Seed size is a component of grain yield and an important trait in crop domestication. To understand the mechanisms governing seed size in maize (Zea mays), we examined transcriptional and developmental changes during seed development in populations divergently selected for large and small seed size from Krug, a yellow dent maize cultivar. After 30 cycles of selection, seeds of the large seed po...

It has been proposed that abscisic acid (ABA) may stimulate sucrose transport into filling seeds of legumes, potentially regulating seed growth rate. The objective of this study was to determine whether the rate of dry matter accumulation in seeds of soybeans (Glycine max L.) is correlated with the endogenous levels of ABA and sucrose in those sinks. The levels of ABA and sucrose in seed tissue...

Large-panicle rice cultivars often fail to reach their yield potential due to the poor grain filling of inferior spikelets (IS). Thus, it is important to determine the causes of poor IS grain filling. In this study, we attempted to identify whether inferior grain filling of large panicles is restricted by superior spikelets (SS) and their physiological mechanism. SS were removed from two homozy...

This paper presents and evaluates a novel method for projecting a three-dimensional volumetric 6-connected object onto a 2D view using seed filling in the view space. Resampling a 6-connected volume by ray casting produces a new 6-connected volume, provided that the sampling rate is high enough. This new volume can be projected by a 3-dimensional seed filling algorithm. We implement and evaluat...

The goal of this study was to observe the impact of agro-management practices like, irrigation and nutrition on two pea (Pisum sativum) cultivars named Climax and Meteor at Horticultural Research Area, U.A.F. Growth parameters like Main stem Length (cm), number of leaves per plant, leaf Area (cm), number of pods per plant, length of pod (cm) number of seeds per pod and reproductive attributes l...

in order to study the effect of irrigation on fatty acid composition, oil and protein content of sunflower cultivars included azargol, allstar, alison and euroflor, an experiment was conducted at experimental field of the agricultural faculty of bu-ali sina university in 2007. treatments were arranged on split plot based on randomized complete block with three replications. the irrigation treat...

in order to evaluate the effects of drought stress at different phenological stages on growth indices of chickpea (cicer arietinum l.) cultivar jam, an experiment was carried out at the research greenhouse of faculty of agriculture, ferdowsi university of mashhad, using a completely randomized design with four replications. drought stress was applied by preventing irrigation until the soil mois...

Water deficits during seed filling often decrease seed size in soybean (Glycine max L.). The physiological basis for this response is not known but may result from direct effects of low seed water potential (Psi(w)) on the seed filling process. To determine whether low Psi(w) occurred in reproductive tissues of soybean, we monitored the water status (Psi(w), Psi(s), and Psi(p)) of leaf, pericar...
