Effects of topping and non-topping on growth-regulating hormones of flue-cured tobacco (Nicotiana tabacum L.)—a proteomic analysis

Frontiers in Plant Science, 2023
IntroductionUntil now, the mechanism underlying the impact of topping on hormone regulation in tobacco plants remains unclear, and most studies investigating the hormone signaling pathways in plants rely on genes or transcriptional pathways.MethodsThis ...

Transcriptome analysis reveals key genes involved in the regulation of nicotine biosynthesis at early time points after topping in tobacco (Nicotiana tabacum L.)

BMC Plant Biology, 2020
Background Nicotiana tabacum is an important economic crop. Topping, a common agricultural practice employed with flue-cured tobacco, is designed to increase leaf nicotine contents by increasing nicotine biosynthesis in roots.

Evaluation of the Effect of Topping on Cannabidiol (CBD) Content in Two Industrial Hemp (Cannabis sativa L.) Cultivars

Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca: Horticulture, 2020
In order to define the finest cultivation practices for two of the most commercial hemp cultivars (‘Fedora 23’ and ‘Futura 75’) under the Mediterranean climate, the treatment of topping was applied in hemp crop in Central Greece.

Yields, growth and water use under chemical topping in relations to row configuration and plant density in drip-irrigated cotton

Journal of Cotton Research
Background Water deficit is an important problem in agricultural production in arid regions. With the advent of wholly mechanized technology for cotton planting in Xinjiang, it is important to determine which planting mode could achieve high yield, fiber

Effects of Spraying with Ethephon and Early Topping on the Growth, Yield, and Earliness of Cotton under Late-Sowing and High-Density Cultivation Modes

Agronomy, 2023
Late-sowing and high-density cultivation are typical cotton planting models that are widely applied in the Yellow River Valley of China. The model can easily lead to late maturity and reduced yields. Plant topping and ethephon spraying have been shown to
