Twenty three cultivars of carrot (Daucus carota L.) roots consisting of fifteen local and eight exotic cultivars were analysed for various chemical constituents including dry matter, total soluble solids (TSS), -carotene, total and reducing sugars, phenolics, phosphorus, zinc, manganese, copper, iron, sodium potassium and ash. In addition other characteristics such as days to maturity, root weight and length, flesh thickness, core diameter, number of forked and cracked roots per plot have been studied. Yellow carrots were found to have maximum root length, water soluble carbohydrates and minimum -carotene content. The exotic cultivars were found to have higher TSS content than the local cultivars, while the latter cultivars had higher mineral contents than the former. However, on the average, dry matter content, total water soluble sugars, reducing and non-reducing sugars were found to be greater in exotic cultivars than in local ones, but -carotene, phenols and phosphorus contents were greater in local cultivars. A significant positive correlation between -carotene content, ash percentage and days to maturity was observed. A wide variation in chemical constituents and plant characteristics was observed indicating a high genetic variability in the material under study. 相似文献

Fresh red fruits of twelve chilli (Capsicum annuum L.) varieties had higher dry matter, crude protein, ascorbic acid, phosphorous, zinc and copper contents than the corresponding mature green fruits. Varietal variations with respect of these constitutents were also observed. 相似文献

Summary The study was undertaken to evaluate the relative efficiency of anther culture and chromosome elimination (by crosses with maize) techniques of haploid induction in intergenotypic triticale and triticale × wheat hybrids. For this, 15 triticale × wheat and 8 triticale × triticale F1 hybrids were subjected to anther culture and were also simultaneously crossed with the `Madgran Local' genotype of maize (Zea mays L.) to induce haploids through the chromosome elimination technique. The haploid embryo formation frequency through the chromosome elimination technique was significantly higher in both, triticale × wheat (20.4%) and triticale × triticale (17.0%) F1 genotypes, as compared to the calli induction frequencies through anther culture (1.6 and 1.4%, respectively). Further, four triticale × wheat and three triticale × triticale F1 genotypes failed to respond to anther culture, whereas, all the F1 genotypes formed sufficient number of haploid embryos through the chromosome elimination technique with no recovery of albino plantlets. The haploid plantlet regeneration frequencies were also significantly higher through the latter technique in both triticale × wheat (42.7%) and triticale × triticale (49.4%) F1s as compared to anther culture (8.2 and 4.0%, respectively), where the efficiency was drastically reduced by several constraints like, high genotypic specificity, low regeneration frequency and albinism. The overall success rates of obtaining doubled haploids per 100 pollinated florets/anthers cultured were also significantly higher through the chromosome elimination technique (1.1% in triticale × wheat and 1.5% in triticale × triticale hybrids), proving it to be a highly efficient and economically more viable technique of haploid induction as compared to anther culture, where the success rates were only 0.2% and 0.1%, respectively. 相似文献

The effect of different levels of nitrogen N0 (0), N1 (60), N2 (80) and N3 (100) kg/ha and phosphorus P0 (0), P1 (32), P2 (48) and P3 (64) kg/ha on the nutrient composition of sweet pepper fruits was investigated. Dry matter content was found to increase at N0 level at highest concentration of phosphorus and as well as at P0 level at highest concentration of nitrogen. At P2 concentration, at different levels of nitrogen, the ascorbic acid content was more as compared to that at other levels of phosphorus. Protein content was found to increase with increasing nitrogen doses and was also found to increase at maximum dose of nitrogen with increasing concentration of phosphorus. Capsaicin content was found to be more at P2 level at different doses of nitrogen. The uptake of phosphorus by the pepper fruit was found to increase at N0 and N2 levels. Maximum uptake of phosphorus and dry matter content was observed at N0P3 levels. Maximum protein, ascorbic acid and capsaicin contents were found at N3P2 level. 相似文献

The fruits of two tomato varieties were analysed at five stages of maturity, viz. mature green, turning, pink, red and red
ripe, for some physico-chemical changes associated with fruit ripening. Fruit weight and size, pericarp thickness, drymatter,
ascorbic acid, sugars, protein, N, P, Zn, Fe, Mn and Cu contents were observed to increase with maturity and reached maximum
or near maximum at red stage. The acidity was maximum at turning or pink stage and then decreased to a minimum level at red
ripe stage. Varietal differences were present. 相似文献

Five white and seven red varieties of onion were analysed for dry matter, carbohydrates, total phenols, coloring matter, lachrymatory factor and pyruvic acid content. Percent dry matter varied from 10.66 to 14.80. Total water soluble sugars, reducing sugars and total phenols ranged from 41.50 to 74.00, 12.00 to 22.25, and 1.75 to 2.95 percent (on a dry wt basis), respectively. The lachrymatory factor and pyruvic acid content ranged from 8.00 to 27.25 mg/100g and 6.18 to 13.27 micro moles/g respectively on a fresh wt basis. Red varieties contained a higher phenolic content than white ones. Varieties with higher phenolic content also had a greater amount of coloring matter in the dehydrated onions. The variety Punjab-48 was considered to be most suitable for dehydration purposes. 相似文献

Phosphate-solubilizing fungal strains were isolated from organically managed soil and tested for their ability to solubilize rock phosphate (RP), ferric phosphate and aluminium phosphate. These strains were identified as Aspergillus tubingensis and Aspergillus niger based on internal transcribed spacer sequence analysis. A field study was conducted in two different seasons in organically managed soil to test the efficacy of two strains, A. tubingensis (PSF-4) and A. niger (PSF-7) on the yield and soil fertility. RP was amended at the rate of 59 kg P2O5 ha?1 to study the effect of RP on soil fertility. The maize was grown in rainy season (July–October 2011) and wheat in winter season (November 2011–April 2012). Plant heights, shoot and root dry biomass and phosphorous (P) uptake in roots, shoots and grains were significantly increased due to inoculation in both crops. The yield of maize and wheat were significantly increased when inoculated along with RP fertilization. Organic carbon, P levels and soil enzyme activities were significantly increased due to inoculation. Results of present study suggested that A. tubingensis and A. niger improved the crop yield and soil fertility of organic farm when inoculated with RP fertilization. 相似文献
