In the current study we have undertaken scientometric analysis to map research publications from 19 different animal science institutions under Indian Council of Agricultural Research (ICAR), for a period two decades (1998 2020), using Web Science (WoS) platform Clarivate Analytics. We analyzed parameters like year-wise citation records, institute-wise publication output, authorship pattern, ty...
Differences among tropical tree species in survival and growth to light play a key role in plant competition and community composition. Two canopy species with contrasting functional traits dominating early and late successional stages, respectively, in a tropical montane rain forest of Hainan Island, China, were selected in a pot experiment under 4 levels of light intensity (full, 50%, 30%, an...
Sub-optimal temperature extensively suppresses crop growth during cool-season greenhouse production. Root-zone (RZ) warming is considered an economical option to alleviate crop growth reduction. In this study we cultivated cucumber seedlings in nutrient solution under different air-RZ temperature treatments to investigate the effects of RZ warming on seedling growth- and photosynthesis-related ...
An efficient callus induction and plant regeneration system has been developed using salt and heat as pre-treatment factors for three barley genotypes viz. BB-3, BB-6 and BHL-18. Different concentrations of NaCl (1.5, 2.5, 3.5, 4.5, 5.5 and 6.5 g/L) were used and its effects were determined on the basis of the viability of callus (CV), plant regeneration (PR), relative growth rate (RGR) and tol...

 Purpose: To evaluate the implanted legislation and regulations in Jordan, order to minimize nanotechnology research-related health concerns.
 Methods: In first part, all published research Scopus database Jordanian National Database for Researchers were mined. The growth was analyzed by calculating relative rate (RGR), doubling time (DT), compound annual (CAGR). Thereafter, results ...
Chloride is an essential micronutrient for plants growth however it accumulates in large amounts in tobacco plants rapidly. To evaluate the effects of chloride concentrations in irrigating water on yield and growth indices of tobacco plant which has an important economic value, an outdoor pot experiment was established in completely randomized design during 2010 crop year at Guilan Tobacco Rese...
Arundo donax L. is a tall perennial reed classified as an emergent aquatic plant. In California, it has invaded riparian zones, where it acts as a transformer species. Because plant growth and leaf quality influence the effectiveness of management techniques, we sought to determine if these characters varied temporally and spatially in a northern California population of A. donax. Tissue C and ...
The question of why some introduced species become invasive and others do not is the central puzzle of invasion biology. Two of the principal explanations for this phenomenon concern functional traits: invasive species may have higher values of competitively advantageous traits than non-invasive species, or they may have greater phenotypic plasticity in traits that permits them to survive the c...
Understanding and modelling the dynamics of data point clouds of relative growth rate and plant size
Relative growth rates (RGR) have both intrigued and irritated many plant scientists since they were proposed as characteristics of performance in the early 20th century. Particularly, common trend RGR to decrease with increasing size, also referred ontogenetic drift, has given rise debates much criticism. In this study, we showed that, plants that germinated at same time, it is obtain a linear ...
Submergence stress can cause the death of grass plants. Identification of the association between molecular markers and submergence tolerance-related traits facilitates an efficient selection of the tolerant cultivars for commercial production. A global collection of 99 diverse perennial ryegrass (Lolium perenne L.) accessions was evaluated for submergence tolerance and analyzed with 109 simple...
