...plant life involved in the formation of anthracite coal and petrified woods. Never before have botanists been able to secure satisfactory microscopic specimens from these hard rocks. Mr. Darrah has succeeded in making fossil peals of both coal and petrified woods, among them specimens containing the remains of pollen grains more than 200,000,000 years old from a coal deposit in Illinois...
...examined and it was discovered that these super-double flowers were entirely female sterile. They kept on blooming and never went to seed." Because they are "female sterile," the flowers cannot be mated with one another. But not being "male sterile," their strain can be continued by using their pollen to fertilize the double hybrids. The 60-petaled super-double hybrids were shown in Manhattan last week at a special preview for horticulturists, to whom Mr. Burpee recounted the story of his find. The flower has been patented under the name Trapaeolum majus Burpeeii, Mr. Burpee being granted Plant Patent...
Ordinary regal lilies are dehiscent: the pollen-bearing anthers swell, burst open, shower sticky golden dust on the blossoms, marring their virginal immaculacy. GE's lily, which owes its existence to Engineer Chester Newell Moore, is non-dehiscent. Mr. Moore was experimenting with the effects of x-rays on genes and chromosomes (heredity carriers in the germ-plasm). He irradiated 75 bulbs of regal lilies. Nothing noteworthy happened to the first generation, but among the second-generation freaks were two flowers whose anthers shriveled without releasing their pollen. From these two Engineer Moore obtained a true-breeding strain...
Ragweed began to ripen and send its pollen (ten billion grains to the plant) into the air last week. In consequence, some two million peculiarly sensitive residents of the U. S. began to snuffle & weep with their annual attacks of hayfever. New York City, Chicago and smaller communities hired men to pull up every stalk of ragweed within city limits. For one day's pulling Chicago paid 25? and a ticket good for a week's room & board in a charity shelter. Sales of home air filterers perked up. If his sleeping quarters are free from dust...
...several theories of allergy stand out as useful - he protein theory and the reagin theory. Two points are certain about hayfever and the other allergies: 1) certain substances are mildly poisonous to certain people; 2) people react to their personal poisons in specific ways. The irritants may be plant pollens (ragweed, timothy, oak), foods (wheat, milk, eggs, fish), ani maldanders, feathers, dusts. The victim may show his symptoms in his nose and eyes (this is hayfever per se), his skin (hives), brain (migraine), intestines (colitis). Two theories concerning the physiology of allergy have many followers among the specialists. One theory...
