in recent years application of plant growth regulators especially growth retardants, has been significantly increased. trizols (paclobutrzol and trinexapac-ethyl) as the most effective and least harmful growth retardants, induce more dwarf and denser cover plants with both darker and thicker leaves.  therefore, an experiment based on completely randomized block design with 16 treatments and 3 r...

Many experiments have been carried out to alleviate the negative effect of drought stress and to obtain suitable growth under water deficient condition. Application of plant growth regulators (especially growth retardants) is one of the proposed methods. In a greenhouse experiment using a completely randomized block design with 4 replications at Kerman University Agricultural Department, the ef...

Many experiments have been carried out to decrease the negative effect of drought stress and obtain suitable growth under water deficit conditions. Application of plant growth regulators (especially growth retardants) is one of the proposed methods. This study was conducted to investigate the effect of Cycocel application on growth of two olive cultivars (Shengeh and Roghani) under water stress...

Pistachio is one of the economically important horticultural crops in Iran. The main pistachio-producing areas in Iran are located at the edge of the desert and are affected by soil and water salinity. Water and nutrient uptake by the root decreases under saline conditions. In this study, the effects of foliar growth regulators applied at different times on the nutrient uptake and leaf nutrient...

1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
