Untapping root system architecture for crop improvement
Roots are the first organ to sense water deficit, and at the same time they extract virtually all those mineral nutrients from soil that are consumed by humans. Soil resource acquisition under challenging conditions such as drought is a primary limitation on plant productivity, resulting in low yields and thus food insecurity in the poorest countries. Indeed, in overall global agriculture, drou...
متن کاملPreparation of the root canal system
The key factor in the development of pulpal inflammation and apical periodontitis is the presence of bacteria [42]. It has been widely accepted that bacteria and/or their products are the main aetiological factors in the initiation and progress of these diseases [10]. Consequently, the central focus of root canal treatment has been directed towards the elimination of bacteria and their substrat...
متن کاملUltrasonic root-end preparation. Part 1. SEM analysis.
Preparations of apical cavities in resected root ends using rotary burs, with and without citric acid rinse, and ultrasonic tips were compared based on the presence or absence of superficial debris and smear layer. Three groups of 20 extracted teeth each were prepared as follows; I, a size 010 round bur was used to prepare an apical cavity 2-3 mm down the long axis of the root; II, treatment as...
متن کاملSpatial and temporal distribution of the root system and root nutrient content of an established Miscanthus crop
Although a high biomass yield is obtained from established Miscanthus crops, previous studies have shown that fertilizer requirements are relatively low. As little information on the role of the Miscanthus roots in nutrient acquisition is available, a study was conducted to gather data on the Miscanthus root system and root nutrient content. Therefore in 1992, the root distribution pattern of a...
متن کاملRoot - knot nematode ( Meloidogyne ) management in vegetable crop 1 production : the challenge of an agronomic system analysis
15 Root-knot nematodes are a growing concern for vegetable producers, because chemical 16 nematicides are gradually disappearing. Alternative techniques based on agronomic practices 17 are needed to solve the problem. This review analyzes the most recent studies related to these 18 techniques and their combinations and identifies the most effective ones. Based on an 19 agronomic point of view, ...
