Seasonal variations of leaf water potential and growth in fertigated carob-trees (Ceratonia siliqua L.)

Response to seasonal drought in three cultivars of Ceratonia siliqua L.: leaf growth and water relations

Leaf nutrient variation in mature carob (Ceratonia siliqua) trees in response to irrigation and fertilization.

Seasonal variations in leaf nitrogen, phosphorus and potassium concentrations were studied in a mature carob (Ceratonia siliqua L. cv "Mulata") orchard subjected to a 4-year irrigation and fertilization experiment. Three irrigation regimes (0, 50 and 100%), based on the evaporation values obtained from a class A pan, were tested in combination with two nitrogen (N) supply regimes in which 21 kg...

Clonal Propagation of Carob (ceratonia Siliqua L., Fabaceae)

Mature seeds of carob tree (Ceratonia siliqua L.) were germinated on hormone free MS medium. Efforts were made to develop multiple shoots by using axillary buds of in vitro grown seedlings on MS medium fortified with different concentrations of BA singly and BA in combination with IAA or GA3. Axillary buds produced single shoot with a moderate amount of callus at the base of the explant after c...

Response to seasonal drought in three cultivars of Ceratonia siliqua: leaf growth and water relations.

Responses of leaf growth and leaf water relations to seasonal drought were monitored during two successive years in three cultivars (Galhosa, Espargal and Mulata) of Ceratonia siliqua L. growing in the field in southern Portugal. Leaf water relations of fully expanded leaves were characterized by pressureâ volume analysis, and morphometric measurements of petiolar xylem were made. The three cu...

Effects of Various Treatments on Seed Germination and Growth of Carob (ceratonia Siliqua L.)

In this study, Ceratonia siliqua L. carob seeds harvested from both wild and cultivated genotypes in Turkey were subjected to mechanical scarification, soaking in hot water and dipping in sulfuric acid. All treatments hastened seed germination and seedling growth of carob compared to control. The germination percentage of control seeds were similar for both wild and cultivated genotypes (13%) a...
