Abstract: 

The research was carried out in Damsarkhu area of Latakia province during 2022 agricultural season, by cultivating sixteen genotypes of the local ordinary lobby, with the aim of studying the genetic variations in the physiological, morphological and productive characteristics of the locally cultivated species vigna.ssp, and identifying genotypes with distinctive characteristics, using  random complete block design  (R.C.B.D) with three replications. The results showed a differences in the values of the studied qualities while as the genotype (G3) was the most distinctive in many morphological qualities such as the length of the century (30.26) cm, and in productivity, the most important of which is the quality of the number of seeds/century compared with other genotypes (18.46) seed and average plant production of green horns in the area unit (3.15kg/m2), in addition to the genotype (G5), which characterized with the number of green horns on the plant and reached (34.53) horns, and the genotype (G10), which exceeded the size of the leaf (70.91) cm2. Thus, aggregate selection for distinctive strains or varieties can be applied in their quantitative and qualitative qualities, relying on the correlation as an electoral indicator of certain economic qualities such as the relationship between the number of seeds in the century and the recipes of the length of the century/cm (r = 0.984 * *), the weight of the century (g) (r = 0.977 * *), and other qualities.

Abstract: 

Microalgae represent a large, untapped source of new bioactive compounds (secondary metabolites) produced by some microalgae when they are subjected to harsh conditions (stress) in their environments such as: changes in salinity, temperature, nutrients, light, and ultraviolet radiation. Therefore, they must quickly adapt to new environmental conditions to survive. These secondary metabolites cannot be found in other organisms. Among these metabolites is astaxanthin (an active antioxidant) produced by the alga Haematococcus pluvialis, and its percentage in the samples study reached 7.86% of the dry weight of red cells. However, the antioxidant activity was higher in green cells extracted with ethanol compared to red cells, in which astaxanthin is in the form of esters of fatty acids.

Keywords: microalgae, astaxanthin, Haematococcus pluvialis, stress, fatty acids ester.

Abstract: 

The research was carried out at the Agricultural Scientific Research Center in Lattakia, within a 400 m² greenhouse planted with lettuce, during the fall of 2022, with the aim of studying the effect of using bio fertilization on some parameters of vegetative growth, quality and productivity of lettuce plants. The experiment was divided according to the randomized complete block design, where the experiment was included three transactions distributed as follows: 1.soil control without fertilization, 2.fertilization By injecting the soil with the bio fertilizer Beauveria bassiana (Bb).3. fertilizing the soil with the bio fertilizer Bacillus subtilis (Bs). The results showed that the bio fertilizers contributed to improving the vegetative growth characteristics of lettuce compared to the control. The highest stem weight was observed in the bio fertilizer (Bb) treatment (99.67 g) followed by the bio fertilizer (Bs) treatment (71 g) compared to the control (68 g). Bio fertilizer (Bb) was superior in terms of its effect on pulp weight (202g) compared to bio fertilizer (Bs) (97.3g) and the control (145g). Bio fertilizer (Bb) also contributed to an increase in root length (16.3 cm) compared to bio fertilizer (Bs) and control (12 and 12.3 cm), respectively. Bio fertilization contributed to an increase in the average representative surface area and the leaf surface index compared to the control with clear significant differences, and the highest value for them was recorded in the treatment of bio fertilizer ((Bs 7924 S2 / plant and 4.95). As for the productivity criteria, the two types of bio fertilizer contributed to improving the productivity parameters compared to the control, where the highest plant weight was recorded in the bio fertilizer treatment (Bb) (811.7 g), followed by the treatment of bio fertilizer (Bs) (641 g) compared to the control (583.7 g).The results also show the role of bio fertilizer in increasing productivity per unit area. The productivity per unit area in the bio fertilizer (Bb) treatment was 5.07 kg and in the bio fertilizer (Bs) treatment 4 kg The treatment with both types of bio fertilizer contributed to an increase in the percentage of dissolved solids (4.56% and 3.7%) for each of the bio fertilizers (Bs). ) and biofertilizer (Bb) respectively. The average percentage of dry matter percentage in the biofertilizer treatment (Bs) was 6.60% and in the bio fertilizer treatment (Bb) 5.37% compared to the control treatment 5.82%. Thus the results show the role of biofertilizers in plant growth as a source sustainable and continuous.
