Fruit reflectance spectra of five apple (Malus domestica Borkh.) cultivars (Zhigulevskoe, Antonovka, Granny Smith, Golden Delicious and Renet Simirenko) with a wide range of peel pigment (chlorophylls a and b , carotenoids and anthocyanins) content have been studied to develop non-destructive techniques for pigment assessment. In addition to chlorophylls, positions of in vivo absorption maxima ...

Photosynthetic effects of the leaves extracts from Ipomoea cairica on Parthenium hysterophorus L were studied. Ipomoea cairica dried leaf powder (20g) was dissolved in distilled water (200ml) for foliar application. The seedlings were maintained under natural condition in Insect free net house. The experiment was carried out to analyze the effects of Ipomoea cairica leaves extract by measuring ...

An in vitro translation system using lysed etioplasts was developed to test if the accumulation of plastid-encoded chlorophyll a apoproteins is dependent on the de novo synthesis of chlorophyll a. The P700 apoproteins, CP47 and CP43, were not radiolabeled in pulsechase translation assays employing lysed etioplasts in the absence of added chlorophyll precursors. When chlorophyllide a plus phytyl...

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 order to study the effects of water deficit stress and foliar application of chitosan in safflower (carthamus tinctorius l.), a pot experiment was conducted in 2009. experimental design was a randomized complete block in factorial arrangement with three replications. experimental factors were water deficit levels (unstressed (control) and 70% available water depletion from soil (water defici...

to evaluate the effect of different levels of drought stress on some physiological parameters in strawberry, potted experiment involing strawberry cultivars  ‘marak٫ , ‘camarosa٫ and ‘gaviota٫ was conducted during summer 2009. the experiment consisted of three drought stress levels in three replications. the experimental arrangement was a factorial one, based upon a randomized complete block de...

to study the effects of biofertilizers on physiological and morphological characteristics, as well on essential oil content in dragonhead (dracocephalum moldavica), an experiment was conducted at tarbiat modares university in 2009. the studied factors were: vermicompost (0, 15, 30% v/pot), azotobacter (inoculated and non-inoculated), and phosphatic biofertilizer (inoculated and non-inoculated)....
