Subject: RE: Magnolia grandiflora
Dear Javier,
Seeds of Magnolia grandiflora have underdeveloped embryos (i.e., morphological dormancy) and a high percentage of the embryos also have physiological dormancy. Thus, seeds have morphophysiological dormancy sensu Nikolaeva. I would give the seeds about 12 weeks of cold stratification -- put them on a moisture substrate at about 5 C -- and then move them to room temperatures. See page 385 of:
Baskin, C.C. and J. M. Baskin. 1998. Seeds: Ecology, biogeography, and evolution of dormancy and germination. Academic Press, San Diego. ISBN 0-12-080260-0
I hope this information helps.

I am a researcher in seed science and technology but appear to have missed your new book, Are there any reviews or publication notes available? Cost?
I am very much aware of the work of both of you from the 1960s onwards when I first entered the arena, and look forward to seeing the book.
I left the Department of Primary Industry and Fisheries in the NT Australia about 4 years ago to operate my own business based around the tropical areas after spending 25 years as the head of their seed science and technology program / seed lab / seed production section.

Dear Sir Madam:
I was performing an experiment involving sunflower achenes. My objective was to establish the LD50 of gamma rays and fast neutrons. The control germination rate was around 50 %. During the germination assays I found increases in the germination of 5 to 75 % when compared with the control and resulted in 15 % to 30 % in the number of the emerged plants in the field. Since radiation effects on biological materials are very complex, I guess that this phenomena may be produced by the destruction or alteration of sunflower germination inhibitors...what is your opinion?
Thank you very much.

Subject: fluridone
Dear seed biologists
I plan to use the abscisic acid antagonist FLURIDONE on fruits of Norway maple (Acer platanoides) and Siberian crabapple (Malus baccata) in order to suppress the ABA-peak in SEEDS normally occurring about August.
The Acer fruits are paintbrushed with 100 mg/L fluridone twice a week.
The apples are small (1 cm) but I dont know if paintbrushing will affect the SEEDS? shall I instead inject fluridone into the apple?
Maybe you have got a splendid idea, or experience with fluridone treatment on WOODY plants.
Hope to hear from some of you!

Subject: Re: marketing speaker is needed
Dear Dr. Fu,
The ideas, approaches, powers, and pathways in marketing seeds domestically and internationally are totally different between US and Canada. There are some solid 'technologies' involved in the marketing seeds of various crop species on the Canadian prairies where a well-established channel from the breeder's seed, to foundation seed, registered seed, and then certified seed has been used for marketing seeds to more than 150,000 large farmers with over 30 million acres of land. Levy from the seed, and the royalty and check-off from the marketed grain/seeds are returned to research institutes to support their in-depth and applied research programs relating to seed technologies. Having been involved in the seed channel in Canada by conducting breeding seeds with Research Center of Agricultural Canada and seed technology research at the research center for the last couple of years, I have accumulated sound knowledge in this area. Being a Chinese, I would be interested in providing informative lectures to our Chinese colleagues if it can be worked out.
Please let me know if you are interested in having a Chinese origin to do the task.

Subject: Coating corn seeds with a micronutrient
Dear Vatren,
Research in several places during the past several years (including Australia, Turkey, and South Asia) has shown that Zn-enrichment of cereal grains can result in significantly increased yields when the grain are planted to zinc-poor soils. A recent review covers some of this work (Welch, R.M. 1999. Importance of Seed Mineral Nutrient Reserves in Crop Growth and Development. In: Rengel, Z. (ed.), Mineral Nutrition of Crops. Fundamental Mechanisms and Implications. Food Products Press, New York. pp. 205-226). Much of the recent research being done in South Asia has not been published yet, but it is clear that pre-loading both rice and wheat grain with Zn via foliar sprays of the mother plant several times during reproductive growth can result in as much as 15-30% improvements in ultimate rice and wheat yields on significant numbers of farms in Bangladesh. Also, research from Australia clearly shows that zinc-loading of wheat grain via the mother plant is a much more effective technique compared to coating grain with zinc. It appears that zinc stored in the grain during development is much more bioavailable to the embryo during germination than is zinc coated on grain.
Sincerely,
Ross Welch

He wrote or co-wrote the Chenopdiaceae section of the "Flora of Australia" series and has contributed widely to this area in Australian taxonomy. His specialty is more in the herbaceous species relative to the woody representatives but he has been involved in the taxonomy of both. I did speak with him and mentioned he may be contacted.
I have some experience in the seed biology of Atriplex and Maireana species and know of others who have conducted more work in this area should you be interested. I also know a number of 'field taxonomists' should you want a more applied approach/information.

A colleague has brought me a tomato fruit she decided to chop up for lunch today and then discovered that the seeds inside had begun to germinate.

Can anyone suggest what specific conditions would have led to this sprouting? (Please don't laugh at the cress idea, my colleague is a forestry specialist.) . Thanks.

The situation you discribed might be vivipary tomato caused by the infection of microorganism. Here is one references for it:
Limberk and Udrychova (1972) Vivipary in fruits of tomoto plants infected with a mycoplasma disease --potato Witches' Broom. Phytopath. Z. 73:227-234.
We also found some soybean seeds (Williams 82' or Shi-shi) have the same situation. Seeds germinated in pods while they still are green. This is not heritable and is caused by the infection of Pseudomonas. We've performed Northern analysis, Western analysis, hormone assay and water potential assay for these vp seeds. We are now preparing for the manuscript.

Vivipary in tomatoes is not uncommon, although some varieties may show more vivipary than others. It occurs in the overripe fruit, when seeds have reached maturity and dormancy is lost gradually. The tomato fruit allows vivipary since the seeds do not desiccate in a moist environment. An ABA-deficient mutant (sitW) always shows vivipary when the fruit is left on the vine, around 50 dap. This indicates that ABA is involved in vivipary. Vivipary in wild-types occurs in older fruit, and this may explain why your colleague saw the phenomenon. Organically produced fruit should behave similar, but I can imagine that organically produced fruit is harvested older, and so the chance of detecting vivipary is higher.

Dear Janet,
this has to do with endogenous abscisic acid (ABA) concentrations in the fruit that usually prevents precocious seed germination in tomatoes (and probably generally in fruits/seeds).
During after harvest ripening ABA levels drop. There are also ABA deficient (natural mutants) tomato strain known, showing this peculiar phenomenon of seed germination inside fruits. Probably your tomato was either a chance mutation with low ABA levels, and due to longer storage that level dropped further allowing the seeds to germinate.

Hello Janet,
You can indeed observe vivipary germination in overripe fruits if tomato. This is a normal event in ABA-deficient mutants of tomato, but it can be observed also in wildtype tomato when the fruit is really much overripe, and where water relations has changed inside the fruit resulting from the softening of the fruit tissues. This has been observed in muskmelon and other species in which the seeds are kept or matured inside fleshy fruits.
Adding to that, you mention that the fruit was kept in the fridge where, the chilling conditions might be just the best to break dormancy of the tomato seeds in a wet state. This would also facilitate germination of the seeds inside the fruit.
All the best,
Renato
