Transplanting has been the most widespread planting technique for rice production in Asia. It is estimated that more than 85% of rice production in china, and almost 100% in Northeast China adopted transplanting. The healthy and vigorous seeding can reduce thetransplanting shock’ and is the most important for final yield formation. The large root diameter, long root length, large surface area a...

this study was conducted to investigate the effects of applying deficit irrigation on aboveground biomass, leaf area and root biomass for maize hybrid 704 single-cross. experimental treatments included 4 different irrigation levels, 5 growth stages with three replicates in a completely randomized factorial statistical design. aboveground biomass, leaf area and root biomass in 4 longitudinal sec...

AIM To evaluate ex vivo the accuracy of two electronic apex locators during root canal length determination in primary incisor and molar teeth with different stages of physiological root resorption. METHODOLOGY One calibrated examiner determined the root canal length in 17 primary incisors and 16 primary molars (total of 57 root canals) with different stages of root resorption based on the ac...

in order to determine the effect of different irrigation intervals on some morphophysiological traits of basil (ocimum basilicum l.), an experiment was conducted as factorial based on randomized complete block design with three replications under greenhouse conditions during 2010. treatments included five irrigation intervals with 4, 8, 12, 16 and 20 days intervals and two ecotypes of basil (gr...

The effects of two water regimes (well-watered condition or drought stress) on root length,root surface area and root volume were tested on two peanut genotypes (the drought-resistantvariety HuaYu 22 (HY22) and the drought-sensitive variety HuaYu 23 (HY23)), measured 101days after sowing. The roots were sampled from the upper (0–40 cm) and deeper (40–100 cm)soil layers. Root diameter was measur...

in order to study the effect of different water potential on anethum graveolens l. an experiment was conducted. this study was carried out based on completely randomized design with three replications. in this experiment, morpho-physiological characteristics were assessed under hydroponic. stress was established with peg 6000, and drought potentials were: 0 (control), -1.5, -2, -2.5 and -3 bar....

introduction: the aim of this study was to evaluate the accuracy of two electronic apex locators (smarpex and novapex) in detecting apical perforation. materials and methods: after access cavity preparations, the working length was determined by the first examiner before and after perforation with a stereomicroscope by introducing a k-file size 10 into the canal and size 25 k-file up to the per...

To test direct and indirect effects of glomalin, mycorrhizal hyphae, and roots on aggregate stability, perspex pots separated by 37-μm nylon mesh in the middle were used to form root-free hyphae and root/hyphae chambers, where trifoliate orange (Poncirus trifoliata) seedlings were colonized by Funneliformis mosseae or Paraglomus occultum in the root/hyphae chamber. Both fungal species induced s...
