Estimates of crop canopy chlorophyll content (CCC) can be used to monitor vegetation productivity, manage resources, and control disease pests. However, making these estimates using conventional ground-based methods is time-consuming resource-intensive when deployed over large areas. Although indices (VIs), derived from satellite sensor data, have been estimate CCC, they suffer problems related...

The leaf chlorophyll content (Chlleaf) is a key indicator of the physiological condition vegetation and integral for harvesting solar radiation required to drive photosynthesis (Evans, 1989; Vernon & Seely, 1966). Retrievals Chlleaf are crucial providing important information on plant stress diseases, modelling productivity serving as proxy photosynthetic capacity within terrestrial biosphere m...

effects of drought stress and chemical treatments was studied on growth and developmental traits of four barley cultivars using a split- split plot design (rcbd) in agricultural research farm, kerman university. main plots consisted of irrigation (control and drought stress after flowering), sub-plots consisted of four barley cultivars ( ʻnosratʼ, ʻafsalʼ, ʻyousofʼ and ʻuh12 lineʼ) and sub-sub ...

Fifty-three leaves were randomly sampled on different deciduous tree species, representing a wide range of chlorophyll contents, tree ages, and leaf structural features. Their reflectance was measured between 400 and 800 nm with a 1-nm step, and their chlorophyll content determined by extraction. A larger simulated database (11,583 spectra) was built using the PROSPECT model, in order to test, ...

Drought stress is one of the most important environmental stresses affecting plant growth, yield and crop production around the world. It is believed that arbuscular mycorrhizal fungi are used for protecting plants against drought damage.Vesicular-arbuscular mycorrhizal fungi have been used in recent years to cope with water stress in many plants. In this study, the relationship between water d...

In this study, the response of selected almond cultivars on different rootstocks under drought stress base on Morpho-physiological traits using a factorial experiment in a randomized complete block design with three replications was investigated. The experimental was carried out at the Temperate Fruit Research Center of Horticultural Sciences Research Institute (HSRI) in 2016. The factors inclu...
