Abstract
Saltcedar (Tamarix pentandra Pall.) stem cuttings responded vegetatively to various photoperiods of 11-, 14-, 17-, and 8 + 1-hour duration. Total stem length, average stem length, cuticle thickness, and xylem vessel member outside diameter were significantly maximal under a 14-hour photoperiod and less under photoperiods above and below this level. Numbers of stems and roots produced were significantly less in an 11-hour than under a 14-hour photoperiod; but neither was significantly different from responses under 17- and 8 + 1-hour photoperiods. Vegetative photoperiodic responses, except for cuticle thickness, were affected by a photoperiodic after-effect produced by cuttings collected on various dates. Average stem length, total stem length, and number of stems produced were significantly correlated with field photoperiods from November to May.This publication has 0 references indexed in Scilit:
