Seed Mutations in Atlantic Giant

Seed mutations of Atlantic Giant we can study them in a lab.

The vines of Atlantic giant are monsters occupying 2500 sq.ft. or more if allowed to grow freely without pruning. Seed mutations could be studied in the lab. At present no mutations of the seed are known. Enzyme mutations know in the growing plant will be placed under seedlings.

Indiana Biolab is looking but not planning any major effort to find seed mutations in C. maxima. The seed storage proteins might be a fertile place to look for mutants.

Re: germination time (pumpkins@mallorn.com, Thu 09:52) To: Indbio

Pumpkin flower, My 906.5 was also the first to germinate. It may have something to do with the thinner seed walls on a white seed. Sanding my tan seeds aggressively has helped them without a doubt but they are still slower it seems. Just a general observation not a hard and fast rule.

Cracked AG Seeds (indbio@disknet.com, Thu 13:51) To: Indbio

Eddleman

One often reads of a beginner worried that he got cracked AG seeds. One often reads mentors assuring everyone that cracks seem to have no effect on germination.

When you examine a tan AG seed or the the hull discarded by a seedling under 5X to 15X magnification, the answer is easily seen. Recall from my seed diagram http://www.disknet.com/indiana_biolab/seed2.gif that the tan colored layer is merely tiny fibers standing on end. The cracks are merely shrinkage cracks caused by drying of the fibers and have no effect on the the drying of the seed or oxidation of the storage oils in the cotyledons. The cracks are merely spaces between normal fibers. Below such cracks, Layers B (compact pith), Layer C (resin saturated cells(?), Layer D (cushioning pith), and the two membranes are all intact.

A wet hull discarded by a seedling is an excellent specimen to examine to see these fibers. I can't recall ever seeing a seed so complex as the AG seed. -- Harold Eddleman Ph.D. Microbiologist. mailto:indbio@disknet.com Location: Palmyra IN USA; 36 kilometers west of Louisville, Kentucky http://www.disknet.com/indiana_biolab/pk.htm


seed cross section (jim_kunde@adc.com, 04/28/99 15:23) To: Indbio

harold

at my job i do a lot of cross sectioning. i am going to try a seed or two to see what happens i also have plenty of cameras in the microscopes and all are digital. i'll send you some of the pictures if you want copies. let me know.
