Hi I have the question on my answer sheet

Give reasons for using seed propagaion as a method.

I have some but I need a few more, Below are the ones I have. Don't really need disadvantages
Ability to produce virus free plants
Quick planting process and lots at a time
Cheap because you don’t need specialised equipment

Hi Grant, is that Brighton UK? Just curious, it's not relevant to your question really, just that I used to live on the UK south coast.

Seed propagation would be necessary for annual plants. I'm not sure about specialized equipment, what are you thinking would be needed for other forms of propagation? I guess that depends if you are starting them in the garden (only the usual garden tools) or in in a greenhouse (containers, media, sanitation etc.). Seed propagation is used if you are trying to breed new plants. As far as viruses are concerned, some plant viruses are transmitted via seed so that would depend on the specific plant and specific virus.

For many annual plants, it might be the only practical way.

If you want to plant 50 acres of wheat, you aren't going to do it from stem or leaf cuttings. I don't even know if wheat WILL grow from cuttings, but even if they do, speed and cost would still favor seeds.

You can STORE seeds for many years, whereas cuttings require hundreds of times more space and constant attention.

What propagation methods ARE there, other than seeds and various kinds of cuttings? Spores, I guess. Tissue culture micro-propagation.

Maybe focus your answer on making distinctions: "propagating from seed is better than METHOD 2 because ...". In your class, what are the alternatives? Expensive research techniques? Traditional peasant methods?

Many educators will only agree with the answers that they taught. Don't just study the subject, study the teacher.

If they are focused on economic aspects, your answers need to say why seeds are cheaper.

If the course is centered on conservation, then the answer would be something like "you can preserve more varieties or genetic variation in a small space, economically, with seed banks).

If its about subsistence farming, there might be one set of answers. If it's about hobbyists and the latest daylily hybridization fashion, a different set.

>> Ability to produce virus free plants

I'm curious - can you get rid of viruses by growing from seed? I thought it took tissue culture micro-propagation and strong antibiotics? I might be wrong. Maybe that's only for potatoes.

Asking people who aren't taking the course might produce interesting, valid answers that the instructor won't like at all. At least be sure to word your answers in a way that the instructor will be sympathetic to.

(If you cite any references, be sure to cite at least one paper by your instructor. One that has not been refuted or withdrawn!)

Rick, it depends on the virus and the plant. Some viruses can be seed transmitted in some plants as I mentioned above.

There's even a whole book about them:

Curious about the answer sheet that you mention. Is this some kind of test you are taking at school?
