Leaf shape is one of the key determinants of plant architecture. Leaf shape also affects the amount of sunlight captured and influences photosynthetic efficiency; thus, it is an important agronomic trait in crop plants. Understanding the molecular mechanisms governing leaf shape is a central issue of plant developmental biology and agrobiotechnology. Here, we characterized the narrow-leaf pheno...

Dicranophyllum gallicum Grand'Eury is described by means of a morphometric analysis of eighty two samples from various old and new localities in western and central Europe. Stem, leaf cushions, leaf scars, leaves, axillary structures and potential seeds are described in detail, and discussed in comparison to earlier studies. The encountered variability in size and structure is shown to be highe...

In the present investigation was carried out to find out the impact of Triadimefon(TDM) and hexaconazole (HEX) triazole fungicides on the leaf anatomy of Radish (Raphanus sativus L.) The plant was treated with one litre of aqueous solution containing 20 mg -1 triadimefon (TDM) and 20mg -1 hexaconazole (HEX) on 23,35 and 53, days after sowing (DAS) by soil drenching. The plants were harvested on...

in order to evaluate the effects of different levels of water and plant density on yield, yield components, morphological and physiological characteristics of a new corn hybrid (ksc 500), an experiment was carried out in 2006 in karaj area. the experimental design was split plot based on randomized complete blocks design with three replications. main plots were three irrigation levels: 75%, 100...

This study was conducted to evaluate the response of Iranian promisinglate blooming almond genotypes to deficit-irrigation stress on GN15 rootstock. One-year old plants subjectedto three deficit-irrigation, including moderate and severe stress (soil water potential, Ψsoil = -0.8 and -1.6 MPa, respectively) and a control treatment (Ψsoil= -0.33 MPa), were applied for six weeks to five grafting c...

Leaf is an important organ for photosynthesis and transpiration associated with the plants’ growth. Through study of leaf phenotype, it physiological characteristics produced by interaction morphological parameters environment can be understood. In order to realize assessment spatial morphology leaves, a method based on three-dimensional stereo vision was introduced extract shape information, i...

Leaf morphology in maize is regulated by developmental patterning along three axes: proximodistal, mediolateral, and adaxial-abaxial. Maize contains homologues of many genes identified as regulators of leaf development in other species, but their relationship to the natural variation of leaf shape remains unknown. In this study, quantitative trait loci (QTLs) for leaf angle, leaf orientation va...
