as a result you will not have offspring available in the next year.

I would pick a faster growing plant... perhaps bean or why not the pea... The both grow reasonable quickly but I don't know how far off the science fair is so it might still be a problem.

To cross a plant what you do is take the pollen from one plant (sometimes this is done using a feather or a Q-tip and rubbing it on the Anthers) and place the pollen on the Stigma of the other plant. Make sure before you do this that the second plant has it's anthers removed by cutting the stamen before the pollen matures. Look at a diagram of a flower to see which part is which :-)

Answer 3

Take the pollen from one plant and rub it to the female part of the other plant which is called the stigma, after the flower will wither then there will be round green balls which are called seed pods after the seed pod turn ripe the seed pod starts to split open then after the wind blows the seeds the seeds get barried over the years and they start a new plant.

Answer 4

Then you'd better use something like FastPlants, which are small plants especially bred for genetic research. If you had two blooming rose plants right now, you wouldn't have mature seed in January. Even Fast Plants would be cutting it close

Answer 5

Well, you could go up to several Acers and tell them that they are not very funny because they were not Quercus!
That should make the grove of Acers angry.

While some Acers are are sweet not all Querus are funny.

Answer 6

you need something that will grow faster. my dad once planted his tomatoes too close to his peppers. what he got was a red pepper with the pulp of a tomatoe. they were very good to eat. we called them pamatoes. this may give you a start. good luck
