Is leaf dry matter content a better predictor of soil fertility than specific leaf area?
BACKGROUND AND AIMS Specific leaf area (SLA), a key element of the 'worldwide leaf economics spectrum', is the preferred 'soft' plant trait for assessing soil fertility. SLA is a function of leaf dry matter content (LDMC) and leaf thickness (LT). The first, LDMC, defines leaf construction costs and can be used instead of SLA. However, LT identifies shade at its lowest extreme and succulence at ...
متن کاملChimerism status is a useful predictor of relapse after allogeneic stem cell transplantation for acute leukemia.
BACKGROUND AND OBJECTIVES The role of hematopoietic chimerism after allogeneic stem cell transplantation (SCT) for acute leukemia remains controversial. We studied the relationship between hematopoietic chimerism and several prognostic variables on the outcome of SCT in patients with acute leukemia. DESIGN AND METHODS Chimerism was determined by a semiquantitative method, based on polymerase ...
متن کاملIs The Value Spread A Useful Predictor of Returns?
Recent studies have used the value spread as a predictor of aggregate stock returns to construct cash-flow betas that appear to explain the size and value anomalies. Our evidence suggests that the value spread is not a useful predictor of returns. Two related variables, the book-to-market spread — the book-to-market of value stocks minus that of growth stocks — and the market-to-book spread — t...
متن کاملSoil Fertility and Salinity Status of Muzaffargarh District, Punjab Pakistan
The main objective of this paper is to check the soil fertility and salinity status. For this purpose, a total of 3325 soil samples, collected from all tehsils of Muzffargarh district (from tehsil Muzaffargarh, Jatoi, Kot Addu and Ali Pur), were tested in the Soil and Water Testing Laboratory, Cane Development Cell, Fatima Sugar Mills, Muzaffargarh, Pakistan from 2012 to 2014. Samples were anal...
متن کاملRelatedness is a poor predictor of negative plant–soil feedbacks
Understanding the mechanisms underlying negative plant-soil feedbacks remains a critical challenge in plant ecology. If closely related species are more similar, then phylogeny could be used as a predictor for plant species interactions, simplifying our understanding of how plant-soil feedbacks structure plant communities, underlie invasive species dynamics, or reduce agricultural productivity....
