(196) Inducing Lettuce Tipburn with Relative Humidity Modification

Effect of Relative Humidity

HIMMELFARB, PHILIP (University of Massachusetts, Amherst), HAMED M. EL-BISI, R. B. READ, JR., AND WARREN LITSKY. Effect of relative humidity on the bactericidal activity of propylene oxide vapor. Appl. Microbiol. 10:431-435. 1962.-Because of the low toxicity of its breakdown product, propylene oxide (PO) vapor will play an increasingly important role in the preservation of foods. It is therefor...

Relative humidity in incubators.

In a previous paper Hey and Maurice (1968) have reported the effect of changes of relative humidity on the heat production and heat loss in normal naked babies in a specially constructed metabolic chamber under controlled environmental conditions. In order to evaluate the clinical relevance of these observations we have studied the control of relative humidity that could be achieved in three co...

Relative humidity profiling with Megha-tropiques

Exploring the limits of crop productivity: beyond the limits of tipburn in lettuce.

The productivity of lettuce in a combination of high light, high temperature, and elevated CO2 has not been commonly studied because rapid growth usually causes a calcium deficiency in meristems called tipburn, which greatly reduces quality and marketability. We eliminated tipburn by blowing air directly onto the meristem, which allowed us to increase the photosynthetic photon flux (PPF) to 100...
