Objective: Castor (Ricinuscommunis L.) is an industrial oilseed that belongs to the family Euphorbiaceae. Castor is believed to be originated in East Africa probably Ethiopia. Although Ethiopia is known as a primary diversity for castor the knowledge on nature and extent of variation of the indigenous germplasm is limited. The present test was conducted to study the nature and extent o...

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...

The aerodynamics of wind pollination selects for an intimate relation between form and function in anemophilous plants. Inflorescence architecture and floral morphology vary extensively within the Poaceae, but the functional implication of this variation remains largely unknown. Here we quantify associations between floret, culm, and inflorescence characteristics for 25 grass species in Kananas...

As knowledge of the gene networks regulating inflorescence development in Arabidopsis thaliana improves, the current challenge is to characterize this system in different groups of crop species with different inflorescence architecture. Pea (Pisum sativum) has served as a model for development of the compound raceme, characteristic of many legume species, and in this study, we characterize the ...

The distribution of carbon (C) into whole grapevine fruiting cuttings was investigated during flower development to determine the relative contribution of inflorescence and leaf photoassimilates in the total C balance and to investigate their partitioning towards other plant organs. A (13)C labelling procedure was used to label C photoassimilates by leaves and inflorescences in grapevine. Inves...

Duration of various stages of inflorescence differentiation and hormone levels in apical buds eventually decide the harvest time, flower uniformity and quality of ornamental plants. The progress in inflorescence differentiation process in the chrysanthemum cultivar ‘Jingyun’ can be divided into nine stages. Following short day induction, it took 4d to reach the growing point hypertrophy stage, ...

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...

in order to evaluate the allelopathic potential of sunflower (helianthus annus l.) organs on germination and growth of dodder (cuscuta compestris l.), series studies were conducted in three separate experiments; as factorial based on completely randomized design (crd) with three replications for each experiments. first experiment was conducted in petri dishes and consisted of sunflower organs a...
