Vegetative tillering plasticity modulates agronomical optimum plant density in winter wheat
… L.), this concept becomes complex due to the tillering trait and its phenotypic variance due to the interaction between genotype and environment (G × E). In this scenario, phenotypic plasticity is an insightful crop ecology perspective to understand G × E. Our objectives were to explore the …

Tillering and carbohydrate content of orchardgrass as influenced by environmental factors
… to study the effect of environmental factors on tillering, growth, and carbohydrate content of orchardgrass. Tillers of one genotype were studied with several variable factors (light, temperature, moisture,. nitrogen, and/or defoliation) in each of four experiments. Factorial treatment …

Physiological aspects associated with mixed-nitrogen-induced increases in growth and tillering of wheat
… (mixed N nutrition) enhances growth and tillering of wheat. However, despite the potential benefits to productivity, limited information is available on the physiological basis for this response. Thus, the overall goal of this work was to determine the physiological aspects associated …

Studies on the factors influencing inhibition of lateral buds and branches
… and light are shown to be major factors in tillering of ryegrass and in addition that high nitrogen levels alone induce tillering in an apparently specific manner. This is in contrast to corresponding light treatments where such specific effects did not occur. The dynamics of the protein and …

Phenology, canopy development, biomass and grain yield of annual canarygrass (Phalaris canariensis L.)
… with FLN, it was negatively correlated with tillering cessation and its duration was shortened with late SDs. In wheat and oat, the start of stem elongation was relatively less affected by SD and tillering cessation was more related to the % of intercepted radiation by the canopy. In …

Exploring variation in water use efficiency in barley (Hordeum vulgare L.) among wild and circadian mutant varieties, and its impact on responses to drought
… produced better yield components (such as tillering) than elite varieties despite lacking targeted breeding. Meanwhile, phenotypic responses of the wild barleys were compared with the drought-tolerant variety, Bowman, under water stress conditions at germination and at tillering. Drought is …

Influence of timing of nitrogen application on yield and nutrient uptake of winter wheat (Triticum aestivum L.)
… N applications at G.S. 3.0 induced excessive tillering which was reflected in the higher number of tillers per m². Excessive tillering also resulted in increased lodging occurrence and reduced the harvest index. Increases in grain yield with split applications were attributed to greater …

Genotypic differences in lodging and Mechanical strength in stalks and Peduncles of Pearl millet (Pennisetum glaucum (L.) R. Br.)
… traits except stalk crushing strength, yield, tillering and peduncle length. Unlike millet increased peduncle length in sorghum had no effect on either stalk or peduncle lodging. Rind thickness and diameter were important in imparting strength to stalks and peduncles. The range of correlations …

Natural genetic variation and gene expression patterns underlying lateral shoot (tiller) development in barley (Hordeum vulgare L)
… that correlations between tiller development (tillering) and factors previously shown to influence tiller development, like photoperiod response and spike row-type, varied depending on environment and genetic background. Furthermore, no major trade-offs existed between tiller number and other …

Barley growth, physiology, and forage quality as influenced by defoliation and water stress
… (CP) concentration of Asni and Tamallalt at tillering, increased cell-soluble concentration of all cultivars at anthesis except Tamallalt. In the second study, defoliation reduced tiller number, plant height, and water-use efficiency (WUE), but did not affect water potential (WP), solute …

Crescimento vegetativo e rendimento agrícola da cana-de-açúcar sob cultivo irrigado
… irrigation influencing plant height and tillering of sugar cane variety RB92579, while the diameter of the stem is insensitive to these treatments. Crop yield and water use efficiency have opposite behavior, where on one side, farm income is increased with increased irrigation, while the …

Optimising durum wheat yield and quality
… with a total of six N treatments applied early (tillering) and late (flag leaf emergence) during crop development. At the dryland Darfield site, grain yield increased from 3.5 to 5.5 t/ha following 150 kg N/ha applied at tillering compared with increases from 4.5 to 7.0 t/ha at the irrigated …

Growth of pasture species in the shade in relation to alder silvo-pastoral systems : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy (Ph.D.) in Pastoral Science, Institute of Natural Resources at Massey University, New Zealand
… 14% PAR (heavy shade). Shade also affected the tillering ability of pasture species. Under heavy shade, cocksfoot (Dactylis glomerata L.) produced more tillers per plant than the other grass species examined. Perennial ryegrass (Lolium perenne L.) had the lowest tillering in heavy shade. Under …

Compactação do solo: efeito no perfilhamento e na produção de fitomassa fresca e seca de Brachiaria decumbens
… tillers. The succession of cuts induced shoot tillering of the rosette stem and not with the production of smaller tillers, resulting in lower height of plants and phytomass production. The consumption of water decreased with the succession of cuts and was greater with higher compression. The …

Red rice competition and control in cultivated rice
… red rice plants/sq m. Jasmine, a tall, vigorous tillering, mid-season cultivar was more competitive with red rice. With the exception of Cocodrie grown red rice free, no benefit existed from increasing the seeding rate above 190 plants/sq m. Another study examined the effect of permanent flood …
