broccoli (brassica oleracea l. cv premium crop) florets were packaged using two types of polymeric films (polyethylene, ld & polypropylene cast) and then stored at 1?c for 18 days to study the effect of passive and active map (1.5%o2+7.5%co2) on preservation of quality and nutritional value as compared to non-wrapped control florets. during storage, weight loss, rate of ethylene production, qua...

background and objectives: safflower (carthamus tinctorious l.) florets contain valuable red and yellow pigments and are used in food, textile dying, and pharmaceutical industries. red carthamine pigment is formed from a yellow precursor, precarthamine, through an oxidation reaction at the end of flowers' maturation stage. the present study was conducted to find out the most effective procedure...

BACKGROUND Understanding the spatial distribution of stunting and underlying factors operating at meso-scale is of paramount importance for intervention designing and implementations. Yet, little is known about the spatial distribution of stunting and some discrepancies are documented on the relative importance of reported risk factors. Therefore, the present study aims at exploring the spatial...

Broccoli contains high levels of bioactive molecules and is considered a functional food. In this study, postharvest treatments to enhance the concentration of glucosinolates and phenolic compounds were evaluated. Broccoli whole heads were wounded to obtain florets and wounded florets (florets cut into four even pieces) and stored for 24 h at 20 °C with or without exogenous ethylene (ET, 1000 p...

in this study, effect of exogenous putrescine on maintaining postharvest quality and antioxidant compounds of two broccoli cultivars, ‘general’ and ‘liberty’ during cool storage were investigated. broccoli branchlets were treated with 0.5, 1 and 1.5 mm putrescine. distilled water was used as control. treated florets were put into polyethylene bag and transferred to storage with 0°c and 90% rh. ...

background: limited data are available indicating associates of stunting among iranian c hildren. objective: this study was conducted to investigate determinants of stunting in first grade primary school children of tehran in 2007. methods: in this case‑control study, 3147 school children were selected by multistage cluster random sampling method from 5 districts of tehran. anthropometric measu...

Wheat yield depends on the number of grains per square metre, which in turn is related to the number of fertile florets at anthesis. The dynamics of floret generation/degeneration were studied in contrasting conditions of nitrogen (N) and water availability of modern, well-adapted, durum wheats in order to understand further the bases for grain number determination. Experiments were carried ou...

BACKGROUND Stunting continues to be a child public health concern in many African countries, including South Africa. This study uses data from the Birth to Twenty study, held in Johannesburg, to investigate a range of household-level socioeconomic and social support predictors of stunting in children aged less than 30 months. DESIGN Logistical regression models were constructed using a concep...
