background and objectives: hawthorn is a forest fruit tree which is grown in the temperate regions around the world. this plant is known as the most traditional herbal remedy for heart failure and cardiovascular disease in worldwide. this study has been conducted to investigate the genetic variability and classify hawthorn genotypes based on quantitative and qualitative characteristics of leaf...
growth traits, yield and fruit quality in ‘synda’ tomato were compared with those in tomatoes grafted onto either ‘king kong’ rootstock or onto their own rootstocks, (trained as single or double stem), and at two fruit thinning levels, of: no thinning or thinned to five fruits per truss. the data related to crop growth rate (cgr), relative growth rate (rgr), net assimilation rate (nar), leaf ar...
Background: The aim of this study was to clarify the relationship between the sexual reproduction and the resource allocation in a natural Polygonatum humile population grown in a temperate mixed forest gap. For this aim, the plant size, the node which flower was formed, the fruiting rate, and the dry weight of each organ were monitored from June 2014 to August 2015. Results: Firstly, in 3–13-l...
One of the requirements of a fruit harvesting robot is the ability to recognize and locate fruit from the leaf and branch portions; machine vision system is one of the methods used to detect the location of the fruit. This paper showed the development of a machine vision algorithm that would guide an apple harvesting hand prototype. The objectives of this study were to differentiate the fruit f...
BACKGROUND AND AIMS The mechanisms involving light control of vitamin C content in fruits are not yet fully understood. The present study aimed to evaluate the impact of fruit and leaf shading on ascorbate (AsA) accumulation in tomato fruit and to determine how fruit sugar content (as an AsA precursor) affected AsA content. METHODS Cherry tomato plants were grown in a glasshouse. The control ...
To evaluate the resistance of promising chickpea ecotypes to freezing temperatures, an experiment with eight promising cold tolerant chickpea was performed. The ecotypes consisting of 4301, 4322, 4360, 4361, 4366, 4380, 4715, 4816 along with a sensitive one (304) were sown in pots at natural conditions. All the chickpea ecotypes were exposed to freezing temp eratures at controlled conditions d...
in chapter one we will describe definitions and preliminary results to provide the global context of our own results to be presented in detail in the subsequent chapters in chapter two we consider degree-one maps of the circle and we study their rotation set. our main result in this chapter says that if the map is topologically mixing then its rotation interval is nontrivial (that is, not reduc...
In order to investigate the relationship between different traits with yield, an experiment was conducted on 16 tomato genotypes in randomized complete blocks design, with three replications. Twenty agronomical traits including plant height, stem diameter, number of shoots, plant weight, number of branches, number and dry weight of leaves, stems and roots, number of fruits per plant, fruit weig...
The pomegranate fruit is a good source of bioactive compounds. The present study has investigated the biochemical and sensory characteristics of the arils of four Iranian commercial pomegranate cultivars namely Malase Shirine Saveh (MSS), Malase Torshe Saveh (MTS), Alak Shirine Saveh (ASS) and Agha Mohammad Ali (AMA) for several developmental and ripening stages during 45–180 days after fruit s...
Automatic irrigation scheduling based on real-time measurement of soilless substrate water status has been recognized as a promising approach for efficient greenhouse irrigation management. Identification of proper irrigation set points is crucial for optimal crop performance, both in terms of yield and quality, and optimal use of water resources. The objective of the present study was to deter...
