in a greenhouse experiment, the effects of waterlogging, sewage sludge and manure on the uptake and concentrations of p, k, ca, mg and na in root and shoot of sunflower (helianthus annuus l.) were investigated. a factorial experiment based on completely randomized design with three replications including duration of waterlogging at five levels (0, 2, 4, 8, 22 days), source of organic fertilizer...

Soil waterlogging is one of the major abiotic stresses adversely affecting maize growth and yield. To identify dynamic expression of genes or quantitative trait loci (QTL), QTL associated with plant height, root length, root dry weight, shoot dry weight and total dry weight were identified via conditional analysis in a mixed linear model and inclusive composite interval mapping method at three ...

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...

It is significant to monitor crop waterlogging range timely and correctly for later field management, agricultural insurance and yield prediction. The change regularity of paddy injured growth was analyzed and the sensitive parameters of growth stress were screened. The model of identifying the paddy waterlogging range based on change vector analysis (CVA) was developed by using the HJ-1/2 CCD ...

--Loblolly pine seedlings develop many responses under waterlogging stress that are similar to adaptations to waterlogging in other higher plants. Some of the responses of loblolly pine seem to be less specialized than those exhibited by true wetland species. Lack of specialization is some cases seems to account for growth differences in relation to soil nutrient level and length and type of wa...

Waterlogging is a common abiotic stress in both natural and agricultural systems, and it primarily affects plant growth by the slow oxygen diffusion in water. To sustain root function in the hypoxic environment, a key adaptation for waterlogging tolerant plants is the formation of adventitious roots (ARs). We found that cucumber waterlogging tolerant line Zaoer-N seedlings adapt to waterlogging...

Quercus robur L. and Quercus petraea (Matt.) Liebl. are sympatric oak species with different ecological requirements. Quercus robur is more tolerant to waterlogging than Q. petraea. This ecological divergence may play a role in the maintenance of the two species despite the absence of an insurmountable reproductive barrier between them. We predicted that the genetic architecture of traits relat...
