Abnormal Cones in Cupressus Sempervirens
Abnormal' cones found irt Cupressus sempervirens include bisexual cones and double female and male cones. They are very infrequent, but there are individual trees ~th a tendency· to produce· ~\Jch cones. We, suggest that these cones reflect changes in normal hohnonal balance. keY, words: Cupressus sempervirens, bisexilal con~s, cones.
متن کاملTerpene arms race in the Seiridium cardinale – Cupressus sempervirens pathosystem
The canker-causing fungus Seiridium cardinale is the major threat to Cupressus sempervirens worldwide. We investigated the production of terpenes by canker-resistant and susceptible cypresses inoculated with S. cardinale, the effect of these terpenes on fungal growth, and the defensive biotransformation of the terpenes conducted by the fungus. All infected trees produced de novo terpenes and st...
متن کاملImpact of insects damaging seed cones of cypress , Cupressus sempervirens , in natural stands and plantations of southeastern Europe
A total of 18 stands of Cupressus sempervireus L. (Cupressaceae) were surveyed in the natural Greek range (plus one stand in Turkey) during 1994-1996 in order to identify the pests of seed cones and assess their impact on seed survival. Naturalised stands of mainland Greece, Albania and Malta were sampled for comparison. The cone entomofauna (seven insect and one mite species) did not differ be...
متن کاملPrevalence and real clinical impact of Cupressus sempervirens and Juniperus communis sensitisations in Tuscan "Maremma", Italy.
OBJECTIVE The aim was to evaluate the impact of Cupressus sempervirens (Cs) and Juniperus communis (Jc) sensitisations in "Maremma" in southern Tuscany. METHODS 811 consecutive outpatients (357 F - 57.86%; age: 36.9 ± 16.6) with suspected allergic respiratory symptoms underwent skin prick tests (SPT) for common allergens and for Cs and Jc. RESULTS SPT resulted negative in 295 (36.37%) subje...
متن کاملEffectiveness of Cupressus sempervirens cones as biosorbent for the removal of basic dyes from aqueous solutions in batch and dynamic modes.
The feasibility of using cypress cone chips from Cupressus sempervirens as a low-cost biosorbent for the removal of two representative basic dyes, methylene blue (MB) and rhodamine B (RhB), from aqueous solutions was investigated in batch and continuous modes. Dyes biosorption was strongly dependent on the solution's pH. Sorption kinetics was determined and properly described by the pseudo-seco...
