In order to increase the structural performance of rotary tillage knife, a badger claw toe was selected as bionic prototype and optimization design knife carried out. The similarity between badger’s tiller is 0.7073 by fuzzy algorithm, shape goodness fit final mole’s digging shovel 0.9556 MATLAB. Using 3D modeling software NX10.0, we established three-dimensional model knife. Furthermore, use W...

Abstract Background Tiller number is a factor determining panicle and grain yield in wheat ( Triticum aestivum ). Auxin plays an important role the regulation of branch production. PIN-FORMED 1 (PIN1), auxin efflux carrier, tiller rice Oryza sativa ); however, little known on roles PIN1 wheat. Results Nine homologs TaPIN1 genes were identified wheat, which TaPIN1-6 showed higher expression stem...

Four rodent control techniques-sustained baiting (SB) with cournachlor. pulsed baiting (PB) with brodifacoum. a lethal electrified barrier (LEB), and a nonlethal electrified barrier (NLEB)-were evaluated on the experimental fann of the International Rice Research Institute (IRRI) in the Philippines. A fifth treatment (no experimental rodent control) was established for reference. Mean tiller da...

BIOFEEDBACK techniques are an effective way of controlling chronic anx­ iety without the aid of drugs. But just as effective. it seems, is learning how to relax. or simply sitting qu ietly in a room for 20 minutes each day. These surprising findings have emerged from a series of studies on anxiety conducted the Monash department of psychological ."edicine at Prince Henry's hospital by Dr John T...

Grasses produce tiller and panicle branching at vegetative and reproductive stages; the branching patterns largely define the diversity of grasses and constitute a major determinant for grain yield of many cereals. Here we show that a spatiotemporally coordinated gene network consisting of the MicroRNA 156 (miR156/)miR529/SQUAMOSA PROMOTER BINDING PROTEIN LIKE (SPL) and miR172/APETALA2 (AP2) pa...

ABSTRACT Perennial ryegrass (Lolium perenne) was inoculated with urediniospores of Puccinia graminis subsp. graminicola at four stages of reproductive tiller development. All developmental stages, from expansion of the penultimate leaf through anthesis, were equally susceptible to infection measured as number of pustules per total inoculated plant area. However, within each stage from boot thro...

We report the discovery and spread of a dwarf ecotype of Spartina alterniflora in San Francisco Bay. Relative to typical S. alterniflora, this dwarf ecotype has one-fifth the tiller height (∼21 cm), tenfold the tiller density (∼4000 tillers/m(2)), and is restricted to growth in the upper intertidal zone. Chromosome counts of the dwarfs are identical to typical smooth cordgrass (2n = 62), and sm...
