This study explores the relationship between endogenous ethylene levels in stress-induced fruit abscission in different cotton cultivars. The plants were exposed to soil waterlogging or high temperature (45C) stress during early reproductive phase. Ethylene synthesis was also modified using chemical ethylene regulators e.g. aminoethoxyvinylglycine (AVG) and 1-aminocyclopropane-1-carboxlic acid ...

• Community ecologists often assume a hierarchy of environmental sieves to predict the impact of multiple stresses on species distribution. We tested whether this assumption corresponds to physiological responses using impact of water level and shade in wetland vegetation as a model. • Seedlings of four wetland species were grown under full light and simulated canopy shade, both in drained and ...

Roughstalk bluegrass (Poa trivialis) is a weed in cool season grass seed production fields in Oregon. Populations of this weed are often greater in fields prone to waterlogging. A greenhouse study was conducted to investigate the morphological and physiological differences between recently established roughstalk bluegrass and tall fescue (Lolium arundinaceum) plants in response to simulated wat...

Waterlogging is a significant environmental constraint to crop production, and a better understanding of plant responses is critical for the improvement of crop tolerance to waterlogged soils. Aquaporins (AQPs) are a class of channel-forming proteins that play an important role in water transport in plants. This study aimed to examine the regulation of AQP genes under waterlogging stress and to...

abstract heterotrophic seedling growth has described as the product of the following dynamic and to transmit seed reserves and the conversion efficiency of mobilized seed reserves to seedling tissue. this research was carried out to evaluate germination and seedling growth of wheat seed (n8019) in the form of combined analysis design with crd arrangement. treatments consisted of 4 levels of wat...

Urban waterlogging seriously threatens the safety of urban residents and properties. Wargame simulation research on resident emergency evacuation from waterlogged areas can determine the effectiveness of emergency response plans for high risk events at low cost. Based on wargame theory and emergency evacuation plans, we used a wargame exercise method, incorporating qualitative and quantitative ...

the effect of tricyclazole application on waterlogging damage alleviation in canola seedlings was evaluated in a pot experiment in complete randomized design layout with three replications. treatments included: control (no waterlogging), waterlogging, tricyclazole plus waterlogging and tricyclazole. tricyclazole (75%) applied at three-leaf stage on canola seedlings. seedlings were exposed to wa...

in this research, catalase activity and leaf chlorophyll stability of satsuma mandarin on some citrus rootstocks under waterlogging condition were studied. experiment was conducted as factorial with randomized complete blocks and 6 replications. the first factor, include 7 soils from east mazandaran and the second factor included 7 different citrus rootstocks: 1. sour orange, 2. swingle citrome...

We determined the enzyme activities involved in the aerobic and anaerobic respiration of Kosteletzkya virginica on the 0, 10, 20, and 30 d of waterlogging to understand its respiratory characteristics. We also determined the enzyme activities on the 10 and 20 d of recovery after water drainage. Non-waterlogged seedlings were regarded as control during this experiment. All waterlogged seedlings ...
