| Popis: | Chitosan and seaweed extract are natural stimulants that are used to improve plant growth and flowering. Therefore, two pot experiments on tuberose plants were conducted during the two consecutive seasons of 2017 and 2018 at Horticulture Research Station at Mansoura, Dakahlia Governorate, Egypt. The aim of the study was to evaluate the response of tuberose plant (single flowers known as Balady variety) to different concentrations of chitosan (CHT) and seaweed extract (SWE) rates on growth, flowering, bulb production and some chemical constituents. Tuberose plant was sprayed six times per season with different concentrations and rates of natural stimulants under study i.e. T1 (control), T2 (20 ppm CHT), T3 (40 ppm CHT), T4 (60 ppm CHT), T5 (0.5 cm3/l SWE), T6 (1.0 cm3/l SWE), T7 (1.5 cm3/l SWE), T8 (20 ppm CHT + 0.5 cm3/l SWE), T9 (40 ppm CHT + 1.0 cm3/l SWE) and T10 (60 ppm CHT + 1.5 cm3/l SWE). These ten treatments were laid out in a randomized complete block design (RCBD) with three replicates. Generally, chitosan or/and seaweed extract treated tuberose showed significant increase (p |
