to investigate the effects of different salinity levels of nacl on germination of safflower (cv. esfahan 24) seeds under three different incubation methods, a factorial experiment was carried out based on a complete randomize design with three replications. salinity levels were 0, 5, 10, 15 and 20 dsm-1 (nacl) and incubation methods were sandwich method, and using petri dishes with open or clos...

Seedling damage during transportation often occurs in seedling that using container. The use of mahogany seeds sown on cocopeat as bare root is expected to answer the problems from nursery planting site. purpose this study was determine effect Mahagony age (on medium nursery) and length time delay (bare-root seedling). This used a completely randomized design (CRD) factorial with two factors, n...

objective: in order to investigate effects of gibberlic acid (ga3) and sprimidin poly amine on germination of three cultivars of wheat under salinity stress. methods: the experiment was conducted as factorial based on completely randomized design with four replicates in agronomy and plant breeding laboratory of agricultural department of islamic azad university, varamin-pishva branch in spring ...

Seedling vigor, which is controlled by many quantitative trait loci (QTLs), is one of several important agronomic traits for direct-seedling rice systems. However, isolating these QTL genes is laborious and expensive. Here, we combined QTL mapping and microarray profiling to identify QTL genes for seedling vigor. By performing QTL mapping using 82 backcross inbred lines (BILs) of the Koshihikar...

Gregarious flowering of bamboo species impacts ecosystem properties and conservation, but documentation of these periodic events is difficult. Here, we compare the characteristics of flowering sites and un-flowered patches of an arrow bamboo (Fargesia qinlingensis) in the Qinling Mountains, China, over a 5-year period (2003-2007) after a mast flowering event (2003). We examined flowering culm a...

In order to investigate the effects of priming methods on the improvement of seed germination indices and seedling growth of Lallemantia (Lallemantia Iberica) under different salinity levels, two factorial experiment in a randomized complete block design were carried out in the seed technology laboratory of Agricultural Sciences and Natural Resources University of Khuzestan in 2018-2019. In the...

Objective: In order to investigate effects of different concentration of gibberlic acid (GA3), kentin and Putrescinepoly amine, on germination of three cultivars of wheat under salinity stress. Methods: The experiment was carried out as factorial based on completely randomized design with four replicates in laboratory of Agronomy and Plant Breeding, department of agriculture in Islamic Azad Uni...
