to study the effect of plant density and planting pattern on iranian ox-tongue, an experiment carried out with two factors: planting pattern (square and rectangular pattern) and plant density (2, 4, 6, 8 plant m-2) in a factorial test performed based on rcbd in 3 replications during 2009-2010 in latmahalleh eshkevarat village in guilan province, iran. characteristics that measured included: dry...

The number of pods per common bean plant is a primary component of grain yield, which depends on the number of flowers produced and on the flower set. Thus, a larger number of flowers per plant would increase yield. Lines with inflorescences that had a large number of flowers compared to common bean plants now under cultivation were identified. We analyzed the genetic control of this trait and ...

abstract this reasearch was conducted to study the phenotypic diversity of thymus kotschyanus populations. seeds were collected from natural inhabitats (guilan, mazandaran, west azarbaijan, semnan and qazvin) and planted in qom reasearch station in 2007. a number of some such different morphological and phenological traits of the plants as plant,s height, leaf length, leaf width, oil content, i...

Vertical raceme or spike inflorescences that are bee-pollinated tend to present their flowers horizontally. Horizontal presentation of flowers is hypothesized to enhance pollinator recognition and pollination precision, and it may also ensure greater consistency of pollinator movement on inflorescences. We tested the hypotheses using bee-pollinated Corydalis sheareri which has erect inflorescen...

Plants often grow in clusters of various sizes and have a variable number of flowers per inflorescence. This small-scale spatial clustering affects insect foraging strategies and plant reproductive success. In our study, we aimed to determine how visitation rate and foraging behaviour of pollinators depend on the number of flowers per plant and on the size of clusters of multiple plants using D...

Epidendrum radicans is a food deceptive Batesian mimic of its sympatric model species Asclepias curassavica and Lantana camara. Theoretically, food deceptive orchids should be rare with small inflorescences (Johnson et al. 1993; Weins 1978) yet in San Luis, Costa Rica E. radicans grows in large monotypic stands with individuals sporting up to 12 open flowers per inflorescence. E. radicans might...

abstract tuberose is one of the most important cut flowers in iran and the world. in this experiment, effect of microelements fe, zn, cu and mn on inflorescence length, inflorescence bunch length, number and diameter of floret, diameter of inflorescence bunch and vase life of tuberose flowers were studied. this study was based on four separate completely randomized experimental design with four...

introduction with the continuous growth of world population, degradation and ecological imbalance throughout the world, there is a need to increase agricultural production and environmental protection measures. in this respect, efforts to supply nutrients to the environment are at the head of the programs. one of the ways to approach this goal is the use of intercropping systems (najafi & moham...
