The aim of this study was to evaluate the sugarcane responses to varying ammonium:nitrate (NH4+:NO3−) ratio and to reveal how much NH4+ plants can tolerate before showing impairment of photosynthesis and growth. Sugarcane plants were grown in nutrient solution with the following NH4+:NO3− ratios (%): 20:80; 30:70; 40:60; 60:40; 70:30; and 80:20. The lowest photosynthetic rates, stomatal conductance, instantaneous carboxylation efficiency and leaf chlorophyll a content were found in plants suppli...
Photosynthesis is the most important source of dry matter production directly influencing grain filling in wheat. Croatian winter wheat varieties, ‘Vulkan’ and ‘Golubica’ have similar genetic yield potential but in previous years ‘Golubica’ failed to achieve it. In order to find reasons of that, we evaluated photosynthetic (JIP test) and oxidative pathways (antioxidative enzymes and non-enzymatic components) in flag leaves of both wheat varieties from flowering till late milk development stage. ...

Electrical impedance spectroscopy (EIS) is a useful tool for the investigation of the structural characteristics of solid materials and also biological tissues. The structural changes in plant or animal tissues reflect the physiological state of the organism. Electrical impedance measurement seems to be applicable both for analytical and research laboratories, since once a stress or a quality trait is correlated with an impedance parameter the method is quick and safe for further analysis of gre...

Sodium benzoate (NaB) is widely used as food and drink preservative. However, little is known about the phytotoxic effects of NaB on plants. The aim of this study was to evaluate the phytotoxicity effects of exogenous sodium benzoate on seed germination and seedling establishment of rice plants. Seeds were treated with 0, 5 and 10 mM of NaB in a growth chamber with controlled conditions. NaB decreased the germination rate, plant growth and biomass accumulation. Increasing NaB concentration resul...

In seasonal systems, species have specific traits to deal with water shortage. This is the case for plants in Neotropical savannas, where the dry season can endure 3 to 5 months without rain. Ecophysiological strategies to deal with the dry period are well known for savanna trees, however little is known for non-arboreal species such herbs and subshrubs concerning their water use strategies. In this study we analyzed traits related to water and nutrient storage in underground organs and leaves o...

In the current context of climate change, evaluation of intraspecific genetic and phenotypic variability of lentil (Lens culinaris Medik) in response to early droughts is fundamental to gain novel insight on the adaptive potential of lentil to water deficit. Here we studied in the field the variability of functional traits, leaf biochemical composition and yield components of three Spanish lentil cultivars submitted to an atypically dry spring. The genetic variability was also studied using ampl...
The success of the ecological restoration depends on the appropriate determination of species for implantation in restoration areas. The use of physiological performance as a criterion may help in the selection of species that are less susceptible to abiotic stress, and consequently experience a lower mortality rate. Species of the same genus can even exhibit differences in physiological responses to water deficiency. Thus, we hypothesize that congeneric species have different physiological resp...
Source–sink balance is a major determinant of carbon partitioning within plants. Thinning is an agronomic practice that consists of changing the ratio between leaves and fruits, the source and sink plant organs, respectively. Decreasing the fruit load on a peach tree is supposed to lead to an increase in fruit size and sometimes in soluble solid content in the remaining fruit. However, this response would change in early and late harvest peach varieties when considering the reduction in sink org...

Temperature of sporophylls from excised male cones of three species from the Zamiaceae family (Ceratozamia miqueliana, Zamia fairchildiana, and Zamia pumila) and from one species from the Cycadaceae family (Cycas siamensis) was recorded over several days in an environmental chamber. Each species exhibited a different temperature profile. C. miqueliana and Z. fairchildiana were highly thermogenic, whereas C. siamensis and Z. pumila were weakly thermogenic. In C. miqueliana, the temperature of one...

The Arabidopsis thaliana genome contains many genes that encode proteins with a domain of unknown function (DUF). To improve our understanding of the functions of these DUF family members, a DUF761-containing gene at the At4g16790 locus was isolated and designated DUF761-1. Duf761-1 loss-of-function mutant did not significantly affect plant growth and development, whereas transgenic plants overexpressing DUF761-1 exhibited several unique phenotypes during vegetative and reproductive growth. DUF7...
