Abstract

  To study the germination traits, determine the bed culture and some of the agronomical traits of the medicinal plant (Scrophularia striata), a series of experiments accomplished in the Agricultural and Natural Resources Department of University of Tehran in 2016. Investigation of seed dormancy and germination was done in factorial design in three replications with three factors including gibberellic acid (at 0, 100 and 400 ppm conc.), chilling duration of 0, 1, 3, 5 and 7 days, and temperatures of 5, 10, 15, 20, 25, 30 35oC. The highest germination percentage (58.7%) occurred at 15°C and in zero and 400-ppm conc. of gibberellic acid and 7 days chilling. In the greenhouse, seven different bedding types used in a randomized complete block design with four replications to determine the establishment and emergence of seedlings. The highest percentage of seedling emergence (56.6%) found in peat moss and peat moss + perlite (1 : 1) with was no significant difference between the two treatments. In the field experiment, the effect of different dates and bedding types on phonological and agronomic traits of Scrophularia plant sp. performed in a split plot design with randomized complete block design at three replications. Five planting dates (June, September, October, November, and March) and three planting bed (peat moss, perlite + peat moss and coco peat + perlite + peat moss) treatments examined. The time of different phenological stages in terms of growth degree-day (GDD) estimation, showed that the June planting date (in peat moss bed) required the lowest GDD as compared to other treatments. In relation to agronomic traits of Scrophularia plant sp., number of main branches, dry weight of shoot, capsule weight per plant, etc. recorded the highest values of traits in the latter treatment.
