Capsicum annuum L. commonly known as chilli provides dietary fibers, minerals and vitamins. In this study, three different chilli cultivars commonly named as Dandi, Ghotki and German were studied for the determination of physico-chemical properties, antioxidant activity and metal content. German showed maximum nutritional components as compared to Ghotki and Dandi such as TA (0.43 %), TDS (1.95 g/l), TSS (1.29 °Brix) and TSC (1108.72 mg/100 g). Dandi showed higher TPC (6286.60 mg/100 g) and TFC (258.88 mg/100 g) with significant antioxidant activity through DPPH (37.27 % inhibition) and RPA (1134.80 mg/100 g). Fe was found in sufficient amount among chilli cultivars and metals accumulation was within the standard safe limits. Bangladesh J. Bot. 50(3): 507-513, 2021 (September)

Capsicum Annuum L

Resistance of the Hungarian pepper (Capsicum annuum L.) cultivar "Gre.ygo" to Tohamoviruses has been investigated. All plants of the population of Greygo proved to be resistant to tobacco mosaic and tomato mosaic viruses (TMV, ToMV), both represent the pepper pathotypes Po of Tohamoviruses. Individuals of Greygo, however, were found to be susceptible to pathotypes P12 and P123 of pepper mild mottle virus (PMMV). When inoculated with the XM isolate of dulcamara yellow fleck virus (DYFV, pathotype P1) the population of Greygo segregated in resistant and susceptible plants. These results as well as inoculations of the progenies of three TMV resistant plants clearly showed, that besides the resistance allele Li the cultivar Greygo possesses also an another allele. This allele, provisionally marked by L2g behaves like to the allele L2 characteristic to Capsicum frutescens cv. . Tabasco. Determination of the identity of the allele L2g to the allele L2 needs further genetic and pathological informations. Relations between the Tohamoviruses pathogenic to pepper and the alleles of the resistance gene L are outlined for the discussion.

The aim of this study was to compile DRIS (Diagnosis and Recommendation Integrated System) norms and sufficiency ranges for pepper grown in greenhouses and the determination of the variation in DRIS norms and sufficiency ranges during the different phenological stages of the crop. The DRIS norms and sufficiency ranges were constituted by 367 leaf samples of Capsicum annuum L. which were collected in different phenological stages of the crop (flowering (FL), fruiting (FT), fruit development (FD), and harvesting (HV)). Two sufficiency ranges were developed; one including all leaf samples and the other considering the leaf samples by phenological stages ((FL) (44), (FT) (96), (FD) (100), and (HV) (127)). Furthermore, 10 DRIS norms and CV were calculated from N, P, K, Ca, and Mg. Two ratios of them were calculated in FL (N/P and N/K), two in FD (N/P and Ca/N) and one in HV (N/P) showing low CV, meaning, according to DRIS norms, the essential role of these nutrients in the crop nutrition. Moreover, the sufficiency ranges computed by all database were: N (34–56), P (1.9–4.3), K (30–51), Ca (12–33), and Mg (4.0–15) (mg g−1 DW), respectively. The data obtained in this experiment highlighted the importance of the sensitivity (low CV) of nutrient in the phenological stages such as happened with N.

Significant Difference

The aim of our examination was to evaluate the correlations between the normalized difference vegetation index (NDVI) and yield, as well as to examine the possibility of yield estimation basedon NDVI in a seasoning paprika population. Significant correlations were observed during the examination of the correlation between NDVI and yield. Furthermore, it was concluded that yield can be estimated with a 6.6–8.3% mean error based on the regression equations. No significant difference was shown between the error of estimations performed with various regression types and that of the estimations performed at various dates. For this reason, the identification of the optimum estimation method and the determination of the optimum date for estimation call for further examinations.
