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 ...

17-day-old bean plants (Phaseolus vulgaris cv. Strike) were used to analyze the effects of Co2+ and Zn2+ on the time course of proline, total protein, chlorophyll and abscisic acid (ABA) levels in leaves. Controls, Co2+ and Zn2+-treated plants were grown for 8 days in Hoagland solution. Samples were taken at 2 day intervals. Proline, chlorophyll (a+b) and total protein contents of 17 day old pr...

This study was conducted to determine the effect of compost and compost tea on growth and physiological parameters of Lepidium sativum L. 30-day-old Cress plants treated with compost and compost tea were harvested and different growth and physiological parameters were measured. Compost tea application increased RGR, SLA, ULR and RLAGR. The contents of Chlorophyll a and Chlorophyll b in the plan...

Oxidative stress effects on growth, viability, pigment (chlorophyll a, chlorophyll b, β-carotene) and protein contents in Antarctic microalga Choricystis minor were investigated. C. minor was cultivated at optimal (23.5oC), or extreme (15oC 27.5oC) temperatures and light intensity of 520 and 1000 μmol m-2 s-1. Oxidative stress was developed by adding Sanosil which degrades to H2O2 and Ag +. As ...

This study was conducted to determine the effects of different irrigation water treatments and silicon doses on leaf SPAD meter readings, chlorophyll content carotenoid contents tomato plants. Tybiff Aq seedling were grown in 3-liter pots filled with 1100 g 1:1 peat-perlite mixture for 70 days. Four type waters prepared use sea tap water. Irrigation included I) Full water, II) ½ + III) ¼ ¾ IV) ...

the microalgae, dunaliella salina was isolated from maharlu salt lake, south east of shiraz, iran. the isolated strain was identified by both morphological and physiological markers. the complete its region (its1 + its2) including the 5.8s rdna gene used as molecular marker confirmed our identification. growth and cell proliferation, total chlorophyll and carotenoid contents were determined in ...
