Postharvest Performance Of Cut Marigold, Rose, And Sunflower Stems As Influenced By Homemade And Commercial Floral Preservatives, Iftikhar Ahmad, John Martin Dole
Turkish Journal of Agriculture and Forestry
Effects of homemade or commercial floral preservatives, applied as 48-h grower treatments or continuous retailer/consumer applications, were studied on cut Double Eagle marigold, Red Bentley rose, and Sunbright sunflower. Cut stems of marigold placed in preservative solutions, irrespective of the duration, had a longer vase life than stems in tap water. Continuous use of soda (7 Up) or citric-Kathon and short-term use of citric-Al resulted in the longest extension of vase life. Cut stems of rose had the longest vase life when pulsed with citric-Kathon for 48 h or continuously placed in citric-Al until termination. For sunflower, use of citric-Kathon …

Optimization Of Orius Majusculus Release: Photoperiodic Sensitivity At Different Temperatures And Storage Of Diapausing Adults, Şeri̇fe Ünal Bahşi̇, İrfan Tunç
Turkish Journal of Agriculture and Forestry
The photoperiodic sensitivity and storage of Orius majusculus (Reuter) from Antalya was investigated to obtain data for the optimization of its release. In the current study, it was not possible to induce a high (up to 100%) incidence of diapause unless all the nymphal instars and adults were successively exposed (i.e. full exposure) to a short day length (11.5 h) at constant temperatures of 18 and 26 °C, and fluctuating temperatures of 10/26 °C. Hence an intermittent exposure to long day lengths, even for short periods of time (only during instars IVV or adult stage), would avoid a high incidence …
