in this study, the effect of four citrus rootstocks {sour orange (citrus aurantium), bakraeii (c. reticulata × c. aurantium, mexican lime (c. aurantifolia) and volkamerlemon (c. volkameriana)} on orlando tangelo leaf chlorophyll content and mineral element concentrations (n, p, k, ca, na, mg, fe, zn, mn, cl, cu, and b) have been evaluated in completely randomized design with four replications. ...

A field-portable tool for nondestructive foliar anthocyanin content estimation would be beneficial to researchers in many areas of plant science. An existing commercial chlorophyll content meter was modified to measure an index of anthocyanin content. The ability of the experimental anthocyanin meter (ACM) to estimate total extractable anthocyanin content was tested in sugar maple (Acer sacchar...

The net photosynthetic rate, chlorophyll content, chlorophyll fluorescence and 820 nm transmission were investigated to explore the behavior of the photosynthetic apparatus, including light absorption, energy transformation and the photoactivities of photosystem II (PSII) and photosystem I (PSI) during senescence in the stay-green inbred line of maize (Zea mays) Q319 and the quick-leaf-senescen...

abstract to investigate the effects of paclobutrazol (pbz) on vegetative and reproductive growth of strawberry cv. selva a factorial experiment in a completely randomized design with three replications was carried out in greenhouse of agriculture college, isfahan university of technology. pbz was applied in two methods, drench and foliar spray, at 0, 0.5, 1, 1.5 and 2 mg active ingredient per p...

The objective of this experiment was to study of water relations and chlorophyll in different wheat genotypes and their correlations with grain and biological yields. 21 genotypes of bread wheat were compared in a field experiment as randomized complete blocks design with four replications. The results showed that relative water deficit, relative water loss, excised leaf water retention, cell m...

One of the main factors affecting vegetation productivity is absorbed light, which is largely governed by chlorophyll. In this paper, we introduce the concept of chlorophyll efficiency, representing the amount of gross primary production per unit of canopy chlorophyll content (Chl) and incident PAR. We analyzed chlorophyll efficiency in two contrasting crops (soybean and maize). Given that they...

the measurement of chlorophyll content of leaf is as an appropriate criterion in breeding programs to increase the rate of leaf photosynthesis. in order to study the relationship between chlorophyll content and seed yield under saline conditions, 41 wheat genotypes were evaluated in two conditions (normal and salinity stress) at the research field of the national salinity research center (nsrc)...

the influence of water deprivation on potted grape (vitis vinifera l.) was investigated. leaf mass area (lma) and biochemical responses, including chlorophyll, total protein, peroxidase activity, soluble carbohydrates, photosynthesis and stomatal conductance were assessed in leaves of ‘sahani’ and ‘bidane sefid’ grape cultivars subjected to progressive drought (soil water potentials of: -0.2, -...

  Abstract Two experiments with factorial arrangements on the basis of randomized complete block design in three replications were conducted in 2007 and 2008, to evaluate chlorophyll content index (CCI), fluorescence of chlorophyll, proline content and grain yield of three soybean cultivars (Williams, Zan and L17) under a non-saline (control) and three saline (3, 6 and 9 ds/m NaCl) conditions...
