Survey Information.


List,

First let say me say thanks to all that took the
time to add entries to my little survey. Those
that added an entry received a copy of the data as
well, but as promised, I'm posting the results
here also. Respondents filled out a simple form
stating the name of the seed, city and
state/providence where the seed was grown and
three dates. 1. date seed germinated. 2. date
grower first noticed female flowers, and 3. date
flower opened.
I added sunrise and sunset values to each entry
for each date (hence the need for city and state).
Then I computed day length (in minutes). I also
computed the age of the plant at the time grower
first noticed female flowers. Below are some stats
on the numbers.

Number of entries:	40		
	
Germination:	
Minimum Day Length:	726
Maximum Day Length:	848
Percent Difference:	16.8%
Average Day Length	778.38
Note: Since most AG seeds are germinated indoors
under artificial conditions, Day length is of
little statistical value.	
	
First Female:	
Minimum Plant Age:	30
Maximum Plant Age:	73
Percent Difference:	143.3%
Average Age:		51.5
Minimum Day Length:	795
Maximum Day Length:	913
Percent Difference:	14.8%
Average Day Length:	855.05

Note:	Plant age is in days and day length is in
minutes.

As suspected, while there was a 143.3 percent
variance in the age of a plant to time of first
female flower, there was only a 14.8 percent
variance in day length. It appears that some
plants waited until the day length reached a
certain number of minutes before flowering
regardless of how old the plant was.

Like all survey data, we must accept that the
numbers may be skewed through recording and/or
reporting errors. However, I offer this
information to the list in the hopes that I will
add another bit of knowledge in our quest for the
giant pumpkin.

I would be willing to do this again if
sufficiently interesting questions were posed.
