Tenure insecurity and thin land rental markets weakened the incentives to farmland investment in rural China, which was not conducive improving agricultural productivity. Thus, impacts of tenure security transfer on were analyzed by using household fixed effect model, IV method a 762 household-level 1163 plot-level data set. The results indicated that: (1) compared with owned plots, number farm...

The development of flower buds and a sufficient fruit set are basic requirements for fruit growers to generate a marketable crop. However, fruit trees remain in a juvenile (nonflowering) phase for years, and after a transition period of getting reproductively competent they enter the adult phase of tree life. The reproductive phase is associated with the ability to alternate between the product...

Sunburn of apple fruit is a surface injury caused by solar radiation that in the initial phase results in a light corky layer, golden or bronze discolouration, and other injuries to the epidermal tissue on the surface exposed to the sun. According to the definition of Retig and Kedar (1967), sunburn is a physiological injury that significantly affects fruit quality. Meteorological elements, the...

to be eff ective vectors of apple pollen.” Pollination is an essential step in production of fruits and many vegetables. Th e most widely used insect for fruit pollination is the European honey bee, Apis mellifera. Honey bees are ideal pollinators in many crop systems: each colony produces thousands of foraging workers and colonies can be moved into orchards and fields during the flowering peri...

The improvement of trap-lure combinations is an important part of integrated pest management programs that involve monitoring pests for timely insecticide applications, or for their use in control strategies such as mass trapping or bait stations. In this study improvements in the capture of Drosophila suzukii were not observed following the inclusion of different color stimuli with respect to ...

Many biotic and abiotic parameters affect the metabolites involved in the organoleptic and health value of fruits. It is therefore important to understand how the growers' decisions for cultivar and orchard management can affect the fruit composition. Practices, cultivars and/or year all might participate to determine fruit composition. To hierarchize these factors, fruit weight, dry matter, so...

It is now generally accepted, as pointed out by Westgate (1945), that the pineapple mealybug, Pseudococcus brevipes (Ckll.), is present in Florida, causing wilt as in other, pineapple growing areas. Control of the pine apple mealybug and/or of the ants infesting the soil and plants is, furthermore, usually considered to effect control of the wilt of pineapples, as shown by Illingworth (1931). B...

In ‘McIntosh’ apples (Malus domestica Borkh.), the number of well-formed seeds and the number of fertilized ovules (well-formed plus aborted seeds) were correlated to yield an index of asymmetry for individual fruit. In spite of different flowering and pollination conditions in 1990 and 1991, the index of asymmetry decreased curvilinearly with increases in the number of well-formed seeds and of...

The University of Vermont Apple Program received a USDA grant to study the long-term effects of “particle film technology” on Northeast apple orchards. This technology has been commercially available to growers since 2001 in the kaolin clay–based product Surround. Surround is viewed as a potential alternative for some organophosphate uses in orchards. It is considered a “Reduced Risk Pesticid...
