background: with regard to the importance of preconception conditions in maternal health and fertility, preconception risk assessment makes treatment trends and pregnancy outcome more successful among infertile couples. this study has tried to investigate preconception risk assessment in infertile couples. materials and methods: this is a descriptive analytical survey conducted on 268 subjects,...

To evaluate the inoculation effect of potassium releasing, phosphate solubilizing and nitrogen fixing bacteria on the fruit quality of tomato, an experiment based on randomized complete block design with 9 treatments and 3 replications has been conducted. In this experiment, tomato (super chief cv.) seedlings of the in the treasury cultivation with single and combined treatments of the potassiu...

The hormone levels of auxin and gibberellin were studied in monoecious cucumber plants treated with growth regulators e.g. 2-chloroethylphosphonic acid (ethrel), gibberellic acid (GA3) and maleic hydrazide (MH). The studies were conducted at Vegetable Crops Research Programme, National Agricultural Research Centre Islamabad, Pakistan during 2003 and 2004. The greatest increase in female flower ...

In order to investigate the effect of urea and Azocompost on economic yield, nitrogen use efficiency (NUE) and radiation use efficiency (RUE) of wild majoram, a factorial experiment was conducted based on randomized complete block design with three replications at Yazd and Mashhad, Iran, during 2012-2013 growing season. Four urea levels and four Azocompost levels (to provide 0, 40, 80 and 120 k...

Air-dried flower heads of 20 Finnish tansy genotypes were extracted with petroleum ether and analyzed using GC-MS. A total of 55 volatile compounds were detected, and 53 were identified. Of the tansy genotypes studied, 15 were well defined and five were mixed chemotypes. Complete linkage analysis differentiated the populations into six clusters. The most frequently found monoterpene was camphor...

The multiple regulatory pathways controlling flowering and flower development are varied and complex, and they require tight control of gene expression and protein levels. MicroRNAs (miRNAs) act at both the transcriptional and post-transcriptional level to regulate key genes involved in flowering-related processes such as the juvenile-adult transition, the induction of floral competence and flo...

introduction sunflower (helianthus annuus l.) is one of the most important oil crops in the world. iran is climatically regarded as an arid and semi-arid region in the world, where the lack of precipitation and its inappropriate distribution, high temperature and extensive evaporation makes the irrigation the main way for meeting plants water demand. hence, studying the effect of irrigation on ...
