the tuberose cut flower is much less longevity in postharvest. the less vase life due to stress of deficit carbohydrate and quick respiration on inflorescence. in this study, effectiveness factors, sucrose, cacl2, al2so4 and re-cut the stems. in current research two separate experiments were arranged as a factorial based on compeletly randomized design. the first experiment were added to all ex...

a greengouse experiment was conducted to evaluation of salinity stress on growth parameters of two olive cultivars during 2013-2014 at agricultural and natural resources research center of tehran. in the experiment, effects of five levels of irrigation water salinity including 0, 4, 8, 12 and 16 ds.m-1 were evaluated on ʻzardʼ and ʻmissionʼ olive cultivars under soilless culture. data showed th...

WequantiÞed thedensity-dependent effects of herbivory by thepsyllidBoreioglycaspis melaleucae Moore on the senescence of expanding and fully expanded leaves from two chemical variants (chemotypes) of the invasive tree Melaleuca quinquenervia (Cav.) S. T. Blake. Foliar chlorophyll content (OD) and percent nitrogen were not inßuenced by leaf age classes and chemotypes. In contrast, increases in t...

Arbuscular mycorrhizal (AM) fungi are well known symbiotic microorganism found to improve the growth of host plant by mobilizing immobile nutrients, mainly phosphorus, from soil. However, effect AM on depends percentage colonization, whereas it is not clear that percent mycorrhization impacts fungal spore abundance inoculum. Therefore, current investigation was conducted know Glomus intraradice...

to evaluate the effect of different levels of drought stress on some physiological parameters in strawberry, potted experiment involing strawberry cultivars  ‘marak٫ , ‘camarosa٫ and ‘gaviota٫ was conducted during summer 2009. the experiment consisted of three drought stress levels in three replications. the experimental arrangement was a factorial one, based upon a randomized complete block de...
