Strawberry anthracnose, caused by Colletotrichum acutatum J.H. Simmonds, is one of the most important diseases of this crop in Huelva (southwestern Spain). Lesions can occur on all parts of the plant but anthracnose crown rot is specially severe leading to wilt and death of plants. In this work, the infection and colonization process of C. acutatum on strawberry plants was studied. ‘Camarosa’ s...

Furrow irrigation is the most common method of irrigating pistachio orchards in Iran. Water use efficiency using this close to 35%. Ten years ago, a subsurface drip (SDI) project was initiated with highly saline and alkaline water for first time Iran at Feyzabad research station, 34̊ 54ʹ 15ʺ N, 58̊ 45ʹ 37ʺ E, located northeast Iran, an altitude 850 meters from sea. The salinity sodium adsorption ...

This study developed and tested four methods for shrub height measurements with airborne LiDAR data in a semiarid shrub-steppe in southwestern Idaho, USA. Unique to this study was the focus of sagebrush height measurements on sloped terrain. The study also developed one of the first methods towards estimating crown area of sagebrush from LiDAR. Both sagebrush height and crown area were underest...

As a result of the work, commercial plantations’ design elements prostrate and semi-prostrate forms garden blackberry ( Eubatus Focke) were optimized. When constructing agrocenosis according to cordon-free bush technology, it is proposed place planting material in single-line with distance at least one meter between plants on wide rows covered black polymer film tube laid under for drip irrigat...

Regression models to predict diameter at breast height (DBH) as a function of tree height and maximum crown radius were developed for Caribbean forests based on data collected by the U.S. Forest Service in the Commonwealth of Puerto Rico and Territory of the U.S. Virgin Islands. The model predicting DBH from tree height fit reasonably well (R2 = 0.7110), with strongest in subtropical moist and ...

This paper characterizes the growth and crown morphology of young balsam ®r saplings naturally regenerated under a gradient of understory light environments and intraspeci®c competition densities for two size classes (50±100 cm and 100± 200 cm). Most growth and crown morphological parameters investigated were strongly related to the natural light gradient investigated (3±83% full sunlight), but...

Forest ecosystems are essential for the planet; however, they prone to anthropogenic disturbance. To counteract this trend,restoration practices such as reforestation used, in order recover degraded areas. The objective of study was evaluatethe development and survival a Chinameca, Atlamajalcingo del Monte, Guerrero. A plantation with species ofPinusayacahuite Pinuspatula carried out 784 m² plo...
