In this study, the response of selected almond cultivars on different rootstocks under drought stress base on Morpho-physiological traits using a factorial experiment in a randomized complete block design with three replications was investigated. The experimental was carried out at the Temperate Fruit Research Center of Horticultural Sciences Research Institute (HSRI) in 2016. The factors inclu...

This study was conducted to determine effect of water stress on chlorophyll content and chlorophyll fluorescence parameter in young `Dezful’ olive trees. Three irrigation regimes (40% ETcrop, 65% ETcrop and 100% ETcrop) were used. After irrigation treatments were applied, some of biochemical parameters including chlorophyll a, b, total chlorophyll, chlorophyll fluorescence and also chlorophyll ...

The chlorophyll fluorescence imaging technique is a valuable tool to study the impact of heavy metal stress in plants. The aim of this paper was to investigate the influence of Cd on photosynthetic apparatus of white cabbage (Brassica oleracea subsp. capitata f. alba) plants. Two cabbage cultivars ‘Ditmarska Najwcześniejsza’ (‘DN’; early) and ‘Amager Polana’ (‘AP’; late) were used. Cd was appli...

Soybean is an important legume food crop, and its seeds are rich in nutrients, providing humans animals with edible oil protein feed. However, soybean sensitive to water requirements, drought factor limiting yield quality. This study used Heinong 84 (drought resistant variety) Hefeng 46 (intermediate as tested varieties planted chernozem, albic, black soils. The effects of stress on the activit...

M odulated 685-nm chlorophyll fluorescence was measured under steady-state conditions in pea leaves adapted to m oderate actinic light. W hen the m easurem ents were perform ed after a short exposure to heat (42 °C) in darkness, the maximal (Fm) and steady-state (Fs) fluorescence levels were dram atically and irreversibly quenched whereas the basic fluorescence F0 rem ained unchanged. C oncom i...

Huanglongbing (HLB) is one of the most destructive diseases of citrus, which has posed a serious threat to the global citrus production. This research was aimed to explore the use of chlorophyll fluorescence imaging combined with feature selection to characterize and detect the HLB disease. Chlorophyll fluorescence images of citrus leaf samples were measured by an in-house chlorophyll fluoresce...

Leaf chlorophyll fluorescence parameters as well as chlorophyll content were compared in three dominant mangrove species grown in two zones with different salinity in the Bhitarakanika National Park. The accumulation of dry matter and chlorophyll content in leaves decreased under high saline conditions. Quantification and de-convolution of chlorophyll fluo-rescence transient into several phenom...
