More and More on Color

October 23, 2016  08:00

We have continued to examine the spectrum of absorbance of various flowers and we show three below.

What is interesting is that the "blue" one, caryopteris has two strong dips with a block in the green yellow band. It is worth loking at these in detail.

We have been doing a lot of spectrophotometry on the pigments. Below is Indian Giver.

Note the peak absorption at 530 nm somewhat in the green spectrum. Remember that white light hits the flower petal, passes through the colored cells and then reflects back out the same way. If the cell absorbs green and does not absorb red then we get red. Here we see not much red and some on the blue end with a peak in green.

Below is Halloween Cat:

Here the blues absorb a bit more. I will write up the technique. You have to dilute the anthocyanin to an optimum level, requires matching peaks.

The Beginning

January 3, 2016  08:00

Well, Happy New Year! We have started this year by sorting, analyzing, and staging our seed for this coming season. We did 526 crosses, with 286 mature pods for a 54.4% yield. This is one of our better yields. The overall results are as follows:

The above is the number of viable seeds per day of cross. What is of interest is cross correlating this with maximum daily temperature. For example the drop in mid July is we believe due to excess temperature.

The above is the seed distribution. Namely this is the distribution of seeds per pod and its cumulative. It clearly is not Gaussian as has been the case with all previous years. The average is about 12 seeds per pod but we do have extreme outliers.

The above is the plot of the number of seed and time to mature. Namely the time between cross and seed collection. Note we have some very short seed times and some very long. The bulk is between 42 to 65 days.
