Unlabelled: Viable pollen is crucial for fertilization, but pollen is generally highly susceptible to heat stress. A quick, reliable method for testing the heat-stress tolerance of pollen is needed to improve the heat-stress tolerance in plants, but current methods require considerable space and labor. In addition, many such methods only test tolerance to a single constant temperature, making it time-consuming to screen heat tolerance over a wide temperature range and to examine the dynamics of pollen viability at different temperatures.

The Geometric Series Hypothesis of Leaf Area Distribution and Its Link to the Calculation of the Total Leaf Area per Shoot of 'Aureostriatus'.

Plants (Basel)

December 2024

Co-Innovation Center for Sustainable Forestry in Southern China, Bamboo Research Institute, Nanjing Forestry University, #159 Longpan Road, Nanjing 210037, China.

Total leaf area per shoot () can reflect the photosynthetic capacity of a shoot. A prior study hypothesized that is proportional to the product of the sum of the individual leaf widths per shoot () and the maximum individual leaf length per shoot (), referred to as the Montgomery-Koyama-Smith equation (MKSE). However, empirical evidence does not support such a proportional relationship hypothesis, as was found to allometrically scale with , i.

Forage-grain ratoon rice (FG-RR) systems, integrating grain and forage production, promise a sustainable approach to enhance food security and livestock development in marginal regions where ratoon rice (T-RR) is traditionally cultivated. Here, we quantified zinc (Zn), copper (Cu), arsenic (As), and cadmium (Cd) concentrations in ratoon crop grains from 23 rice varieties at four mowing stages (heading, milk-ripening, dry-ripening, and full maturity) of the main crop. Early mowing at the milk-ripening stage significantly reduced As levels (16.

Article Synopsis
  • The Montgomery equation (ME) links leaf area to leaf length and width, with its proportionality influenced by leaf shape, represented by the Montgomery parameter (MP).
  • A study sampled 840 leaves from six trees to analyze various leaf shape indices, discovering that larger trees have more ovate leaves while DBH did not significantly impact other indices like width to length ratio.
  • Results indicate that the MP (0.6466) remains consistent regardless of tree size, validating the ME for calculating leaf area at both the individual tree level and across multiple trees with minimal error when compared to a power-law equation.

Effect of sorghum flour-containing pasta on postprandial glycemia, appetite and energy intake in healthy individuals.

Eur J Clin Nutr

December 2024

Department of Community Health Sciences, College of Applied Medical Sciences, King Saud University, P.O. Box 10219, Riyadh, 11433, Saudi Arabia.

Background/objectives: In vitro studies suggest that incorporating sorghum flour into staple foods including pasta reduces their starch digestibility and hence may suppress postprandial blood glucose levels, appetite and energy intake; however, these effects in humans have yet to be reported. Therefore, this study investigated the effect of red and white sorghum-containing pasta on blood glucose response, appetite and energy intake in humans.

Subjects/methods: In a randomised crossover design, healthy individuals (n = 20) consumed the following three iso-caloric test meals (each providing 50 g available carbohydrates) as breakfast: control pasta (CP) made from100% durum wheat; 30% red sorghum pasta (RSP) and; 30% white sorghum pasta (WSP).

The Effects of Fat Content on the Shelf-Life of Vacuum-Packed Red Meat.

Foods

November 2024

Centre for Food Safety and Innovation, Tasmanian Institute of Agriculture, University of Tasmania, Private Bag 54, Hobart, TAS 7001, Australia.

When stored at chill temperatures, vacuum-packed (VP) lamb has a much shorter shelf-life than VP beef, primarily due to its higher pH, which could be linked to the higher fat content. The higher pH would create more favourable conditions for the growth of spoilage bacteria, resulting in a shorter shelf-life of meat. To determine the effects of fat on meat shelf-life as it relates to pH, a series of shelf-life trials at 2 °C were conducted using VP beef and lamb mince with varying fat contents (i.

  • Future climate changes will lead to more extreme weather, negatively affecting crop yields and quality, particularly due to heat stress, which is less understood for grain quality.
  • A study on safflower plants with different heat tolerances revealed that extreme heat reduced seed yield by 53-57% and altered fatty acid composition, with increases in saturated fatty acids and varying effects on unsaturated fatty acids over two years.
  • Heat stress impacted the physicochemical properties of safflower oil more significantly than the fatty acid profile, showing that certain parameters fluctuated based on environmental conditions and genetic tolerance.

Institute of Food Crops, Jiangsu Academy of Agricultural Sciences, Nanjing, Jiangsu, 210014, China.

Grain hardness has important effects on grain quality and the end-use of wheat. In this study, a collection of 103 common wheat germplasms and a DH population of 194 lines were used to identify new quantitative trait loci (QTL) for grain hardness. Two stable genetic loci on chromosome 5D were detected under different locations and years with one of them being the Ha locus on 5DS where the major gene Puroindolines for wheat grain hardness is located.

Co-Innovation Centre for Sustainable Forestry in Southern China, Bamboo Research Institute, Nanjing Forestry University, Nanjing, 210037, China.

Photosynthetic light response curves serve as powerful mathematical tools for quantitatively describing the rate of photosynthesis of plants in response to changes in irradiance. However, in practical applications, the daunting task of selecting an appropriate nonlinear model to accurately fit these curves persists as a significant challenge. Thus, there arises a need for a method to systematically evaluate the efficacy of such models.

Understanding the effects of barley yellow dwarf virus (BYDV) on crop agronomic traits and yield performance helps breeders balance their selection criteria and farmers decide if pesticides should be applied to control aphids that distribute the virus. To precisely assess the deterioration of different agronomic traits and yield components caused by different levels of BYDV infection, seeds of a BYDV-sensitive barley cultivar RGT Planet were space sown in a field plot with 10 cm between seeds and 20 cm between rows under two consecutive years. When BYDV symptoms were shown, plants with different levels (0 to 5) of BYDV infection were tagged.
