Auxin and cytokinin (CTK) play important roles in regulating the growth of rice tiller buds. Auxins inhibit bud growth and CTK, which are regulated by auxins, promote growth. However, little is known about the underlying molecular mechanisms. Here, we studied auxin/CTK regulation in Nanjing 44 rice, a japonica cultivar. After full heading, we cut off the roots and removed the panicles. The till...

Mature perennial ryegrass plants in pastures persist through the asexual reproduction of the tiller. Leaves are initiated from the flanks of the tiller stem apex. Generally, two leaves arc growing on a tiller at any one time. New tiller buds may arise from the axils of mature leaves depending on environmental conditions. Flowering results from a physiological change at the stem apex, which then...

Reproductive allocation is critically important for population maintenance and usually varies with not only environmental factors but also biotic ones. As a typical rhizome clonal plant in China's northern grasslands, Leymus chinensis usually dominates the steppe communities and grows in clonal patches. In order to clarify the sexual reproductive allocation of L. chinensis in the process of the...

Tiller angle is one of the most important components of the ideal plant architecture that can greatly enhance rice grain yield. Understanding the genetic basis of tiller angle and mining favorable alleles will be helpful for breeding new plant-type varieties. Here, we performed genome-wide association studies (GWAS) to identify genes controlling tiller angle using 529 diverse accessions of Oryz...

Taking the lubrication system of rotary tillage engine as research object, this paper makes a three-dimensional simulation study on oil flow characteristics in lubricating passage. The supply pump shall be greater than circulating required by to ensure cultivator. Lubrication is an important part reliability and durability key component achieve its performance pump. geometric model field tiller...

In order to improve the performance of tillage tool for straw incorporation in silty clay loam, a combined implement with plough and rotary tiller was designed. Its on power consumption investigated, types (CTSR CTDR) were compared traditional including sole type (SP DP), (RT), two-pass (SP+RT DP+RT) rice field experiment. The effect forward speed RT CTSR studied by DEM simulation. ratio covera...

A model which describes tiller density dynamics in bahiagrass (Paspalum notatum Flügge) swards has been developed. The model incorporates interrelationships between various morphogenetic and structural components of the sward and uses the inverse of the self-thinning rule as the standard relationship between tiller density and tiller weight (a density-size equilibrium) toward which tiller densi...

Operator performance on the tiller-motor system was investigated in a field survey and in a tracking simulator. Boat operators in Study 1 reported both control difficulties and discomfort, when using their tiller-motor system. Participants in Study 2 operated a tiller-motor simulator of a boat navigating a river over a 20 min period. Directional and speed control performance was found to be poo...
