to study the effect of planting date on morphological characteristic, yield and essential oil content of achillea millefolium sub sp millefolium.l., an experiment in a randomized complete blocks design (rcbd) with four treatments including four planting date (6 july, 1 august, 7 september and 7 october) in four replications was conducted. during the growing stage and at the end of experiment pe...

Abstract Field studies were conducted to assess the efficacy of physical weed management Palmer amaranth in cucumber, peanut, and sweetpotato. Treatments arranged a 3 × 4 factorial which first factor included treatment method electrical, mechanical, or hand-roguing control second consisted treatments applied when was approximately 0.3, 0.6, 0.9, 1.2 m above crop canopy. Four wk after (WAT), ele...

Flowering plants exhibit one of two types of inflorescence architecture: indeterminate, in which the inflorescence grows indefinitely, or determinate, in which a terminal flower is produced. The indeterminate condition is thought to have evolved from the determinate many times, independently. In two mutants in distantly related species, terminal flower 1 in Arabidopsis and centroradialis in Ant...

Tomato is an important crop and hence there is a great interest in understanding the genetic basis of its flowering. Several genes have been identified by mutations and we constructed a set of novel double mutants to understand how these genes interact to shape the inflorescence. It was previously suggested that the branching of the tomato inflorescence depends on the gradual transition from in...

the genus ocimum belonging to lamiaceae is considered as one of the most economical medicinal plants throughout the world. it is used in medicinal tea, and essential oil production, in spices, as vegetable, and also as a pot herb. the aim followed in this study was to evaluate the genetic diversity of 38 native populations collected from different geographical origins of iran along with two for...

Inflorescence brassicas, such as broccoli and cauliflower, rich in fiber vitamins, are widely consumed Brazil, present an average production of 23 t ha-1. Despite this demand, the quality seedlings both species is one main factors that limit production. Thus, objective study was to evaluate cauliflower seedling emergence different substrates, using irrigation method named Deep Film Technique (D...

volatile components of three parts of pimpinella tragium vill. (umbelliferae family) from iran were investigated qualitatively and quantitatively for the first time. essential oils were isolated by hydro-distillation from stems plus leaves, inflorescence and seeds of p. tragium individually. the plant materials were collected from polour (northeast of tehran province). the yields of the stems p...
