Local haplotype patterns surrounding densely spaced DNA markers with significant trait associations can reveal information on selective sweeps and genome diversity associated with important crop traits. Relationships between haplotype and phenotype diversity, coupled with analysis of gene content in conserved haplotype blocks, can provide insight into coselection for nonrelated traits. We perfo...

This study was conducted to investigate variations of leaf chlorophyll content and surface spectral reflectance of different tree species (Daphniphyllum glaucescens、Michelia formosana、Illicium dunnianum and Machilus kusanoi) across contrasting terrain in the Nanjenshan Reserve of Kenting National Park, Southern Taiwan. The results showed that there were significant differences (P < 0.01) among ...

drought tolerance of three own-rooted grape cultivars (rashe, ghezil uzum and red sultanina) was evaluated at four different levels of soil moisture contents (40, 60, 80 and 100% field capacity through a factorial experiment based on a randomized complete block design with three replications for a duration of 3 months. results revealed that, grape cultivars, levels of soil moisture and the inte...

Quick non-destructive assessment of leaf chlorophyll content (LCC) is important for studying phenotypes related to plant growth and stress resistance. This study was undertaken to investigate the quantitative relationship between LCC and different vegetation indices (VIs) on both adaxial and abaxial surfaces of white poplar (Populus alba), which has dense tubular hairs on its abaxial surface, a...

Methods for chlorosis detection and physiological condition monitoring in Vitis vinifera L. through accurate chlorophyll a and b content (Cab) estimation at leaf and canopy levels are presented in this manuscript. A total of 24 vineyards were identified for field and airborne data collection with the Compact Airborne Spectrographic Imager (CASI), the Reflective Optics System Imaging Spectromete...

Leaf chlorophyll content is not only an important biochemical parameter for determinating the capacity of rice photosynthesis, but also a good indicator of crop stress, nutritional state. Due to the reliable, operational and non-destructive advantages, hyperspectral remote sensing plays a significant role for assessing and monitoring chlorophyll content. In the study, a few of typical vegetatio...

A growing number of studies have focused on evaluating vegetation indices in terms of their sensitivity to vegetation biophysical parameters as well as to external factors affecting canopy reflectance. In this context, leaf and canopy radiative transfer models have provided a basis for understanding the behaviour of such indices, particularly their resistance to external perturbing effects rela...
