HIGHLIGHTS The number of flowers, the abortion rate, and fruits per flower cluster directly influence processing tomato yield. Deficient or excessive irrigation levels impair flowering increase flowers tomato. Irrigation management is essential for yield crops from Brazilian Cerrado.

This study aimed to analyze the genetic variability of 323 accessions of the Active Germplasm Bank (BAG) of Coffea canephora of the Institute for Research, Technical Assistance and Rural Extension of Espírito Santo (Incaper) using 38 quantitative phenotypic characters. The standardized average Euclidean distance between the accessions was estimated to generate a statistical distance matrix and,...

†Background and Aims Dimorphism among floral traits can evolve through variation in selection intensity between female and male performance, especially when sex functions are separated between flowers on a plant (monoecy), or between individuals (dioecy). In animal-pollinated species, male floral traits are predicted to be larger because competition for pollinators should favour larger displays...

introduction fertilizers are the key components which provide plant nutrients' needs in recent years (omid jangir & sing, 1996; kapoor et al., 2007). in many cases, using chemical fertilizers has different negative environmental effects such as soil, water and air pollution, which increase environmental hazardous and production costs (jangir & sing, 1996; kapoor et al., 2007). biological activi...

background & aim: german chamomile is one of the most important medicinal plants. so, assessment of genetic diversity and relationship among the traits are very essential in chamomile breeding programs. determination of the best indirect selection criteria for genetic improvement of essence percent and dry flower yield of german chamomile (matricaria chamomilla l.) populations was investiga...

Flowering plants have developed many ways to arrange their flowers. A flowerbearing branch or system of branches is called an inflorescence. The number of flowers that an inflorescence contains ranges from a single flower to endless flower-clusters. Over the last centuries, botanists have classified inflorescences based on their morphology, which has led to an unfortunate maze of complex botani...

Concerns related to the rise of disposition to the application of the medicinal plants throughout the world have gone up on their cultivation and production processes. In order to study the effect of planting seasons on morphological traits, yield, oil content and oil composition of black cumin, an experiment was conducted under field condition in Mashhad, Iran in 2012-2013 as a randomized comp...

introduction: more plains of iran are located in arid and semi-arid regions and so agricultural production systems depend heavily on water. recently, the reduction of water resources has become a serious threat for crop production such as cotton planting. therefore, application of low irrigation methods can be an appropriate method to cope with mentioned condition. in addition, it is vital to i...
