The use of irrigation in the production of vegetables in the eastern part of the United States has shown a very rapid increase in the past 4 or 5 years. Irrigation not only increases the total yield, but also in many cases, the quality of the crop produced is improved as well. Physiologists are interested in learning if such differences in quality are largely of a physical nature or if there ar...

Perchlorate (ClO) has been detected in edible leafy vegetables irrigated with Colorado River water. The primary concern has been the ClO concentration in lettuce ( L. var. L.). There has been a limited number of studies on ClO uptake, but the interactive effect of other anions on ClO uptake is not known in detail. We conducted a greenhouse ClO uptake experiment using two types of lettuce (icebe...

At present, much effort is put into increasing the efficiency of cultivation systems for greenhouse vegetables. There are many options to manage plant growth factors in a greenhouse. For example, supplemental light can be given, even directed at specific plant parts. Functional-structural modelling is expected to help exploring different cultivation and plant manipulation regimes in order to op...

The consumption of diets formulated with Cruciferae vegetables, e.g., cauliflower, cabbage, and Brussels sprouts, has been shown to result in a stimulation of the intestinal and hepatic microsomal enzyme systems in rats. This study was designed to determine if this increase in intestinal and hepatic microsomal enzyme activity affected the hepatic response to polybrominated biphenyls (PBB). Afte...

BACKGROUND Little is known about how affordability of healthy food varies with community characteristics in rural settings. We examined how the cost of fresh fruit and vegetables varies with the economic and demographic characteristics in six rural counties of Texas. METHODS Ground-truthed data from the Brazos Valley Food Environment Project were used to identify all food stores in the rural ...

Okra is an important species of vegetable grown in Turkey and around the world. Root-knot nematodes cause serious yield losses vegetables. Twenty-six cultivars okra were obtained from Aegean Agricultural Research Institute 2002. Resistance this to nematode was determined changes induced with infestation on plant morphology macro- micronutrients leaves measured. The experiments conducted complet...

This research analyses the longitudinal relationships between household food insecurity (very low and low food security) experiences and children's consumption (servings/week) of fruit, green salad, carrots, potatoes, and other types of vegetables. Using a panel of 5,670 children aged 10-13 years who were first observed in spring 2004 and then again in spring 2007 at age 13-16 years, the main f...

OBJECTIVES To examine the association of timing of introduction and frequency of fruit and vegetable intake during infancy with frequency of fruit and vegetable intake at age 6 years in a cohort of US children. METHODS We analyzed data on fruit and vegetable intake during late infancy, age of fruit and vegetable introduction, and frequency of fruit and vegetable intake at 6 years from the Inf...

This study reports the modeling of three categories of ineffective vegetable parenting practices (IVPP) separately (responsive, structure, and control vegetable parenting practices). An internet survey was employed for a cross sectional assessment of parenting practices and cognitive-emotional variables. Parents (n=307) of preschool children (3-5 years old) were recruited through announcements ...
