Stimulation of bluegrass seed germination by soaking and drying treatments

Creator:

Onul, Taylan

Abstract:

The objective of this study was to develop a soaking and drying procedure to stimulate faster germination of Kentucky bluegrass (Poa pratensis L.) seed. The seeds were soaked in cheesecloth bags in nine chemical solutions. The effects of temperature and time of soaking and of aeration of the solution were...

Masters Thesis
Temperature preconditioning of ryegrass (Lolium sp.) seed dormancy

Creator:

Wiesner, Loren E.

Abstract:

The purposes of this study were to determine the effects of temperature, nutrients, growth regulators, and culm detachment during seed development on ryegrass seed dormancy and weight. The effects of storage temperature on seed dormancy were also studied. Seed dormancy of annual (Lolium multiflorum Lam.) and perennial (Lolium perenne L.)...

Dissertation
Utilization of the night-interruption phenomenon to hasten the seed increase of long-day cereals during short-day regimes in California and Arizona

Creator:

Ebeltoft, David C.

Abstract:

Tests were carried on in growth chambers and in the field to determine if the harvest of daylength-sensitive long-day cereals grown during the winter in Arizona could be hastened 30 days by the use of night interruption. Two durum lines which were near-isogenic for sensitivity to daylength were used throughout...

Dissertation
Effect of seed protein content on plant growth of barley and wheat

Creator:

Lopez, Arturo

Abstract:

The purpose of this study was to evaluate the effect of seed protein content on plant growth of barley (Hordeum vulgare L. ) and wheat (Triticum aestivum L. ). The effects of nitrogen application on chemical and morphological characteristics of the seed were also studied. Seeds of 'Casbon' winter barley...

Presoaking and drying treatments to improve the performance of orchardgrass and bluegrass seed

Creator:

Haight, John Colson

Abstract:

The objective of this study was to develop a soaking and drying procedure to stimulate the germination and seedling emergence of orchardgrass (Dactylis glomerata L.) and Kentucky bluegrass (Poa pratensis L.) seed. Some of the physiological changes associated with the soaking and drying treatments were also studied. The seed was...

Masters Thesis
Effect of nitrogen fertilization of wheat (Triticum spp.) on chemical and biochemical composition and performance of seeds

Creator:

Garay, Adriel Edgardo, 1945-

Abstract:

High protein wheat seeds frequently perform better than low protein seeds of the same variety. Protein content of seeds can be increased by management practices, the most important of which is rate and timing of N applications. The purpose of this study was to determine the chemical, biochemical and physiological...

Masters Thesis
Identification of species and varieties of ryegrass (Lolium spp.)

Creator:

De Barros, Manoel Bernardo

Abstract:

The objective of this study was to investigate ryegrass seedling characteristics that, by themselves, or combined with presently known characters, could improve varietal identification tests. Thirteen characters were studied on 30 varieties of Lolium multiflorum Lam., L. perenne L., L. rigidum Gaud, and L. hybridum Hausskn., including leaf size and...
