The aim of this study was to investigate the climate change impacts on some factors affecting rainfed wheat growth such as effective rainfall, planting date and length of growing season in four stations located in Chaharmahal and Bakhtiari province. Firstly, it is necessary to predict future (2046-2065) climatic conditions. For this purpose, the output of HADCM3 general circulation model was us...

Introduction Plant architecture is determined by both the genetic basis of the plant (e.g. Wang and Li, 2006) and the effects of environmental factors (e.g. Evers et al., 2006). It can be described in terms of the dynamics of buds, with the fate of buds depending on their relative positions in space and time (Buck-Sorlin and Bell, 2000). The variation in architecture is obvious in wheat plants ...

To investigate the effects of salicylic acid on wheat by foliar spraying at various doses. An experiment in pots with three replications was carried out India during rabi season 2021-2022. Plant treated spray tillering, extension, and heading stages, concentrations 0.5mM, 1mM, 2mM. The results reveal that sprays 1mM 2mM aim to maintain shoot length under drought stress conditions. As concentrat...

Introduction The red:far-red ratio (R:FR) is a key variable in many biological processes from basic ones such as the response of phytochrome to more integrated ones, such as tillering or weed competition. Accurate estimation of the red:far-red ratio of plant organs in field condition is an important issue to be able to integrate the increasing knowledge on phytochrome-driven processes from cell...

abstract in order to identify the plant parasitic nematodes of potato fields, 55 soil samples and 60 infested tuber samples were collected from different fields in khorasan razavi province during 2005-2006 . soil samples were washed and nematodes were extracted by centrifugal flotation technique. according to de grisse, the extracted nematodes were fixed and transferred to glycerin. baermann fu...

Plant parasitic nematodes remain a major challenge to crop production that has hitherto received minmum research attention in sub-Saharan Africa. This paper gives the diversity of nematode genera and species associated with cereal crops and indicates the possibility of nemadode population build up due to production intensification especially in soils with high sand content. Twenty-two nematode ...
