The response of the heated glasshouse lettuce crop to in situ supplements of low illuminance fluorescent light


, : The response of the heated glasshouse lettuce crop to in situ supplements of low illuminance fluorescent light. Acta Horticulturae (51): 185-200

Comparisons were made between light applications begun at different times of the day and night but given for the same period of time. The supplements were provided for the greater part of the growth period of the crop. The response was measured in terms of changes in dry matter, leaf area, stem length and time to head formation.

B., 2003: Identification and characterization of auto-anti-idiotypic antibodies specific for antibodies against porcine reproductive and respiratory syndrome virus envelope glycoprotein (GP5). Auto-anti-idiotypic antibodies (Aab-2s) were detected from pigs experimentally infected with porcine reproductive and respiratory syndrome virus (PRRSV). The Aab-2s were specific against the idiotypic antibodies (Ab-1s) to the envelope glycoprotei...
