... Five years after planting, measurements of soil moisture and temperature, leaf nutrient concentrations and growth, were compared for plots of northern red oak, white oak, and shortleaf pine for treatment combinations that included two levels each of harvesting intensity (organic matter removal), site disturbance (soil compaction), and weed control (control of the understory). There were significan ...

Abstract:
... Mosaic is the most widespread viral disease of fig, affecting the crop wherever it is grown. The causal agent of the disease was poorly characterized and until recently it was considered a virus-like agent with double membrane bound semispherical bodies transmitted by eriophyid mites. During the molecular characterization of the Fig mosaic virus we discovered two new closteroviruses and a new badn ...

Abstract:
... In timothy breeding, which is a comparatively new phase of experimental agronomy, standard methods have yet to be worked out and adopted. Several methods which have recently been developed for making comparative quantitative studies of different selections or varieties of timothy are described in this paper.Through the use of certain definitions which describe timothy plants in different stages of ...

Subject:
alfalfa; methodology; transpiration; alfalfa hay; leaves
Abstract:
... Windrowing and cocking relatively green hay materially extended the curing period as compared with swath curing. Prolonged swath curing resulted in undue loss of leaves and bleaching. Judicious, partial swath curing to hasten the rate of drying, followed by windrowing and by prompt storage when cured would seem to be the best farm practice for this region. The normal transpiratory function of the ...

Abstract:
... In a study of inheritance in G. hirsutum, no sterility, abnormal characters, or non-Mendelian segregations were observed in the F1 and F2 generations of crosses between standard and unimproved varieties. This is in contrast to the findings of several workers who made studies of the inheritance in crosses between G. hirsutum and G. barbadense. The characters naked seed and fuzzy-tip seed proved to ...

Abstract:
... When only nitrogen, phosphorus, and potassium are supplied in the fertilizer on some soils the growth of the tobacco plant exhibits definite pathological symptoms and growth is decidedly reduced. The addition of magnesium results in some increase in growth, but the growth still may be abnormal. This abnormality consists of development of upper leaves of the plant in which the tips and margins are ...

Abstract:
... A peat soil that was unproductive for lettuce was made more productive for the growth of the plant by treating the soil with lime and the seed with CuO. The action of the lime was to correct a soil condition that caused the plants to become chlorotic, the leaves to curl, the appearance of necrotic spots at the tips and on the margins of the leaves, and the death of the plants in the early stages o ...

Abstract:
... 1. A list of genes and a chromosome map are given to show the progress made to date in a genetic analysis of the soybean. 2. The mode of inheritance of three characters is described. Bloom on the seed coat is considered to be due to three complementary genes B1, B2, and B3, all three of which must be present to produce the character. Variegated leaf (v1) is a simple recessive to normal (V1), and d ...

Abstract:
... In 1925, 300 well-shaped sugar beets were selected from a commercial field of the Janascz variety. Sugar tests, later examination of root shape, and a few storage losses reduced this number to 120, of which 100 grew. A few branches of 75 of these mother beets were covered just before the flowers opened with 2-pound grocery bags and seeds were obtained under bags from 59 of the plants. Seeds from t ...

Abstract:
... This short sketch on the variability and diversities of maize phenotypes leads us to the conclusion that genetic investigations have not yet exhausted the phenotypical richness in the maize plant. The group of extra-late corn varieties (having over 30 leaves) has been left completely out of the genetic investigation. This group is very interesting, because by its distribution it is connected with ...
