In wheat, tillering and water-soluble carbohydrates (WSCs) in the stem are potential traits for adaptation to different environments and are of interest as targets for selective breeding. This study investigated the observation that a high stem WSC concentration (WSCc) is often related to low tillering. The proposition tested was that stem WSC accumulation is plant density dependent and could b...

BACKGROUND AND AIMS Genotypic variation in tillering can be caused by differences in the carbon supply-demand balance within a plant. The aim of this study was to understand and quantify the effects of genotype on tillering as a consequence of the underlying internal competition for carbohydrates. METHODS Five sorghum hybrids, derived from inbred lines with a common genetic background and wit...

Tillering is a core constituent of plant architecture, and influences light interception to affect plant and crop performance. Near-isogenic lines (NILs) varying for a tiller inhibition (tin) gene and representing two genetic backgrounds were investigated for tillering dynamics, organ size distribution, leaf area, light interception, red: far-red ratio, and chlorophyll content. Tillering ceased...

a randomized complete block design with three replications was performed in rice research institute of iran, rasht in 2008, to find the effect of supplement foliar application of nitrogen and potassium on ’daylam‘ hybrid rice grain yield, its components and grain protein percentage. foliar application of 20 kg nitrogen (5 percent n) and 15 kg potassium (3 percent k2o) in different pre-anthesis ...

The release of nitrogen by roots of intact spring wheat plants into the soil and other losses, mainly of volatile N, have been investigated in two subsequent years from tillering until maturation, by use of a new technique for plant labelling with N. Plants were at first labelled by growing them in a N nutrient solution until tillering and then after thoroughly washing the roots with distilled ...

The experiment was conducted at the Agronomy field of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during August, 2008 to January 2009 to find out the optimum plant spacing and number of seedling per hill in relation to tillering and dry matter accumulation of transplanted rice plant. The experiment was carried out with three plant spacings (S =15 cm × 20 cm, S = 20 cm × 20 cm and S...

Tillering determines the plant size of sorghum (Sorghum bicolor) and an understanding of its regulation is important to match genotypes to prevalent growing conditions in target production environments. The aim of this study was to determine the physiological and environmental regulation of variability in tillering among sorghum genotypes, and to develop a framework for this regulation. Diverse...

The effects of irrigation water salinity (12 dS m−), imposed at maximum tillering (35−40 days after sowing, DAS) or booting (50−60 DAS) or grain filling (75−85 DAS) stage of wheat, on growth and yield of the crop was demonstrated. The experiment comprised four treatments – I1: irrigation by fresh water (FW) at all three growth stages (control), I2: irrigation by saline water (SW) at maximum til...

Tillering is an important trait in monocotyledon plants. The switchgrass (Panicum virgatum), studied usually as a source of biomass for energy production, can produce hundreds of tillers in its lifetime. Studying the tillering of switchgrass also provides information for other monocot crops. High-tillering and low-tillering mutants were produced by ethyl methanesulfonate mutagenesis. Alteration...
