A CONCENTRATION GRADIENT IN CORN STALKS

A Concentration Gradient in Corn Stalks

In a recent paper, Evelyn I. Fernald 1 has shown that the osmotic concentration of the sap of different portions of stems is correlated with the tendency of buds to develop on those portions. She has found by freezing point measurements on the expressed sap that in actively growing stems of privet, chestnut, Pkiladelphus, and Bryophyllum there is a concentration gradient, the highest concentrat...

Microbial conversion of corn stalks to riches.

If all of the corn stover (mature cured stalks with the ears removed) in the United States could be converted annually to an utilizable form of energy such as ethanol, the United States would not have to import as much foreign oil (2; David Johnston, personal communication). This would have a profound effect on energy supply and utilization, on cleaner air and environment, and on worldwide econ...

Energy Requirement for Cutting Corn Stalks (Single Cross 704 Var.)

Corn is cultivated in most countries because of high consumption, quality, and food value. This study evaluated needed energy for cutting corn stems in different levels of cutting height and moisture content. For this reason, test device was fabricated and then calibrated. The device works on the principle of conservation of energy. The results were analyzed using split plot design and SAS soft...

Corn Stalk Nitrate Concentration Profile

knowledge of crop N need may be used by producers to guide future fertilizer-N management thereby improving The end-of-season stalk nitrate test provides a method of assessing profitability and reducing environmental degradation. the N available to the corn (Zea mays L.) crop during the latter part of the season. This study was conducted to determine how stalk nitrate To be a useful crop manage...
