Availability of iron in hydroponic nutrient solutions for rose crops
Lykas, C.; Giaglaras, P.; Kittas, C. (2001)This study investigated the effect of light and agitation on the availability of iron in hydroponic nutrient solutions. In recycled hydroponic nutrient solutions used for the cultivation of roses, iron is added usually in ... -
Effects of paclobutrazol and chlormequat on growth and flowering of lavender
Papageorgiou, I.; Giaglaras, P.; Maloupa, E. (2002)Growth retardants allowed production of more uniform, compact, flowering plants for commercial use of lavender (Lavandula stoechas). Paclobutrazol at 200, 400 and 600 mg.L-1 (ppm) was sprayed in a single or double application. ... -
Electrical conductivity and pH prediction in a recirculated nutrient solution of a greenhouse soilless rose crop
Lykas, C.; Katsoulas, N.; Giaglaras, P.; Kittas, C. (2006)The influence of nutrient solution (1) mixing rate, and (2) time of use on pH and electrical conductivity (EC) of a recirculated nutrient solution used for the irrigation of a greenhouse soilless rose crop was studied. ... -
Influence of covering material and shading on the spectral distribution of light in greenhouses
Kittas, C.; Baille, A.; Giaglaras, P. (1999)The solar photon flux distribution was measured in the range from 400 to 1100 nm under a twin-span glasshouse and under the same glasshouse with blanked roof, external shading net and internal aluminized shade-screen. ... -
Noxious gases in greenhouses
Likas, C.; Exarchou, V.; Gourgoulianis, K.; Giaglaras, P.; Gemptos, T.; Kittas, K.; Molyvdas, P. A. (2001)The concentration of NO2 and SO2 was measured in a commercial greenhouse from 23/9/1999-25/01/2000. The measurements showed that the level of the two gases is very high in the greenhouse atmosphere. Lung function tests in ... -
Nutrient solution management recirculating soilless culture of rose in mild winter climates
Lykas, Ch; Giaglaras, P.; Kittas, C. (2001)In a closed hydroponic system with a rose crop, the composition of the nutrient solution in the tank was measured every two days in order to establish the dynamics of the nutrient elements in short-term periods. It was ...
