flowering and fruit production of ‘nagami’ kumquat is somewhat different from other citrus species because usually have three flowering peak in a year which can lead to producing fruits with different quality on a tree. considering the proper effect of paclobutrazol on raising citrus flowering, a pot experiment with three levels of paclobutrazol (zero, 0.1 and 0.5 g ai per tree) and six replica...

In this study, conventional and organic olive tree nurseries were compared through a Life Cycle Assessment (LCA) analysis to identify processes that have greater environmental impact which of the two systems leads lower greenhouse gas (GHG) emissions. Carbon sequestration in woody biomass plants grown with both management was also considered. The research carried out on six nurseries, four mana...

feijoa as a fruit crop and ornamental tree is cultivated in the subtropics and warm temperate areas of the world including brazil, united states, new zealand and japan. a new disease with brown rot symptom on fruit occurred in feijoa orchards of northern iran in which it has become popular as a fruit crop. the objective of the present study was isolation and identification of the causal pathoge...

BACKGROUND Various studies have shown that the population densities of a number of forest vertebrates, such as orangutans, are higher on Sumatra than Borneo, and that several species exhibit smaller body sizes on Borneo than Sumatra and mainland Southeast Asia. It has been suggested that differences in forest fruit productivity between the islands can explain these patterns. Here we present a l...

This reproduces the calculations studied in Cochrane, Longstaff and Santa-Clara (‘Two Trees’, The Review of Financial Studies, vol. 21 no. 1, 2008) and Ian Martin, ‘The Lucas Orchard,’Econometrica, January 2013 (see especially Figure 3). It is an exercise that uses projection as a solution method. Consider an economy with two trees, tree number 1 and tree number 2. The quantity of fruit that fa...

(1) Background: Since early yield prediction is relevant for resource requirements of harvesting and marketing in the whole fruit industry, this paper presents a new approach of using image analysis and tree canopy features to predict early yield with artificial neural networks (ANN); (2) Methods: Two back propagation neural network (BPNN) models were developed for the early period after natura...

In other to study the effects of salicylic acid on reproductive characters of ‘Elberta’ Peach (Prunus persica L. Batsch) tree, an experiment was carried out based on randomized complete blocks design with four replications in commercial orchard, Kerman, Iran. The application of three concentrations of salicylic acid 0 (control), 1and 2 mM at swollen bud stage were used. Results showed that appl...

Fresh pistachio fruit cv. Kalleghochi was harvested from the exterior and interior parts of the tree canopy in four geographical directions. The fruit position in exterior and interior parts of the tree canopy has a significant influence on the number of nuts per ounce, pistachio splitting, hull weight, shell weight, kernel weight, colour indices and total anthocyanin content. Results indicated...

Studies of physiological diversity and its effect on the expression of traits in plants are used in breeding programs as a selective tool with the aim of selecting special attributes for creating a new product. In this study, the correlation coefficients among 17 horticultural traits of 34 genotypes from 11 different places of Semnan province were examined. A significant positive correlation wa...

Rhagoletis juglandis Cresson is a specialist that deposits its eggs into the husks of developing walnut fruit. Like other walnut infesting ßies in the R. suavis group, R. juglandis actively superparasitizes its larval hosts. However, little is known regarding the degree to which hosts are reused and the ecological context under which host reuse occurs. This Þeld study examined the pattern of ho...
