Tobbaco (Nicotiana sylvestris) phyllotaxy This timelapse of N. sylvestris was recorded over 1.5 weeks. Note the clockwise alternate phyllotaxy (leaf growth/arrangement) of this plant. The leaves grow opposite to each other. This pattern does not change as the plant matures.

LotusVideo2.wmv Lotus Kolam is expected to be represented for Lotus petals, and Phyllotaxy（Leafs/petal arrangement) of the leaf number of N in a circle and the repeated turning number of L, and then Divergence (Angle between 1st-2nd Ｐｅｔａｌ 360 x L/N deg. arc. ) of the Phyllotaxy women use in Kolam, are approximate values. Here Kolam is drawn on N=8, M=5 and L=5 of (1,2,4,5,3,1) and then GCD(N,L)=1 as the loop number (1 means as as the unicursal. We find the Arrangement of leafs/petals, and Phyllotaxy of 5/8 and Divergence of 360x5/8 deg arc. The equal to 21/55 or the larger Fibonacci number of Phyllotaxy makes Golden ratio (0.6181) and Golden angle (360*0.6181=137.5deg), in the case of which leafs or petals are in non-repeating/infinitive periodic arrangement. The actual arrangement of Lotus petals has this condition.
Sunflower Tower Outdoor Installation bamboo architecture based on phyllotaxy (Golden Ratio). The music is also based on the Golden Ratio. This structure is very strong against earthquake. recorded: 3rd December 2006 (c)2006 Akio Hizume
Exercises in Grapevine Breeding and Genetics Dwarves, Worms, *** Change, and Bunch Rot: Exercises in Grapevine Breeding and Genetics Peter Cousins, Geneticist, USDA-ARS Grape Genetic Reources Unit, Geneva, NY Cornell University Department of Horticulture seminar series, Feb. 27, 2012 Take a grapevine, divide it into its essential parts, then pick, choose, and reassemble to develop new varieties and selections for grape growers and wine makers in New York, across the country, and around the world! Peter Cousins will discuss USDA ARS research in grape rootstock breeding, mutant dwarves, worm proofing, precocious flowering and remontant grapevines, gamma radiation, *** change--and phyllotaxy!
