Two lenses arrived today! First was a stunning Schneider Kreuzach Edixa Xenon 135mm f3.5 orgasmatron...... OK, I added the last bit but it is stunning! I cannot wait to test it! The second arrived shortly after and this one I did test. I took it out for a walk round the village and the pictures appeared so sharp that I cut myself when I was viewing them. This baby, and possibly my new favourite, is a mamiya sekor 50mm f2! I am in love!

Grocery bargains

I just bought 10 ears of corn for $1.00 and also a seedless watermelon for $1.00.

Interesting question. Where do they get the seeds when they want to plant seedless watermelons?

from watermelons that made seeds without the gene for creating seed

like parents can makes child that are sterile. Same thing.

Or cuttings.

Don't tell Tess. She's always joking about stealing someone's cute kid.

It's kinda like a mule, the sterile offspring of a male donkey and a female horse.

I believe they are hybrids between parents with different numbers of chromosomes, which result in a viable but sterile plant. You need to have fertile watermelon plants around to produce pollen to get pollinate the blooms of the seedless variety so they produce fruit, inside which it attempts to produce seed but isn't quite up to the task.

Have you never seen a watermelon helmet? That's the most fun you can have with a watermelon. Plus you'll blend in with Saskatchewan Roughriders fans, and they know how to throw a good shindig.

Yeah they call it cloning.

Two plants i can think of immediately that are not grown from seeds: banana and apple.

And within the USA dandelions reproduce more or less by cloning = there are no male & female plants.

Pineapple too, I think... I'm sure I saw a TV programme recently where the pineapple plant was grown from a cutting (I may be getting confused, though).

So... how do plants like these propagate, I wonder?? (apologies for the break from thread purpose - I think we're used to it here by now, though )...

Vegetatively, as in cutting off a chunk and sticking it in moist soil so the chunk grows into a new plant. Some plants can be propagated by taking cuttings of roots, some you can have success by chopping off an above ground growing tip and convincing it to grow roots and eventually become a stand alone plant of its own. Next willow you see, cut off a handful of ~10" tips from the ends of the branches. Stick the cut off end in a glass of ~5" of water and watch the roots grow (it will take a few weeks, so have a good book on standby).

Mass propagation can be done via tissue cultures where, in labs, they can grow new plants efficiently from very small parts of the mother plant. It can be a problem when your entire crop is genetically identical though, the wrong disease could potentially wipe out all your bananas. We're trading genetic diversity for a fruit that's a sure thing.

I don't know much about apples, but I don't think any apple varieties come true to their parents via seed. In other words, if you want a tree to produce Crispins, you'll have to propagate it from another Crispin vegetatively. You can make more apple trees via seeds, but they might end up even more horrid tasting than the apple you started with (or possibly better).
