Predicting climate change impact on ecosystem structure and services is one of the most important challenges in ecology. Until now, plant species response to climate change has been described at the level of fixed plant functional types, an approach limited by its inflexibility as there is much interspecific functional variation within plant functional types. Considering a plant species as a se...

the influence of leaf pubescence of three wheat cultivars (pishtaz, ghuds and falat) on preference and biological parameters of sipha maydis (passerini) was investigated under greenhouse conditions (25 ± 2 °c, 70 ± 10% rh and 14: 10 h (l: d) photoperiod). the results showed that pishtaz had a greater density of trichomes compared to the other cultivars. in the preference test with whole plant, ...

In the present investigation attempts were made to estimate genetic parameters for yield and its components in 315 genotypes of cocoyam collected from thirteen aroid growing districts. Plant height, petiole length, petiole breadth, leaf number, leaf length, leaf breadth, LAI, Inflorescence length, peduncle length, spathe length, spathe breadth, corm length, corm breadth, cormel number, cormel l...

Correlation coefficient analysis conducted on 22 triticale x bread wheat derivatives along with six checks to select true- breeding derivative(s) for future hybridization programme with tolerance to drought and cold stress conditions as well as better quality traits revealed significant correlation of grain yield with spikelets per spike, biological yield, harvest index, leaf area index. Intere...

background: biostimulants are amino acids and organic components, which can play main role in the plant growth and dry matter accumulation. objective: determine the influence of foliar application of active amino acids on quality and quantity yield of melissa officinalis l. methods: this study was conducted in a research farm at the institute of medicinal plants on the base of randomized comple...

Aloe barbadensis Miller, commonly known as Aloe Vera is extensively used as a base element in preparation of medicine, cosmetics and food supplements. The objective of this study was to find out the effect of different levels of nitrogen on morphological and physiological characteristic of Aloe vera plants. Treatments included four levels of nitrogen (0, 500, 1000 and 1500 mg pot). After 12 mon...
