“…These findings are reported by those of Garcia et al [35,36]who reported that cultivar and nitrogen fertilizer forms influenced cereal tillering ability. The effect of tillering ability on grain formation emphasizes its contribution to the attained yield as observed by Yan et al [37] and Li et al [38].…”

“…Changes in the rate of leaf appearance or phyllochron (i.e. thermal time required between the appearance of two successive leaves; Cao and Moss ) influence the dynamics of tiller appearance (Hay and Kirby ), which in turn affects yield, through the determination of spike number per plant (García del Moral and García del Moral , Elhani et al. , de San Celedonio et al.…”

“…). In wheat and barley several authors have reported a counterbalance between the rate of tiller appearance and the rate of tiller mortality, as the more tillers initiated the fewer tillers survive (García del Moral and García del Moral , Berry et al. , Salvagiotti and Miralles ).…”

The aim of this study was to analyse (i) the crop attributes that determine flowering time (i.e. final leaf number, FLN; and phyllochron, Phy), (ii) the dynamics of tiller appearance and (iii) the synchrony between leaf and tiller appearance in wheat and barley plants exposed to waterlogging. Two experiments were carried out in pots, in which wheat and barley cultivars were exposed to five waterlogging treatments, during different periods throughout the crop cycle, from emergence to maturity. The appearance of leaves and tillers on the main stem was measured twice a week in labelled plants. Waterlogging from emergence to flag leaf appearance significantly delayed time to flowering. The delay was greater when waterlogging occurred at the beginning of tillering, lengthening the period from emergence to flowering 24 % (13–15 days) in barley and 10–15 % (6–10 days) in wheat, as compared to control. Phy was the main attribute explaining the delay in flowering, as FLN was not altered. Waterlogging during the early stages of development reduced tiller appearance rate (TAR) in both species, but this effect was partially counterbalanced by a lengthening of the tillering phase, so the effect on final tiller number at maturity was limited. In conclusion, the exposure of wheat and barley to waterlogging during early stages of development delayed time to flowering and reduce TAR in both species. Waterlogging during more advanced crop stages produced slight effects on tillering dynamics, which would indicate that waterlogging affected structure generation more than mortality.

“…These resulted in long-day conditions and shortening of the tillering period. Del Moral and Del Moral (1995) showed that the maximum number of tillers was inversely related to the temperature during tillering. This means that higher temperatures are shortening the tillering period resulting in a lower number of tillers formed.…”

“…Thus, under changing environmental conditions, there is a need to understand yield formation and the possibilities by which barley genotypes are able to compensate the negative impacts of weather conditions and obtain stable yields under increasing variability of the environment (Del Moral and Del Moral 1995).…”

The processes of stand structure and yield formation of spring barley were studied under different weather conditions and crop management. The multifactorial small-plot trials focused on the combined effect of variety, sowing density and nitrogen nutrition were carried out in two years with contrast weather conditions for yield formation (2011 and 2013). Evaluation of the above-ground biomass and the segmentation of tillers into three groups was conducted in four growth stages (BBCH 25, 31, 39 and 75). The performed analyses confirmed that for effective use of inputs and high yield, it is important to create a sufficient number of strong tillers at the beginning of vegetation. In year with low proportion of strong tillers at the end of tillering (2013), the differentiation of tillers is delayed and their productivity decreases. In this year therefore, yield formation is shifted from the number of spikes to the number of grains in a spike. The comparison of barley genotypes revealed that high yield plasticity can be obtained especially in the variety Bojos, which is able to compensate effectively the changes in spike number by increased grain number in a spike. This variety is also able to create a high proportion of strong tillers even under unfavourable conditions. This knowledge could help to improve the breeding and management strategy in spring barley for the expected weather conditions in the near future, especially higher temperatures in early spring.
