Lutein Content

Lutein and &beta;-carotene contents in 32 samples of field peas with green (<I<ii</I>), yellow (I.) and orange cotyledons (<I>OrcOrc</I>) were determined. The highest lutein concentration ranging between 0.768 and 1.394 mg/100 g was found in varieties with green cotyledons (median 0.978 mg/100 g). Yellow cotyledons contained lower amount of lutein, median = 0.692 mg/100 g. Big variation in lutein content was found in tested breeding lines with orange cotyledons, only 4 lines showed higher lutein content in comparison with the lowest value found in green cotyledons. Content of &beta;-carotene in field peas with green cotyledons ranged between 0.1–0.2 mg/100 g. Field peas with yellow and orange cotyledons contain &beta;-carotene in 10 times lower concentration. 27 samples of garden peas were tested. Lutein content fluctuated between 0.471 and 1.524 mg/100 g with median = 0.791 mg/100 g. Year-to-year differences in 54% of all repeatedly tested samples shoved coefficient of variation lower than 10%. Coefficient of variation under 20% was found in 96% of repeatedly analysed samples. A strong correlation (<I>r</I> = 0.77, <I>P</I> < 0.01) between lutein and chlorophyll contents was found.

An experiment was conducted to standardize the predrying treatments with minimum loss to physicochemical characteristics of green peas (Pisum sativum L.) cv. Lincoln during drying process. In this study, moisture content (73%), TSS (15oB), chlorophyll content (28mg/100g) and ascorbic acid (54mg/100g) were recorded in green peas. Different predrying treatments used in this study for quality preservation of peas were T0, T1 and T2. From this study, it was concluded that Na2CO3, NaCl and sugars were responsible for the preservation of green color/ chlorophyll in peas during drying. On the basis of sensory evaluation T2 was found best among all because maximum green color was retained in this treatment. Therefore, it was further selected for physico-chemical analysis After drying there was decrease in moisture content (4%), chlorophyll content (17mg/100g) and ascorbic acid content (37.6mg /100g) while increase in TSS (22oB), reducing sugars (8.3%) and total sugars (20%) of peas. A rehydration ratio of 3:1 was observed for this treatment. This is a low cost technology for preservation of quality of peas. Dried peas can further be utilized for the preparation of various value added instant products round the year.

Pisum Sativum L

Compensation between carbon dioxide exchange rate per unit photosynthetic area (CER) and total photosynthetic area (TPA) of a plant was examined in field-grown pea (Pisum sativum L.). Eight near-isogenic lines of cv. Alaska, representing all possible phenotypes of the genes af (leaflets transformed to tendrils), st (reduced stipule area) and tl (tendrils transformed to leaflets), were examined. The CER was measured on the leaflets (AfAf), tendrils (afafTlTl) or minute leaflets (afaftltl). The TPA was significantly reduced by the st gene in AfAf types (normal leaflets) with an apparently associated increase in CER. The st gene also significantly reduced the TPA in afaf types but there was no associated increase in CER. Tendrils had a lower CER than normal leaflets and comprised 22% of the TPA of the semi-leafless (afafStStTlTl) type. Crosses were made between a semi-leafless pea and four normal-leafed types previously selected for high or low CER. The CER means (normal leaflets) of the F1 progeny showed variability which was related to parental values. This was also true for the CER means (tendrils) of the populations of semi-leafless F2 segregants showing that genetic variability for CER can exist in tendrils. In the F2, tendril CER was correlated negatively to stomatal resistance and positively to chlorophyll content and final shoot dry weight (biomass). Genetic improvement in CER may be important when a plant ideotype requires substantial reduction in TPA.Key words: Photosynthesis, pea, chlorophyll content, stomatal resistance, Pisum sativum

<p class="R-AbstractKeywords"><span lang="EN-US">The microbiological fertilizer Baikal EM-1 contains lactic acid bacteria, photosynthetic bacteria, nitrogen fixing bacteria, <em>Saccharomyces</em> yeasts and microbial cultivation media. </span><span lang="EN-US">The aim of the present study was to evaluate the impact of it on onion grown in controlled greenhouse conditions. </span></p><p class="R-AbstractKeywords"><span lang="EN-US">In summer 2014 two trials with this product were carried out on onions in greenhouse conditions. Before planting onion bulbs were soaked in water with added fertilizer and growth substrate was watered with the fertilizer according to the instructions of manufacturer. During the vegetation period plants were watered with the fertilizer several times. Identical treatment was performed with water in the control plots. Different treatment schemes and growth substrates (neutralized peat and substrate for vegetables) were used in both trials. The main difference of the used substrates was in the content of mineral nutrients that was higher in the substrate for vegetables. In the second trial additional fertilization with ammonium nitrate was applied three times during the vegetation period. At the end of the trials the yield of onion leaves was estimated, as well as the length of leaves and their chlorophyll content was measured. </span></p><p class="R-AbstractKeywords"><span lang="EN-US">At the first trial the obtained yield of onion leaves was increased by 6.4 % and in the second by 8.2 % due to treatment with Baikal EM-1 but these differences were not statistically significant in comparison to the control plots. In general, the fertilizer increased all other measured parameters as well, including average length of leaves by 4.6 % and 1.3 %, the chlorophyll content by 5.0 % and 1.5 %, in the first and second trial respectively, and percentage of onions developing leaves increased by 13.2 % in the second trial. Only the last parameter showed statistically significant differences in comparison to the control. Additionally the growth of the onion was more even in the control treatment. In conclusion, the microbiological fertilizer Baikal EM-1 gave positive impact on onions in greenhouse conditions.<em></em></span></p>
