Pistachio is one of the most important horticultural crops in Iran.  There is a unique role for amino acids in the plant response to stressful conditions, and special physiological role for Arginine (Arg) compared to other amino acids.  The effects of this compound were investigated on vegetative and reproductive characters of bearing pistachio trees of ‘Ahmad-Aghaei’. The experiments were done...

To determine the effects of drought stress, especially light on flower number in passion fruit, one-year-old fruit plants grown 7.5 L plastic pots were subjected to different soil water content treatments, namely wetness, drought, and heavy for two months. Average, maximum, minimum contents (v/v) 44, 47, 41% wetness treatment, 23, 40, 11% treatment 11, 33, 6% treatment. Flower decreased as stre...

effect of automobile pollution on the productivity of crocus sativus was studied for one year time period (october 2005-april 2006). the parameters which were analyzed viz total chlorophyll, carotenoids, leaf area, plant height, corm size, corm weight, corm yield, biomass, flower production, and length of stigma and style, showed a remarkable decrease as compared to control. total chlorophyll ,...

The balloon flower (Platycodon grandiflorum A. DC.) is a perennial flowering plant of the Campanulaceae family; it is the only member of the genus Platycodon. Information on the genetic diversity of balloon flower populations is of great importance for the conservation and germplasm utilization of this flowering plant. Twenty-two polymorphic microsatellite loci were developed and character...

Flowers are very diverse, with a large range in the size, number, color and morphology of the floral organs, differences that seem to reflect the adaptation of individual species to their mechanism of pollination. The study of the genetic basis of the generation of flower form has been greatly aided by a handful of model plant species, including Antirrhinum (Snapdragon), Arabidopsis and Petunia...

Corolla length is a labile flower feature and has strong implications for pollinator success. However, the phenotypic and genetic bases of corolla elongation are not well known, largely due to a lack of good candidate genes for potential genetic exploration and functional work. We investigate both the cellular phenotypic differences in corolla length, as well as the genetic control of this trai...
