Abstract:
... 1. Serum chlorate apparently penetrates readily all of the external surfaces of the plant with the exception of unusually heavy cuticle or corky layers and may be expected to gain entrance to the plant whether applied to the leaves, to herbaceous stems, to rhizomes, or to roots. 2. The data presented indicate that the movement of sodium chlorate within the plant is principally in the xylem and is ...

Abstract:
... Comparative cost and effectiveness of tillage and chlorates are reported for morning glory, Canada thistle, and perennial sow thistle.

Costs were based on each plowing at $3 an acre, each cultivation at 50 cents an acre, and chlorates at 10 cents a pound, including cost of application. A ...

Tests of their ability to endure low temperatures showed that they became more hardy as cold weather came on. Canada thistle was found to be relatively susceptible to injury by freezing. If photosynthesis w ...

Abstract:
... Volatility of atrazine (2-chloro-4-(ethylamino)-6-isopropylamino-s-triazine) from glass, plant, and soil surfaces was determined by passing air above the experimental material through Florisil³ columns. Atrazine volatility was determined by counting the ¹⁴C-atrazine present in the column eluate and that remaining on the treated surfaces. Volatility from 125-ml glass erlenmeyer flasks was influence ...

Abstract:
... Many hypotheses have been developed to explain the adaptive nature of insect galls. One of these, the nutrition hypothesis, states that gall formers have advantages over other insects because gall tissue provides a better (higher quality) food source than unmodified tissue. However, this has rarely been experimentally tested. In a test of this hypothesis, we grew plants of Cirsium arvense (L.) Sco ...

To identify which compounds in a floral scent are more attractive and, thus, of biological importance to foraging butterflies, we applied electrophysiological methods. Antennal responses of male and female adults of the tropical butterfly Heliconius melpomene L. (Lepidopt ...
