“…The high leaf cytokinin content in DI during rewatering was beneficial for the increase in leaf P n compared with DT, WI, and WT. Cytokinin plays a promotional role in photosynthesis (Kobayashi et al, 2012 ; De Moura et al, 2017 ). The occurrence of high P n in DI compared with DT during rewatering led to compensatory growth as corn growth after rewatering was mainly involved in the fast photosynthetic organic matter accumulation.…”

“…The cytokinins have been implicated as critical determinants of nitrogen sink strength in the shoots, which drive nitrogen transport from the soil via roots (Aiken & Smucker, 1996). Active transport of nutrients required for photosynthesis and carboxylase activity are also influenced by cytokinins (de Moura et al, 2017). There are many other soil factors such as pH, bulk density, physical obstacles and neighbouring roots that influence hormonal production in roots for plant growth regulation.…”

The root system is vital for anchorage, mobilizing water and nutrients and symbiosis with soil microbes, which influence adaptation and crop performance. However, root traits are not widely used in crop variety development because root phenotyping is difficult and there is limited understanding of the genetics of root traits. The available genetic variation and emerging root phenotyping and genotyping technologies present opportunities for integrating root traits in breeding. Selection efficiency for root traits can be enhanced by integrating shovelomics, digital imaging, crop modelling and gene sequencing systems. Therefore, the objectives of this review are to discuss critical root traits and their vital functions, genetic variation present for root traits, opportunities and challenges in root phenotyping and integration of genomic tools in breeding for improved root systems. The information presented in the paper will guide crop breeders in developing a new generation of crop varieties with desirable yield and root traits.

“…(PBZ) [(2RS, 3RS)-1-(4chlorophenyl)-4,4-dimethyl-2-(1,2,4-triazol-1-yl)pentan-3-ol] is triazole capable of inhibiting cytochrome P450 dependent mono-oxygenases and, consequently, biosynthesis of gibberellins [11]. The changes in plant hormonal balance caused by triazole, such as elevated levels of cytokinins and abscisic acid, can interfere with foliar gas exchange and photosynthetic pigment content [12][13][14][15].…”

The use of shading and paclobutrazol in coffee plants can be an important cultivation strategy to mitigate the negative effects of high solar radiation and atmospheric temperature. Therefore, the levels of photosynthetic pigments and foliar gas exchanges of young coffee plants submitted to doses of paclobutrazol were evaluated, in environments with artificial light restriction. Five experiments were performed: one in full sunlight and four in artificially shaded environments with black polyethylene meshes at 20%, 40%, 60% and 80% levels of light restriction. In each of these environments, an experiment was carried out, consisting of five treatments, defined by the application of paclobutrazol via substrate, at doses of 0, 10, 20, 30 and 40 mg of active ingredient per plant. Joint analysis of experiments and analysis of variance of the regression were made, for the study of levels of shading and doses of paclobutrazol. The light restriction optimized the photosynthetic apparatus of the plants, mainly at levels close to 60%, and considerably favored leaf gas exchanges of arabica coffee. The application of paclobutrazol in the studied dosages resulted in little or no effect on photosynthetic pigment contents and did not influence leaf gas exchanges of coffee plants.
