In order to identify drought tolerant strawberry (Fragaria ananassa Duch.) cultivars and investigate some of their morphological, quantitative and qualitative characteristics, a research was conducted as split plots based on randomized complete blocks design with three replications under greenhouse conditions. Deficit irrigation stress was considered as the main plot factor at 4 levels (control...
This study was carried out to evaluate the effects of Gibberellic acid and Paclobutrazol respectively on promote flowering and vegetative growth reduction in strawberry in order to enhance production. Gibberellic acid and paclobutrazol are plant growth regulators. Gibberellic acid can act as a promoter while, paclobutrazol act as an inhibitor. Gibberellic acid at 100 mg/l, 30 and 90 days and pa...
This research was carried out to investigate the response of agronomic traits, yield and yield components of pumpkin (Cucurbita pepo L.) to phosphate solubilizer biofertilizer at different levels of phosphorus (P) fertilizer. The experiment was factorial, based on randomized complete blocks design with three replications. Treatments included two levels of phosphate solubilizer biofertilizer (in...
Leaves are the plant's solar panel and food factory, and leaf traits are always key issues to investigate in plant research. Traditional methods for leaf trait measurement are time-consuming. In this work, an engineering prototype has been established for high-throughput leaf scoring (HLS) of a large number of Oryza sativa accessions. The mean absolute per cent of errors in traditional measurem...
At least since Simpson (1944), if not before, evolutionary biologists have been fascinated by the tempo or rate of evolutionary change through time. Studies of changes in evolutionary rate have grown into a major component of research on macroevolution using phylogenies (e.g. Collar, O’Meara, Wainwright, & Near, 2009; Mahler, Revell, Glor, & Losos, 2010). A wide variety of hypotheses have been ...
We report the results from a search in Super-Kamiokande for neutrino signals coincident with the first detected gravitational-wave events, GW150914 and GW151226, as well as LVT151012, using a neutrino energy range The Astrophysical Journal Letters, 830:L11 (6pp), 2016 October 10 doi:10.3847/2041-8205/830/1/L11 © 2016.

کاربرد مداوم علف‌کش‌های بازدارنده‌استیل کوآنزیم‌آ کربوکسیلاز برای کنترل علف‌های هرز باریک‌برگ‌های مشکل‌ساز در مزارع گندم کشور منجر به بروز مقاومت در 5 گونه از علف‌های هرز باریک‌برگ شده است. اخیرا بیوتیپ‌هایی از علف هرز یولاف وحشی مقاوم به علف‌کش کلودینافوپ پروپارژیل، ستوکسیدیم و پینوکسادن مورد شناسایی قرار گرفته که دارای شاخص مقاومتی بین 31/1 تا بیش از 63/50 در برابر بازدازنده های ACCase بودند....
in order to evaluate the effects of biofertilizer on soybean (glycine max l.) seed vigor that produced under water deficit condition and related traits, an experiment was conducted in a factorial layout based of complete randomized block design with four replications at the research greenhouse of aboureihan campus- tehran university, iran. experimental treatments were include biofertilizer (see...
BACKGROUND AND AIMS In maize (Zea mays), early flowering date, which is a valuable trait for several cropping systems, is associated with the number of leaves per plant and the leaf appearance rate. Final leaf number depends upon the rate and duration of leaf initiation. The aims of this study were to analyse the genotypic variation in the response to temperature of leaf appearance rate and lea...
Taro (ColocasiaesculentaL. Schott) is a perennial root crop that belongs to Araceace family. It is widely cultivated as a staple food in Africa, Asia and pacific Islands. Despite its importance, there is limited information on many aspects of the crop. In order to obtain data that can support improved and sustainable taro production, a field trial was conducted to study the effects of ...
