late spring frost usually damages flowers and reduces yield of almond trees. due to natural sexual reproduction, in most of almond orchards of qazvin province, iran, which have been established through seedling propagation, a vast genetic variation has been occurred. this situation has been provided many possibilities to study different traits of native almond genotypes, to select superior geno...

some cerasus sub-genus wild species that are used as rootstocks in sour and sweet cherry propagation can also be employed in breeding programs. the aim of this study was to clearly evaluate some characteristics of subgenus cerasus genotypes to be used in the future cherries' breeding programs. in order to evaluate some morphological characteristics of the vegetative parts as well as seeds ...

Kazakhstan has very rich walnut genetic resources; however there is no ongoing walnut breeding program. Kazakhstan government has several projects in cooperation with Russia, USA, Bulgaria, Czech Republic and Poland for plant breeding purposes. In the present research walnut genetic resources originated from Jabağıl, Tulkıbas, Sayram, Lenger, and Botanical Garden of International Hodja Ahmet Ye...

A 3-year demonstration study was conducted in four western New York apple orchards to evaluate current approaches of sustainable pest management in representative commercial orchards. Pests that could be tolerated were regulated by natural antagonists, including predatory mites that were introduced to supplement endemic populations, while those with lower tolerance levels were managed with a sc...

Abstract. Autonomous orchard vehicles have been shown to increase worker efficiency in tasks including pruning, thinning, tree maintenance, and pheromone placing. To cover entire blocks, they must be able to repeatedly exit an orchard row, turn, and enter the next. The authors’ experience deploying autonomous vehicles for five years in commercial and research orchards shows that, when the map o...

Animal breeding traditionally has entailed devising means to apply quantitative and population genetic theory to increase productive capacity of livestock. A highly developed and successful industry has been built on foundations established by academic animal breeders. Recent developments in related sciences such as reproductive biology, molecular biology, cellular biology, and cytogenetics off...

ABSTRACT Pollination of the edible fig (Ficus carica cv. Calimyrna) is mediated by a small symbiotic wasp, Blastophaga psenes, that inhabits the syconium cavity of the spring crop of fig pollinator trees (caprifigs). These fig wasps also carry propagules, mainly of Fusarium verticillioides (formerly F. moniliforme) and other Fusarium spp., which cause endosepsis, from pollinator figs to the edi...

The main aim of our work was to investigate the breeding parameters in three orchard types Algeria (apple, cherry and nectarine) for better conservation existing species. A total 149 active Turtle dove nests were monitored these man–made agro-systems. Egg laying occurred from early May continued until mid-August. started later trees stopped earlier nectarines. Nest density higher apple orchards...
