Trees have a fractal-like branching architecture that determines their structural complexity. We used terrestrial laser scanning technology to study the role of foliage in complexity urban trees. Forty-five trees three deciduous species, Gleditsia triacanthos, Quercus macrocarpa, Metasequoia glyptostroboides, were sampled on Michigan State University campus. studied by calculating box-dimension...

In order to investigate the appropriate combination of chemical and bio-fertilizers and their effectiveness on corn seed yield while defoliating the upper leaves of the ear, a randomized complete block design experiment with four replications. Fertilizer treatments were applied at four levels including 100% urea, 75% urea + 100% Nitroxin, 50% urea + 100% Nitroxin, 25% urea + 100% Nitroxin. In h...

This study was initiated to observe the performance of yuzu (Citrusjunos Sieb. ex Tanaka) fruit trees when affected by a late freezing in 2018 and evaluate recovery frost-damaged during post management under protected cultivation. A—4.9 °C minimum daily temperature 40-day drought occurred dormancy, which then received heavy precipitation between early- mid-March, with 15 m s−1 more than maximum...

High doses of nitrogen (N) fertiliser input on permanent pastures are crucial in terms N surplus and losses. Quantitative analyses the response plant functional traits (PFT) driving crop growth rate (CGR) under low lacking frequently defoliated pastures. This study aimed to understand significance PFTs for productivity uptake grasslands by measuring dynamics tiller density (TD), weight (TW), le...

Abstract Larch caterpillars are widely distributed in the Great Xing’an boreal forests; however, relationship between caterpillar defoliation dynamics and climatic factors is poorly understood. The aims of this study to investigate primary weather conditions that might influence forest identify most important life stage larch at which be mitigated by incorporating more inhibitory influences fro...

AIMS The objective of the study was to characterize variations in proline, arginine, histidine, vegetative storage proteins, and cold-inducible gene expression in overwintering roots of field-grown alfalfa, in response to autumn defoliation, and in relation to spring regrowth and winter survival. METHODS Field trials, established in 1996 in eastern Canada, consisted of two alfalfa cultivars (...

Post-anthesis drought affects wheat production worldwide, primarily through the limitation of grain filling. The enhanced remobilization stem reserves induced by can provide considerable carbon sources for aim this study, which was part an ongoing wheat-breeding program targeting tolerance, to assess ability 20 contrasting common genotypes (2 cultivars, 8 F6:7 families (FAM), and 10 parent (PAR...

After decades of multiyear defoliation episodes in southern New England, Lymantria dispar (previously gypsy moth) populations diminished with the appearance L. fungus 1989. Multiyear defoliations did not occur again until 2015–2018. To assess impact return defoliations, we examined 3095 oaks on 29 permanent study areas Connecticut and Rhode Island that were established at least 11 years before ...

Understanding crop response to manipulations in source (number of leaves) and sink (panicle) during the growing season provides useful information develop breeding strategies. In present study, we assessed how source-sink manipulation can affect sorghum (Sorghum bicolor L.) yield its components—grain number grain weight (including filling dynamics)—for hybrids released past 60 years. The field ...

Brushtail possums (Trichosurus vulpecula) tend to eat young canopy foliage in southern rätä (Metrosideros umbellata), and browsing tends to be concentrated on only a few trees. Samples collected as part of an artificial defoliation experiment were analysed for NPK (nitrogen, phosphorus, and potassium), carbohydrate, and polyphenolic concentrations to determine whether changes in foliar chemistr...
