Pollen Fertility and the Vegetative Growth of Various Eggplant Genotypes Under Low Temperature Greenhouse Conditions

Phenological Development and Production Potentials of Tomato under Polyhouse Climate

“…Baytorum et al, (1999) mentioned that tomato yield was higher in heated greenhouse than in unheated greenhouse up to the end of March. The lower minimum temperature levels reduced or delayed the fruiting process of tomato (Romano and Leonard, 1994) and it might create problems for the vegetative and generative growth (Abak and Guler, 1994). The leaf temperature of 13ºC may cause the reduction in physiological activity of cucumber plants due to low temperature stress (Roh et al, 2007) and it prevent fertilization in tomato by reducing pollen count and viability (Ercan and Vural, 1994) and therefore, decreases fruit set and the yield (Rylski et al, 1994).…”

Performance of the predator Amblyseius swirskii (Acari: Phytoseiidae) on greenhouse eggplants in the absence and presence of pine Pinus brutia (Pinales:Pinaceae) pollen

“…This predator is a well‐known pollenophagous species, and its failure to control F. occidentalis could be in part attributed to the lack of alternative food sources, such as pollen, on these plants. Eggplants not only produce little pollen in winter but also the pollen produced by these plants is generally of very low quality (Abak & Güler ). The availability of pollen as alternative food, the presence of oviposition sites and shelter are factors that play an important role in the establishment and efficiency of biological control agents (Kreiter et al ; Nomikou et al ; Romero & Benson ; Walter 1996; Wackers ).…”

Assessment Results and Reflections of Some Eggplant Breeding Projects Performed in Turkey

“…The plants are exposed to low temperatures during its growth and development stage throughout the winter season. The growers usually do not use heating systems to provide optimum conditions for growing due to high heat cost, while take simple preventions to chilling (Abak and Guler, 1994). Although eggplants are warm climate crops, optimum conditions could not always be provided due to the reasons mentioned above.…”
