Cutting-time effect during harvest cycle on postharvest behavior of three Gypsophila paniculata cv. Perfecta clones.

 

Cuttings from clones Balborts, Raham Meristem and Cor van Duyn were planted and monitored under identical commercial greenhouse conditions at 2600 m a.s.l. The optimum harvest time was based on the presence of 50% open corollas in every shoot. Vase life was recorded at 5, 15, 30, 45 and 55 days after the first harvest. The shoots were submerged in a STS-sugar-bactericide mixture for 2 h, then 3 flowering shoots were placed in every vase, and maintained in the laboratory under constant light, temperature and relative humidity. Tap water was used and replaced every 3 days. One branch of the shoot was marked in order to determine the opened and necrotic flowers. Harvest period lasted 82 days, Balborts being the earliest clone. There was considerable variation in the number of bunches produced by each clone. The most productive clone was Balborts and the least productive was Cor van Duyn. Vase life and quality were greatest for the first harvest of Raham Meristem and Cor van Duyn clones and for the

second harvest in Balborts. Quality and vase life were similar in all clones when the flowers were cut on day 30, 45 or 55. Senescence began slowly 7 days after placing the flowers in vases in all clones. Fading increased with time.
