Narcissus-Bulb Quarantine. Revised Regulations under Notice of Quarantine no. 62

, : Narcissus-Bulb Quarantine. Revised Regulations under Notice of Quarantine no. 62. U.S. Dept. Agric., Fed. Hortic. Bd, Washington, D.C., 6

This revision of the regulations governing the inspection and certification of narcissus for interstate movement includes several minor changes but retains the important features of the regulations already in effect. If bulbs are infested with bulb flies (Merodon equestris, F., and Eumerus spp.) alone, the time of immersion in hot water is one hour, computed from the time the water regains the loss of temperature occasioned when the bulbs are submerged.

A simple and selective assay for monomeric and filamentous actin is presented, based on the inhibition of DNAase I by actin. In mixtures of monomeric and filamentous actin, only the monomeric form is measured as DNAase inhibitor. The total amount...
