Title

PLASTICITY OF LEAF ANATOMY, CHEMISTRY AND WATER ECONOMY OF IRRIGATED SUGAR BEETS GROWN UNDER MEDITERRANEAN CONDITIONS

Pages

  99-114

Abstract

 In a three-year (2004-2006), field experiment, we aimed to study changes in leaf physiological traits (leaf water potential-Yleaf, leaf water content-LWC, CARBON ISOTOPE DISCRIMINATION-D, SPECIFIC LEAF AREA-SLA, chlorophyll content as assessed by SPAD and modified SPAD-MSPAD) and elemental composition (K, Na, Ca, Mg, K/Na, Ca/Mg, total leaf salinity-TLS) of sugar beets (cv. Rizor) grown under Mediterranean, irrigated conditions. Each year, soil moisture content (SMC) and leaf parameters were determined 11 times from early June to the end of October. Growing seasons differed as regards water inputs with 2004 being the driest and 2006 being the wettest. Leaf physiology and chemistry showed plasticity to water availability and significant differences were found between years (except for Ca), sampling time and their interaction. Yleaf, LWC, D, SLA, K/Na and Ca/Mg were positively affected by SMC while the adverse was evident for chlorophyll content (SPAD and MSPAD), Na, Ca, Mg and TLS. As a Chenopodiaceae, sugar beet used leaf succulence, lowering SLA, to cope with water shortage and maintain LWC ca 90%. Low SLA was related with low Yleaf and D values. Succulent leaves were characterized by increased leaf salinity and chlorophyll accumulation, which was ascribed to increased Mg concentrations. Leaf salinity and mainly Na had a negative impact on D. Antagonistic effects of K on Na or Mg and synergistic effects of Na on Ca and Mg were recorded.
