Bear Paw Petroglyphs and the Prehistoric Martis Complex
Autor: Willis A. Gortner
Publikováno v: North American Archaeologist. 15:69-76
People of the Martis Complex occupied lands adjoining the north-central Sierra Nevada from approximately 2000 B.C. to 500 A.D. They left their rock art on 100 or more rock outcroppings. The appearance of glyphs clearly resembling a bear paw or bear t

Evidence for a Prehistoric Trail Map in the Sierra Nevada. III. A Fourth 'Glyph Map' and a Composite of the Trails
Autor: Willis A. Gortner
Publikováno v: North American Archaeologist. 11:99-106
Two earlier reports indicated that three unusual carvings at a single petroglyph panel in the Sierra Nevada (CA-PLA-571) probably represented maps of hunting trails used by people of the Mart is Complex. In this article, a fourth wavy glyph appears t

Evidence for a Prehistoric Petroglyph Trail Map in the Sierra Nevada. II. Two Additional 'Glyph Maps'
Autor: Willis A. Gortner
Publikováno v: North American Archaeologist. 10:231-236
A previous study has provided evidence that a unique glyph at CA-PLA-571 in the Sierra Nevada was probably a trail map. This article suggests two more wavy glyphs on this petroglyph panel as being different trail maps. The evidence that a tracing of

Effect of Pre-Illumination on the Response of Split Pea Stems to Growth Substances
Autor: Martha Kent, Willis A. Gortner
Publikováno v: Botanical Gazette. 112:307-311
1. Light has a marked effect on the response of the seedlings in the pea test for detecting growth-regulating activity of chemicals. Split stems from seedlings grown in complete darkness give little or no response to solutions of growth substances, w

Relation of Chemical Structure to Plant Growth-regulator Activity in the Pineapple Plant: Retarding Senescence of Pineapple Fruit with Applications of 2,4,5-Trichlorophenoxyacetic Acid and 1-Naphthaleneacetic Acid
Autor: Willis A. Gortner
Publikováno v: Journal of Food Science. 34:577-580
SUMMARY: The effectiveness of 1-naphthaleneacetic acid (SNA) and 2,4,5-trichlorophenoxyacetic acid (2,4,5-T) in markedly retarding further ripening of pineapple fruit and thus extending its marketable life as a fresh fruit has been demonstrated. The

Fruit Development, Maturation, Ripening, and Senescence: A Biochemical Basis for Horticultural Terminology1
Autor: Willis A. Gortner, Gerald G. Dull, Beatrice H. Krauss
Publikováno v: HortScience. 2:141-144
The terminology used to describe developmental stages of fruits is often confusing or even misleading. “Mature” and “ripe” are often used synonymously. We find reference to “green” fruit, based on skin or peel color, used interchangeably

Chemical and Physical Development of the Pineapple Fruit III. Nitrogenous and Enzyme Constituents
Autor: Willis A. Gortner, Vernon L. Singleton
Publikováno v: Journal of Food Science. 30:24-29
SUMMARY Nitrogenous constituents of developing pineapple fruit were determined at weekly intervals on two lots of fruit in 1958 and four lots in 1963. Some analyses on shell tissue were included. The fraction of nitrogen in the flesh of the fruit not
