The past few posts have been incredibly informative and everyone has answered my questions and then some! My trees would probably have all died long ago if it wasn't for you all on this site, thanks again everyone.

JRB your link is interesting. I wrote a post some weeks back taken word for word from the same Purdue website. My post was concerning the spraying of arsenic to induce peel injury supposedly causing ethylene for the early ripening of grapefruit. Dr. Manners upon reading it pointed out that the Purdue web site was in error, as what the site claimed could not possible be true. He was going to write the University advising them of the error, whether he did or not I cannot say. However, this is not to disparage your link, as my guess Purdue's arsenic claim was probably a rare mistake. Anyway, I agree with you that generally Purdue offerers excellent information. You seem interested in the biology of the citrus family, so I would recommend a REALLY EXCELLENT book, packed full of more information than any single book I have read on citrus. The name of the book is "Biology Of Citrus" by P. Spegel-Roy and E.F. Goldschmidt. A really excellent text. - Millet (1,253-)

Dr. Manners wrote in the above link: "The Purdue folks are apparently mistaken here. Ethylene would promote the fruit falling from the tree, and perhaps early color formation, but should have no effect at all on internal quality, and certainly, not in reduced acid formation early in the season. The mode of action I described is, as far as I know, completely accepted by all citrus physiologists. "

On page 2 of this thread there is a post from Meyerlemon, 1 year ago.
He asked if kumquat hybrids come true from seed and he was unanswered.
I am curious about this as well.
Anyone...

Millet, the link was actually mine. I do have an interest in citrus biology; many years ago I got a BS in BS and my interest in biology has not waned. Thanks for the book recommendation, I have put it on my wish list.

fofoca, sorry I got the names mixed up. I guarantee you will really appreciate the book. - Millet (1,252-)

So far I haven't purchased any books on citrus but, when I do, I will buy the one you mentioned first.

I never had a single biology class growing up. I was more interested in math, physics, chemisty, and engineering. However, when I wanted to start growing a few container citrus trees a couple years ago I had questions I couldn't answer without learning something about citrus biology so I started looking on the web for information.

My favorite web site for learning about citrus biology has been an on-line version of the the book "The Citrus Industry" from the University of California. I have found it to be extremely interesting and informative even though it is somewhat dated. I have now read most of it and have enjoyed it very much. Only certain chapters are available online because the web site says the other chapters are too dated to put online and would be misleading.

The URL is

http://lib.ucr.edu/agnic/webber/index.htm

Volume II, chapters 4 and 5 have a lot of information on embryony and ploidy. I knew nothing about this subject before I read this on-line book and it answered a lot of questions I had.

The direct URLs to those two chapters are

http://lib.ucr.edu/agnic/webber/Vol2/Chapter2_4.htm
http://lib.ucr.edu/agnic/webber/Vol2/Chapter2_5.htm

Incidentally, there are many broken links to figures and tables in this book but all broken links seem to be due to the same issue and are easy to work around although annoying. There is an upper case/lower case problem in the links. For example, if you click on fig. 4-9 your browser will go to

http://lib.ucr.edu/agnic/webber/Vol2/Images/Fig4_9.JPG

which does not exist. If you change "JPG" to "jpg" you will find figure 4-9 like this

http://lib.ucr.edu/agnic/webber/Vol2/Images/Fig4_9.jpg

Many of the table links call intermediate html pages which have the same problem. For example, if you click on table 4-1 you go to this URL

http://lib.ucr.edu/agnic/webber/Vol2/Images/Table4_1.htm

which shows a blank page. Assuming you are running on a windows system, if you right click over the blank rectangle and click on properties you will see it is trying to link to

http://lib.ucr.edu/agnic/webber/Vol2/Images/Table4_1.JPG

If you change the address line in your browser to

http://lib.ucr.edu/agnic/webber/Vol2/Images/Table4_1.jpg

you will see the table you wanted. Some of the intermediate html pages refer to more than one figure. If you click on table 4-2 you will see two blank rectangles. If you look at properties for each of those rectangles you will see links to

http://lib.ucr.edu/agnic/webber/Vol2/Images/Table4_2a.JPG
http://lib.ucr.edu/agnic/webber/Vol2/Images/Table4_2b.JPG

which you change to

http://lib.ucr.edu/agnic/webber/Vol2/Images/Table4_2a.jpg
http://lib.ucr.edu/agnic/webber/Vol2/Images/Table4_2b.jpg

I suspect the html version of this book might have been developed on a windows system, which is case insensitive, and then was moved to a Linux or Unix system, which is case sensitive.

If all else fails, the data files are located here.

You can step through the directory and find what you want.

Thanks for all the time and effort you put into explaining how to best use the computer installment of The Citrus Industry. This should help our membership to better read it. I purchased all four Volumes of The Citrus Industry some years back. Volumes 1 & 2 from Abe's Rare Books. I think I paid a little over $100.00 for Volume 1 & 2, Volumes 3 & 4 were purchased from a company called Florida Science Source, Inc. Florida Science Source, has a very wide selection of citrus books. - Millet (1,252-)

Thanks, jrb, I definitely prefer the version you recommended to the one Millet bought!
Thank you for all the care you've taken to debug and explain the links problem. I'll definitely give that a look!

What orange matures quickest from seed?

fofoca, actually they are exactly the very same versions word for word. Only one version of Volumes 1 & 2 were ever printed. Volumes 3 & 4 were-printed years later. Volumes 3 & 4 are not revised versions of 1 & 2, they cover entirely differtnt citrus topics. Volumes 3 & 4 are in themselves stand alone books. - Millet (1,251-)

I think fofoca was referring to the cost ----- $100 vs. free. The online versions are only a few selected chapters of the first two volumes but there is lots of useful information there for a beginner like me.

jrb, guess I was a bit slow to getting that one. Thanks for bring me up to speed. BTW if our membership is not familiar with Abe Books, it is a good place to find rare, out of print books, as well as current printings. - Millet (1,251-)

Yes, jrb is correct, I am a cheapskate!

I found a seed in what was labled a Murcott mandarin (no other seeds found). I've decided to plant it. What are my odds of getting true to type and what sort of maturity period am I facing?
