in order to evaluate the effect of zeolite application and selenium spraying on some physiological traits and grain yield in medicinal pumpkin (cucurbita pepo l.) under different moisture regimes, a study was conducted in a factorial experiment based on randomized complete block design with three replications during 2010 in takestan at gazvin province, iran. the three levels of irrigation facto...

in order to investigate the effects of corm tunic, corm weight and drought stress on saffron (crocus sativus l.), an experiment was conducted at the greenhouse of ferdowsi university of mashhad, iran. treatment were combination of four corm weights range (2-4, 4-6, 6-8 and 8-10 g), two levels of water availability (100% field capacity and drought) and two levels of corm tunic (natural corm with...

Abstract Determination of chlorophyll content as an indirect method of estimating the productivity of vegetation represents a good way to gain an understanding of the photosynthetic regime of plants. Physiological investigations of chlorophyll and carotenoid content in the uppermost internode of several wheat cultivars were carried out at the outset of the flowering phase. The dependence of chl...

To study the physiological and morphological relationships of two clover species affected by herbicides, Pursuit experiment in a factorial based on randomized completely design with 3 replications at the Damavand in 2012. The first factor consisted of two species of Trifolium pretense L. and Trifolium alexandrinum L. and the second factor consisted of three levels of herbicide...

The studies on growth regulation in black gram cv. ADT (Aduthurai) 5 exhibited significant changes in growth, physiology and yield due to chemicals and plant growth regulators. Foliar application of NAA @ 40ppm at pre-flowering stage influenced growth characteristics by showing increased plant height, more number of branches, higher leaf area index and leaf area duration. But, with regard to ph...

Alstroemeria is one of the most popular cut flowers in European Union owing to its postharvest longevity and broad color spectra. Nevertheless, premature wilting decreases the aesthetic value of flowering branches even before the opening of the secondary florets in the fluorescence. The present study evaluated different biochemical and morphological traits of Alstroemeria cut ...

Portable, non-destructive chlorophyll meters could be a valuable tool for forest managers and researchers. The ability of such meters to assess both chlorophyll and nitrogen content has been well established for many agricultural species, but not wellstudied for North American forest tree species. The objective of this study was to evaluate the ability of a portable chlorophyll meter to estimat...

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. ...
