Waxy wheat has unique end-use properties; however, its production is limited due mainly to its low grain yield compared with non-waxy wheat. In order to increase its grain yield, it is critical to understand the eco-physiological differences in grain filling between the waxy and non-waxy wheat. In this study, two waxy wheat and two non-waxy wheat c...

A rice (Oryza sativa L.)–wheat (Triticum aestivum L.) rotation system is the primary cereal planting system in China, especially in the middle and lower reaches of the Yangtze River (YR). Understanding dry matter (DM) accumulation, partitioning, and remobilization in high-yielding wheat is essential to realize high and stable yield in this area. A...

Nitrogen (N) is one of the most important impact factors on development and growth of wheat. In this study the effects of nitrogen use efficiency on quantity and quality of grains were studied by agronomic management of N fertilizers on spring wheat (Triticum aestivum L.) grown under field conditions for two years. The experiments were performed at...

... The overexpression of GBSSI in the present study supports the previous results that may be the accumulation of high amylose; this is because GBSSI plays an important role by elongating the a-amylase chain, which ultimately increases the resistant starch content [35]. Amylose content increased by the overexpression of GBSSI in wheat and rice; while the silence of this gene or null mutants produced waxy and partial waxy wheat with a low amount of resistant starch [34,36,37]. Decreasing the activity of SSs, SBEs, and isoamylase helps to increase the content of resistant starch in wheat. ...
... The reasons for the differences in the results of the present study may be related to the nitrogen application rate and soil nutrients supply capacity. Previous studies have found that the distribution and translocation of dry matter were affected by many factors, for example, varieties, climatic conditions, planting patterns and field management practices (Arduini et al., 2006;Fang et al., 2010;Liu et al., 2020a,b;Weichert et al., 2017), where water and fertilizer supply are the main human factors affecting dry matter distribution and post-anthesis dry matter translocation (Ding et al., 2016). In the present study, irrigation and fertilization had highly significant effect on t max , V max , D and V (P < 0.01), which indicated that irrigation and fertilization influenced the period and rate of aboveground dry matter accumulation. ...
... Among the various methods of N application, deep placement, use of super granules and foliar spray of N fertilizer can enhance the recovery of applied N fertilizer [17]. Two to three split applications of N usually during the growing season, rather than a single, large application prior to planting, are known to be effective in increasing NUE and yield [104,105]. The amount of nitrogen fertilizer to be applied is varied depend on soil type, crop type, variety response, water availability and other sources of nutrients. ...
