The research was performed during October 2007 and February 2008 within the Laboratory of Air Quality from the University of Agricultural Sciences and Veterinary Medicine Cluj – Napoca. The average values recorded in analyzed parameters of the laboratory indoor air gualities were within the admitted values. A positive, relatively strong correlation (r = 0.78487) was recorded between NO and NOx evolution of the laboratory indoor concentrations. The laboratory indoor air conditions being maintained within the same parameters during the entire experimental interval, the big increase of the majority of analyzed indices in the end of 2007 may be explained only due to some alterations of the outdoor air quality. The air monitoring system made up of HORIBA air pollution devices (APMA-370, APNA-370, APOA-370 and APSA-370) is feasible, environmentally friendl...

Mitochondrial DNA was amplified with four pairs of primers (H1,H2,H3 and H4) and after that the products of amplification were digested with Hha I (for H1 products of amplification), Msp I (for H2 products of amplification) and Eco R I (for H3 and H4 products of amplification) restriction enzymes. On this basis we have established that the ten Phytophthora infestans accessions belongs to two haplotypes, one accession belongs to Ia haplotyp and the others belong to IIa haplotype.

Currently, there are used the projections and estimates of future climate change effects on plant diseases. In our study we aimed to identify the climatic factors with main importance in mapping potato disease in climatic conditions of the county of Cluj, using meta-models, represented by factorial analysis. The experiments developed during 2012-2014 in Poieni, county of Cluj, in a potato filed. Data were processed with STATISTICA software v7.0. for windows. In analyzed experimental field located in Poieni Village, county of Cluj, the factorial analysis revealed that only temperature and humidity are responsible for most of the variance.

The experimental results underline the fact that the attack level expressed through intensity and attack degree is different, both with the “out of root” fertilized variants and with the soil fertilization variants. The conclusions which come off the study of the obtained data point out at the fact that the fertilizer application, no matter the method, determines the growth or the regress of the attack degree. They also have an influence upon the Puccinia striformis f.sp. tritici, Blumeria graminis and, Septoria spp. fungus manifestation.

The national legislation which has implicitly become European legislation harmonized with the international one, focuses on the protection of the natural environment and of the one created by man, the protection of life on Earth. Within this large context, the intervention of the law maker in most countries is directed with realism toward the new and ever changing challenges in this domain, thus giving birth to a set of State bodies, as well as non-governmental bodies, which are charged with the protection of plants, of humans and of life against the harmful influences of pollution of any kinds.

Datorită acestui fapt, in studiul de faţă s-a urmărit abordarea ei din prisma interacţiunii mai multor factori (fertilizare - soi - grad de atac) la fructele de prun, prin aplicarea analizei de regresie multiplă. Experimentul s-a realizat pe parcursul a trei ani: 2007, 2008 si 2009, utilizându-se soiurile:, in condiţiile aplicării a trei ingrăsăminte foliare si a tratamentului cu 10 fungicide. S-au obţinut corelaţii multiple foarte puternice (0,999 – 0,893) pozitive, intre soiurile analizate, fertilizare si tratament in toţi anii experimentali. Conform dreptlor de regresie, aplicarea fungicidelor are drept consecinţă, in toate cazurile, reducerea gradului de atac. La toate soiurile studiate s-a obţinut o corelare moderată a acestora in condiţii de fertilizare - tratament cu cele inregistrate in condiţii de fertilizare in lipsa tratamentelor, dar cu grade de dispersie diferite.

Plant irradiation during the germination period, by using environmental low level microwave radiation (known as electrosmog) alters the plant germination and the growing process. In order to analyze if such a subtle effect is generated only by the microwave irradiation, the environmental parameters (light, temperature, and humidity) must be kept identical for the reference and the irradiated lot. This is a difficult task because the humidity and temperature are interrelated. In order to study the plant behavior under microwaves low power irradiation, the paper describes the design, manufacturing and operating process and device performances on plant growth. To this end, a low power microwave field (average microwaves power density of 3.8mW/m2) under controlled environmental parameters is used. The device consists of a reference chamber (R) and a microwave irradiation chamber (I), of 0.5m3 volume each one, equipped with access doors. The irradiation chamber ensures microwave field distribution with programmable power, frequency and bandwidth in the most commonly used standards for network communication such as: Global System for Mobile Communications (GSM900/1800), Code Division Multiple Access (CDMA), the third generation of mobile telecommunications technology (3G) or 2.4/5GHz Wireless Local Area Network (WLAN). Both chambers provide a radiofrequency (RF) shielding (at least -60dB) against and toward outside, so the electrosmog is shielded and does not interfere with the inner environment. Both chambers are equipped with performing temperature/humidity sensors and controlled LED lighting system (maximum 400µmolcm-2s-1) with a uniformity of ?5µmolcm-2s-1 measured at the bottom level of the chamber. An embedded system (microcontroller) measures the temperature and humidity and proceeds continuously to match the humidity into the chambers pair with less than ?1.5% relative humidity (RH) difference, by using a low flux exhaust ventilation process through a simple innovative method. The accuracy of the temperature measurement is better than ?0.2?C. Humidity and temperature data set are logged (with programmable acquisition rate) during the whole experiment and can be read later by a personal computer. To identify the influence of microwave treatment on bean seeds and plants development, three growing experiments were settled, based on 122 bean seeds each. The number of germinated seeds (determined each day during 8days of experiment), the germination energy (GE %) of the seeds, the length of stems (SL) and roots (RL), the germination (G) %, the seedling vigor index (SVI) and dry matter content (DM%) have been measured and computed. The obtained data showed significant increase for all parameters on microwave irradiation condition.
