  1 - Preliminary Evaluation of Productivity and Fruit Quality for Seven Peach Rootstocks in Chile
  Sotomayor, C., J. Castro A. Bravo
  Fruit productivity and quality of eight years peach and nectarine cultivars (Rich Lady, Ryan Sun, Ruby Diamond and Venus) grafted onto Cadaman-Avimag, Viking, Atlas, GxN 15, GF 677, MRS 2/5 and Nemaguard (control) rootstocks were evaluated. A Split Plot experimental des چکیده کامل

  Fruit productivity and quality of eight years peach and nectarine cultivars (Rich Lady, Ryan Sun, Ruby Diamond and Venus) grafted onto Cadaman-Avimag, Viking, Atlas, GxN 15, GF 677, MRS 2/5 and Nemaguard (control) rootstocks were evaluated. A Split Plot experimental design was used, with each rootstock/scion combination as an experimental unit. Total yield, fruit size distribution, number of fruit, and fruit weight were recorded. Fruit quality parameters including soluble solids concentration (SSC), blush color development, and flesh firmness were also measured. On average, Cadaman yielded the greatest fruit weight and number of fruit, compared with the control, followed by GxN 15, Atlas and GF 677 to a lesser degree, while Viking was similar to the Nemaguard control, and MRS 2/5 yielded less than the control. There were no great differences between the rootstocks and the control with respect to fruit size and weight, although the most vigorous, Cadaman and GxN 15, were significantly higher (190.1 and 197.2 g, versus 179.5, respectively). For fruit quality parameters, Viking had the highest accumulation of SSC with respect to Nemaguard and MRS 2/5 had the highest percentage of blush color compared with the control. For flesh firmness at harvest, GF 677 was the firmest and MRS 2/5 was the softest. پرونده مقاله

  Several fruit trees including some cultivars of citrus tend to develop irregular bearing. Fruit thinning has been used for hundreds of years to manipulate blooming and crop load to improve the alternate bearing process. Frequently, combination sprays of two or more chemical thinners are used in various fruit trees and the thinning responses were additive and more effective than individual compounds. In this study, we investigated the effects of Naphthalene acetic acid and carbaryl alone and in combination in thinning of ‘Kinnow’ mandarin (Citrus reticulata Blanco) trees. Some characteristics such as fruit weight, diameter and volume, total soluble solid (TSS), titrable acidity (TA), TSS/TA, vitamin C and peel thickness were measured prior to harvest for 2010 and 2011 as a complete randomized block design with 13 treatments and four replications. Results showed that the application of NAA and carbaryl alone in June drop stage of fruit growth increased fruit thinning percentage, TSS of fruit juice, fruit weight, volume, diameter and length. These chemical thinners improved fruit size significantly by increasing the leaf/fruit ratio. Combination sprays could not effectively thin fruits than individual chemicals and thus had no effect on fruit size. Fruit characteristics such as TA, ascorbic acid, TSS/TA ratio and peel thickness were not affected by our treatments.      پرونده مقاله
