UNIVARIATE AND MULTIVARIATE ANALYSIS OF SOME GARLIC LANDRACES FOR BULBS TRAITS

The objectives of this paper were to evaluate 12 garlic landraces collected fromSouth-Western saline area of Timis County regarding the bulbs traits and interrelationship among them, with a view to exploiting some of these landraces directly in the crop or using these landraces in breeding program. In this region growers use mostly garlic landraces with a high adaptability to specific environmental conditions, like soil salinity.The results prove the existence of a large phenotypic diversity of bulb traits, even between landraces from the same location (Livezile, Sanmartin, Foieni) which suggests that the adaptation to specific environmental conditions have been associated with different morphological features of bulbs. The height followed by the diameter of bulbs has a significant contribution to the achievement of theirweight

ASSESSMENT OF PHENOTYPIC DIVERSITY FOR SOME RED ONION LANDRACES FROM TIMIŞ COUNTY

The study`s aim was to assess the phenotypic diversity of bulb traits (shape index, diameter, height and weight) in 15 red onion landraces grown in saline areas of south western TimişCounty. In this region growers use mostly red onion landraces with a high adaptability to specific environmental conditions determined by the abiotic stress factors, including soil salinity. The obtained results showed that significant differences in bulb traits were present between the landraces. This study found that the diversity of the studied red onion landraces was distributed within, as well as among landarces from the same location. Some of the landraces like Sânmartinu S. 18, Livezile 151, PeciuNou 99 and Uivar 305 with favorable traits could be selected for further research and utilization

SALINITY STRESS INFLUENCE CUPON SOME PHYSIOLOGICAL PROCESSES IN BEAN GENOTYPES

Phaseolus vulgaris has a great variability regarding the tolerance to saline stress, starting with values of 1 - 5 atm NaCl P.O.The seeds from the control variant V0 were moistened with distilled water. Also we studied the proline content in stresed bean variant. The experimental results achieved made evident the existence of some bean genotypes with a good tolerance to salinity regarding germinative response (Tincova), free proline acumulation (Santana) and dry matter content (Tincova). These genotypes have recorded during germination normal intensities of radicle growth and cotyledon development, and they have synthesized important amounts of free proline with osmoprotector role. We also measured the of stressed genotype
