In order to investigation effect of hexaconazole in some morpho- physiological traits of Althaea officinalis in drought stress, the experiment was conducted factorial in the base of complete randomized design with four replications in greenhouse of Islamic Azad university of Neyshabur branch in 2012- 2013. Treatments were drought (50%) and control (100%) field capacity and sparying of hexaconaz...
In order to investigate genetic diversity and heritability of some morphological traits in five bread wheat (Triticum aestivum L.) cultivars, two separate experiments were conducted based on randomized compeletly blocks design (RCBD) with 3 replications under stress and normal conditions. The results showed that differences between cultivars were significant for the majority of traits in both c...
This experiment was conducted to evaluate the effects of salt stress on some agro-physiological traits in ten varieties of bread (Triticum aestivum L.) and durum (Triticum turgidum L.) wheats in seedling stage. A greenhouse experiment was carried out as a split plot experiment based on a completely randomized design with four replications in hydroponic condition. Different agronomic and physiol...
Improving the drought tolerance of barley varieties through the integrated efforts of plant biotechnology and conventional breeding is an important objective in barley breeding. One hundred and fifty eight doubled haploid lines of barley were mapped with 50 SSR and 93 AFLP markers. Agronomic traits such as early growth vigor, plant height, peduncle length, extrude of spike from flag leaf, spike...
drought preconditioning (dp) is a method of irrigation with low frequency and longer duration, to extend the root system and suppress drought damage in plants. in the present study, the effect of dp for 30 days on increasing tolerance to drought stress in two turfgrass species, creeping bentgrass (agrostis stolonifera cv.palustris) and tall fescue (festuca arundinacea cv. greystone) was investi...
in order to study the effects of different sowing dates by some of companion crops on the weeds control, morphological traits and yield of corn sc 504, a field experiment was carried out of research field at tabriz university during 2010 growing season. treatments were arranged in a factorial experiment using randomized complete blocks design with three replicatins. factors was include four lev...
In tropical dry forests most plants are deciduous during the dry season and flush leaves with the onset of the rains. In Costa Rica, the only species displaying the opposite pattern is Bonellia nervosa. To determine if seasonal changes in light availability are associated with the leaf and reproductive phenology of this species, we monitored leaf production, survival, and life span, as well as ...
One of the most important limiting factors in cultivation of strawberry in greenhouses during winter season is short day-length. An experiment was conducted to evaluate the effect of end-of-day red light on growth characteristics, yield and fruit quality of strawberry (cv. Queen Elisa) in a completely randomized design with 4 treatments in winter of 2013. Strawberry plants were exposed to red l...
identification of morphological, phenological and yield characteristics of genotypes is important in order to collect necessary information for available varieties and as a result selection of one or more specific traits. in this study, 73 kabuli chickpea genotypes from pulses seed bank of research center for plant sciences, ferdowsi university of mashhad, were planted in irrigated conditions a...
