Researches regarding some features of apple pollen tubes
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iași, 2015) Iordache, Maria; Oltenacu, V.; Ilie, A.
The pollen tubes are not always appropriate in pistil penetrating. The object of this work is to present two types of “features” that occur during the pollen germination process in vitro at some apple varieties like Pionier and Generos regarding the development and the pollen tube aspect in experimental conditions on different culture media. The manifestation of these “features” was observed on other additional experiments of apple varieties which suggests that it is an “anomaly germination”, especially dependent on the species and it is not just a characteristic of the variety own. The microscopic examination of pollen germination analysis was performed by transmitted light and in phase contrast for highlighting of the pollen tubes and pollen nucleus. This kind of germination was observed in three replicates at the rate of 1 to 5%.

Involvement of water in coordination and integration of plants ́ functions in drought conditions
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iași, 2015) Ștefîrță, Anastasia
It was established that water in unfavorable conditions is one of the main factors of integration and coordination of physiological processes at the cellular, organ and organism level. The water stress caused disturbances in the functional interrelationships between organs as a result of differences in the degree of dehydration, the occurrence of reactive oxygen species and the antioxidant enzyme activities, especially in roots and inflorescences. The reason of the functional imbalance in drought conditions was the reduction of water and phytohormones transport, disturbed water homeostasis, and decreased enzymatic antioxidant protection. It was confirmed the hypothesis that water is the factor involved in regulating the functional activity of the plant, helps maintain coordinated relations between organs and performs, along with other factors, function integration at the organism level.

Physiological processes associated with the resistance of Glycine max (Merr., L.) plants to repeated water stress
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iași, 2015) Leahu, Igor; Ștefîrță, Anastasia; Toma, S.
The experimental data were obtained on the reasoning behind the meaning of water homeostasis significance and antioxidant protection in the event of potential resistance of Glycine max L.(Merr) plants to the hydric and oxidative stresses, conditioned by in time repeated drought. It was established that the primary reaction of soybean plants to drought action is changing the parameters of the water status and tissue dehydration, coupled with the formation of reactive oxygen species (ROS), an increase of malonic dialdehid (DAM) and peroxide oxidation of lipids. Dehydration and ROS formation causes destruction of chloroplasts and diminish fund assimilating pigments in the leaves of both cultivars, especially in sensitive plants.Water stress caused closure of the stomata, the inhibition of carbon dioxide assimilation, with the negative consequences on the of water use efficiency in the production process. The plants, which have suffered a moderate drought at the initial stages of ontogenesis, exhibit a greater tolerance to repeated drought during critical period.

Feautures of water status and antioxidant protection of plants with different adaptation strategies to drought
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iași, 2015) Brînză, Lilia
There have been registered differences caused by drought in competitive relationships between plant organs of Phaseolus vulgaris L., Phaseolus acutifolius Gray, and Phaseolus lunatus L. The inflorescences and pods of resistant plants possessed a better water homeostasis by account of water reserve from the stems, of root system activity and reactivity of stomata. Reactivity of stomata, hydraulic conductivity adjustment, high ability to restore the water status of the tepari and Lima beans reflected the conservative strategy of tolerant plants. Low tolerance of Phaseolus vulgaris L. plants to drought could be explained as the result of lower stomatal conductance, the occurrence of reactive oxygen species, acceleration of lipid peroxidation, accelerating oxidative destructions

(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iași, 2015) Trincă, Lucia-Carmen; Mareci, Daniel; Ariton, Adina-Mirela; Tucaliuc, Roxana-Angela; Călin, Marius; Chiruță, Ciprian
Phenolic compounds from various food matrices can be investigated with different analytical techniques such as spectrophotometric, cromatographic or electrochemic methods. Cupric Reducing Antioxidant Capacity method (CUPRAC) is a convenient assay for determining total antioxidant capacity in food substrates. In this work, electrochemical and spectrophotometrical approaches were used to estimate the total antioxidant capacity by means of an alternative of the CUPRAC assay, as the concentrations of the participating species ([Cu(Nc)2]2+ and [Cu(Nc)2]1+) can be evaluated by electrochemical and spectrophotometrical methods. The electrometric–CUPRAC methods have been applied to measure total antioxidant capacity of different local wines and validated against the spectrophotometric CUPRAC assay. The electrochemical methods proved to be easy, fast and with low detection limits. A good correlation for the total antioxidant capacity determined by CUPRAC spectrofotometric and electrometric method versus total phenol content (determined by Folin-Ciocalteu Method) was recorded, wich highlights that wines antioxidant activity results mainly from their phenolics content.
