The effects of day temperature (DT), night (NT), and length (NL) were evaluated on the flowering responses heat-tolerant heat-sensitive poinsettia ( Euphorbia pulcherrima Willd. ex Klotzsch) cultivars Orion Red Prestige Red, respectively. Plants placed under 60 DT × NT NL treatments that consisted three (20, 24, 28 °C), four (16, 20, five (10, 11, 12, 13, 14 hours) for first 17 days experiment....

ABSTRACT Karnal bunt of wheat is caused by the fungus Tilletia indica, which partially converts kernels into sori filled with teliospores. Despite minor overall yield and quality losses, the disease is of considerable international quarantine concern. Plant development stages reported susceptible to infection vary considerably. A study was designed to better define the susceptibility period by ...

Meteorological factors are one of the important that determine maize kernel weight and grain nutritional quality. Analyzing influence meteorological before after anthesis on quality components is great significance for improving corn yield Therefore, five different hybrids conducted continuous experiments from 2018 to 2021 were selected in this study, explore response growth periods, quantify l...

The water resource shortage in North China Plain is an increasing threat to the sustainabilityof wheat (Triticum aestivum L.) production. A two-year field experiment was conducted toexamine the effects of two supplemental irrigation (SI) methods on wheat flag leaf senescence,chlorophyll fluorescence and grain yield. The following field treatments were conducted:no irrigation (W0); SI with 60 mm...

Timely harvest is critical to achieve maximum seed viability and vigour in agricultural production. However, little information exists concerning how to reap the best quality seeds of Leymus chinensis, which is the dominant and most promising grass species in the Songnen Grassland of Northern China. The objective of this study was to investigate and evaluate possible quality indices of the seed...

Development of cotton (Gossypium hirsutum L.) squares (i.e. floral buds with bracts) is fundamental for yield formation. A 2-year field study was conducted to determine dry weight (DW) accumulations of cotton leaves, floral bracts and floral buds, and the changes in concentrations of non-structural carbohydrates (hexoses, sucrose and starch) in these tissues during square ontogeny as affected b...

Improving the efficiency of resource utilization has received increasing research attention in recent years. In this study, we explored the potential physiological mechanisms underlying improved grain yield and water-use efficiency of winter wheat (Triticum aestivum L.) following organic fertilizer application. Two wheat cultivars, ChangHan58 (CH58) and XiNong9871 (XN9871), were grown under the...

Cytokinins (CKs) are thought to play important roles in fruit development, especially cell division. However, the mechanisms and regulation of CK activity have not been well investigated. This study analysed CK concentrations and expression of genes involved in CK metabolism in developing tomato (Solanum lycopersicum) ovaries. The concentrations of CK ribosides and isopentenyladenine and the tr...

Drought stress occurring during the reproductive growth stage leads to considerable reductions in crop production and has become an important limiting factor for food security globally. In order to explore the possible role of drought priming (pre-exposure of the plants to mild drought stress) on the alleviation of a severe drought stress event later in development, wheat plants were subjected ...
