Book Description
Excerpt from The Effects of Cross and Self Fertilisation: In the Vegetable Kingdom There is weighty and abundant evidence that the flowers of most kinds of plants are constructed so as to be occasionally or habitually cross-fertilised by pollen from another flower, produced either by the same plant, or generally, as we Shall hereafter see reason to believe, by a distinct plant. Cross-fertilisa tion is sometimes ensured by the sexes being separated, and in a large number of cases by the pollen and stigma of the same flower being matured at different times. Such plants are called dichogamous, and have. Been divided into two sub-classes: proterandrous species. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
Excerpt from The Improvement of Naturally Cross-Pollinated Plants by Selection in Self-Fertilized Lines, Vol. 2: The Testing and Utilization of Inbred Strains of Corn The application of inbreeding to the improvement of corn has received an increasing amount of attention since its inception a quarter-oi a century ago. In 1932 more than acres of corn were planted in this country with seed that had resulted, in one way or another, from the crossing of inbred plants. Although the production of hybrid corn seed seems to be well started in commercial practice, the development, testing and most advantageous use of inbred strains still present many problems. The first attempt to account for the increased growth immediately resulting from cross-fertilization may be called the physiological hypothesis of hybrid stimulation. In this it was thought that the bringing together of germinally diverse elements by crossing different lines, generated the growth activity commonly referred to as hybrid vigor. Conversely, the reduced size and slower growth rate of inbred lines was considered the natural result as the germinal constitution is simplified.
