TL;DR: In this paper, a two-year field experiment was conducted in a randomized complete block using two fertilization techniques (broadcast and deep placement by mechanical side-dressing fertilization) and three controlled-released nitrogen fertilizers (CRNFs) (sulphur-coated urea (SCU), polymercoated Urea (PCU), and a bulk blended mixture (BBF)).

TL;DR: An improvement in the lodging resistance of high-yield rice populations could be achieved by the suitable plant height with the optimum configuration of internodes, namely, shorter basal stems and a longer peduncle, and by increasing stem stiffness, which was primarily attributed to higher proportions of structural carbohydrates and greater plumpness of the leaf sheaths.

TL;DR: It is suggested that sucrose and several hormones act as signal substances and play a vital role in grain filling by regulating enzyme activities and gene expression and therefore, IS grain filling is restricted by SS, which limit assimilate supply and plant hormones, leading to poor grain filling of IS.

TL;DR: Shading decreases the stem mechanical strength of japonica rice by decreasing non-structural carbohydrate, sucrose, lignin, and cellulose accumulation in culms, and this results suggest that gene expression involved in the reduction of lign in and cellulosity in both sclerenchyma and parenchyma cells result in poor stem strength and higher lodging risks.

TL;DR: An improvement in the lodging resistance of japonica rice plants could be achieved by reducing the length of the lower internodes, decreasing the inner culm diameter and developing a thicker mechanical tissue.
