Flow cytometric measurements of nuclear DNA content were performed using ethidium bromide as the DNA stain (internal standard, Hordeum vulgare 'Ditta', 1C = 5.063 pg) in 25 samples belonging to nine diploid species and four varieties of Capsicum: C. chacoense, C. parvifolium, C. frutescens, C. chinense, C. annuum var. annuum, C. baccatum var. baccatum, C. baccatum var. pendulum, C. baccatum var...

Chilli pepper (Capsicum annum L) is being grown in diverse climatic conditions throughout India. Nonpersistent aphid transmitted viruses have been implicated as the major factor contributing to low yields of chilli pepper in India. A virus causing symptoms of mosaic mottling, vein banding, and leaf distortion of chilli was isolated from chilli growing areas of Karnataka and Tamil Nadu states of...

Dentre as hortaliças de destaque está o gênero Capsicum pertencente à família Solanaceae, que envolve pimentas (Capsicum spp.) e os pimentões annum). Os frutos C. chinense são caracterizados por uma grande diversidade, em termos cores, formatos pungência, podem ser suaves até extremamente pungentes. O objetivo do trabalho foi avaliar desenvolvimento plântulas variedades spp. cultivadas diferent...

Shades ranging from violet to black pigmentation in pepper (Capsicum annuum L.) are attributed to anthocyanin accumulation. High-performance liquid chromatography and mass spectrometry analysis of violet and black fruit tissue identified a single anthocyanin that was determined to be delphinidin-3-p-coumaroyl-rutinoside-5-glucoside. Leaf tissue of a black-pigmented foliage genotype contained th...

Genetic diversity and structure were analyzed in 10 accessions belonging to Banco Ativo de Germoplasma de Capsicum located at Federal University of Piauí in northwestern Brazil that receives pepper samples grown in community gardens in various regions and Brazilian states. Selections were made from seeds of C. chinense (4 accessions), C. annuum (5 accessions), and C. baccatum (1 accession). Sam...

The Thailand cultivar pepper 'phrik man bangchang' (Capsicum annuum var. acuminatum, Solanaceae) was originally cultivated in the Bangchang Subdistrict, Amphawa District in Samut Songkhram Province. The cultivated areas are limited; we verified its distribution in Thailand for in situ 'phrik man bangchang' genetic resource conservation. Samples were collected from the original cultivation area ...

Variability in the concentrations of the chemical constituents that contribute to fruit flavor in Capsicum chinense is poorly documented in the scientific literature. We surveyed fruit of 216 landraces and cultivated varieties of Capsicum chinense acquired from North, Central, and South America, and analyzed these for concentrations of the simple sugars sucrose, glucose, and fructose, and citri...

Vegetables are either consumed in the raw or cooked form. While in the raw state, most of the nutrients are retained, whereas any degree of cooking generally results in partial loss of nutrients and considerable changes in its sensory characteristics. This study is aimed at comparing the effect of different cooking methods namely, conventional (boiling), pressure cooking, and microwave cooking ...

The pericarp of Capsicum fruit is a rich dietary source of carotenoids. Accumulation of these compounds may be controlled, in part, by gene transcription of biosynthetic enzymes. The carotenoid composition in a number of orange-coloured C. annuum cultivars was determined using HPLC and compared with transcript abundances for four carotenogenic enzymes, Psy, LcyB, CrtZ-2, and Ccs determined by q...
