 +<html><a href="http://www.flickr.com/photos/foam/5603665460/" title="Picture 18 by _foam, on Flickr"><img src="http://farm5.static.flickr.com/4106/5603665460_73b35efe55.jpg" width="75" height="50" alt="Picture 18"></a></html>---Why botany, a potentially fascinating subject dealing with plants, living  
 +and extinct, their uses, classification, anatomy, physiology, geographical  
 +distribution, should have been from the beginning reduced to** a dull  
 +taxonomy, an endless Latin dirge**, in which progress is measured more  
 +by the number of corpses cataloged than by the number of blossoms  
 +cherished, is perhaps the greatest mystery in the study of plant life. Pg 104  
 + 
 +**The pollen of most plants has a highly inflammable character**; when  
 +thrown on a red-hot surface it will ignite as quickly as gunpowder.  
 +Artificial lightning was formerly produced on the theatrical stage by  
 +throwing the pollen grains of the Lycopodium or club mosses onto a hot  
 +shovel. In many plants the pollen diffuses an odor bearing the most  
 +striking resemblance to the seminal emission of animals and man.  
 +The spermatozoa of certain mosses carried in the morning dew in search of females, is guided by its taste for malic acid toward the delicate cups at the bottom of  
 +which lie moss eggs to be fertilized. **The spermatozoa of ferns**, on the  
 +other hand, liking sugar, **find their females in pools of sweetened water**. Pg 107 
 + 
 +---For years Goethe had been distressed by the limitations involved in a merely analytical and  
 +intellectual approach to the plant world, typified by **the cataloging mind  
 +of the eighteenth century**, and of a theory of physics, then triumphant,  
 +which submitted the world to blind laws of mechanics, to a "jeu de  
 +rouages et de ressorts sans vie."

Did not flowers and  
 +trees finally consume man and, by combining his remains together with raw earth, water, air, and sunlight, transform and transmute human bodies into the most glorious forms and  
 +colors?

 +<a href="http://www.flickr.com/photos/foam/5603081267/" title="Picture 14 by _foam, on Flickr"><img src="http://farm5.static.flickr.com/4097/5603081267_92481df2e3_s.jpg" width="50" height="50" alt="Picture 14"></a>---In 1950 T. C. Singh, head of the department of botany at Annamalai University , 
 +began wondering whether sound, properly prescribed, could spur field crops to greater yields. From 1960 to 1963 he piped the "Charukesi raga" on a **gramophone via a loud-  
 +speaker to paddy rice growing in  
 +the fields** of seven villages on the Bay of Bengal, and got harvests ranging consistently from  
 +25 to 60 percent higher than the regional average. He also was able  
 +musically to provoke peanuts and chewing tobacco into producing nearly  
 +50 percent more than normal. Singh further reported that merely by  
 +dancing the "Bharata-Natyam," India's most ancient dance style, with-  
 +out musical accompaniment and executed by **girls without trinkets on their ankles, the growth of Michaelmas daisies, marigolds, and petunias  
 +was very much accelerated**, causing them to flower as much as a fort-  
 +night earlier than controls, presumably because of the rhythm of the  
 +footwork transmitted through the earth.  
 + 
 +---  
 +In the mid-1960s two researchers at Canada's University of Ottawa, Mary  
 +Measures and Pearl Weinberger were conversant that ultrasonic frequencies markedly affect the germination and growth of  
 +barley, sunflower, spruce, Jack pine, Siberian pea tree, and other seeds  
 +and seedlings However, the very  
 +frequencies which stimulated some plant species inhibited others. They wondered whether specific audible frequencies in  
 +the sonic range would be as effective as music in enhancing the growth  
 +of wheat.  
 +In a series of experiments lasting more than four years, the two  
 +biologists exposed the grains and seedlings of spring Marquis and winter  
 +Rideau wheat to high-frequency vibrations. They found that, depending  
 +on how long the wheat seeds had been vernalized, **the plants responded  
 +best to a frequency of 5,000 cycles a second**.  
 + 
 +---1973 Dr. Weinberger said **basic farm equipment of the future will include an oscillator** for production  
 +of sound waves and a speaker." He set up large-scale tests to determine the practicability of their idea.  
 +they discovered that experimental "pink" noise, which, at 20 to 20,000 cycles per second and 100 decibels, sounds to the ear about the **same as the noise received 100 feet  
 +away from a 727 jet plane** about to take off, caused turnips to sprout much faster than those left silently in the ground. Pg 152 
 + 
 +Allotting one chamber for a control group, Mrs. Dorothy Retallack, a Danish professional organist and mezzo soprano in 1968 used the  
 +same plants, as in the first experiment,  
 +setting them in identical soil and affording them equal amounts of water  
 +on schedule. Trying to pinpoint the musical note most conducive to  
 +survival, each day she tried an **F note, played unremittingly for eight  
 +hours in one chamber** and three hours intermittently in another. In the  
 +first chamber her plants were **stone dead within two weeks**. In the  
 +second ·chamber, the plants were much healthier than controls left in  
 +silence
  
 +---The cucurbits were hardly indifferent to the two musical forms: those 
 +exposed to Haydn, Beethoven, Brahms, Schubert, and other eighteenth- 
 +and nineteenth-century European scores g**rew toward the transistor 
 +radio**, one of them even twining itself lovingly around it. The other 
 +squashes grew away from the rock broadcasts and even tried to climb 
 +the slippery walls of their glass cage. Pg 154
 +The plants gave positive evidence of **liking Bach, since they leaned
 +an unprecedented thirty-five degrees toward the preludes**. But even this 
 +affirmation was far exceeded by their reaction to Shankar: in their 
 +straining to reach the source of the classical Indian music they bent 
 +more than halfway to the horizontal, at angles in excess of sixty degrees, 
 +**the nearest one almost embracing the speaker**. 
  
 +--Jazz caused her a real surprise. When her plants heard recordings as 
 +varied as Duke Ellington's "Soul Call" and two discs by Louis Arm- 
 +strong, 55 percent of the plants leaned fifteen to twenty degrees toward 
 +the speaker, and growth was more abundant than in the silent chamber. Pg 156
