abstract rosa damascena has attracted considerable attention in horticulture, biochemistry and in pharmacology because of the fragrance of the flowers and the high content of its bio-logically active substances. there is limited information available on factors controlling flower yield and its components. the present study reports an investigation on flower yield and the various factors affect...

In order to study the effect of water deficit stress and different nitrogen levels on flower yield, yield components and water use efficiency of Calendula officinalis L., an experiment was conducted as split plot based on randomized complete block design with three replications, at research field of Islamic Azad University, Birjand branch in 2009. In this experiment, irrigation treatments (irri...

The steppe peony (Paeonia tenuifolia L.) is an endangered medicinal plant species that occurs in Serbia three habitats, of which the Deliblato Sands richest. Based on results research conducted at 2023, it was found development flowering stems Paeonia not affected by slightly higher average winter temperatures. One hundred randomly selected plants were measured field, including height, girth, n...

The number of ovules per flower varies over several orders of magnitude among angiosperms. Here we consider evidence that stochastic uncertainty in pollen receipt and ovule fertilization has been a selective factor in the evolution of ovule number per flower. We hypothesize that stochastic variation in floral mating success creates an advantage to producing many ovules per flower because a plan...

in order to investigate the effect of high density and depth of planting on agronomic characteristic of saffron, a field experiment was conducted as a complete randomized block design with three replications in faculty of agriculture, ferdowsi university of mashhad, iran during two growing seasons of 2008-2009 and 2009-2010. treatments were six levels of high densities (8, 11, 13, 16, 19 and 21...

recently, biofertilizer application is growing to meet sustainable agriculture goals. the present experiment was designed to evaluate four nitrogen levels (0, 60, 90 and 120 kg n.ha-1) as main plots, two supernitroplus biofertilizer levels) with and without biofertilizer) as sub-plots on yield and yield components of three sesame cultivars (naz, oltan and varamin (as sub-sub-plots in a split-sp...
