Planting density, above-ground dry-matter partitioning and fruit quality in greenhouse-grown `Flordaprince' peach (Prunus persica L..Batsch) trees trained to ``free-standing Tatura''

Vegetative growth, fruit yields, and dry matter partitioning within above-ground components were assessed during three growing seasons for trees of an early ripening peach (Prunus persica L. Batsch `Flordaprince' on GF 677 rootstock) trained either to a free standing central leader (930 trees/ha) or to Y shape (1850 trees/ha). Individual trees trained to central leader gave higher fruit yield, had a significantly greater leaf area and accumulated more dry mass in above-ground components per tree than Y shape trees. The training systems did not differ in terms of yield efficiency (yield per trunk cross-sectional area) and leaf area index (LAI), but Y shape trees had a higher harvest index and fruit dry mass per ground area than central leader. Four years after planting, Y shape had 35% higher yield per hectare than central leader. The relative contribution of 1-year-old wood, shoot and leaf to the dry mass of the tree decreased with tree age. Four years after planting the dry matter partitioned to the >1-year-old wood components represented 60% of the total tree mass (excluding fruit) in both the training systems. Central leader trees had the highest relative vegetative growth rate during stage III of fruit development. Most starch depletion occurred from dormancy to pit hardening from the canopy main storage pools (>1-year-old wood), and was higher for central leader than Y shape trees. For the ease of management and the high crop efficiency, the Y shape can be successfully used for peach high density planting systems.

Fig Tree

The objective of this work was to verify the influence of planting density on productivity and fruit quality of the fig tree. The design was used in three blocks, the plants of the cultivar Roxo de Valinhos were submitted to three planting spacings: 5 x 0.5 m; 5 x 1.0 m; and 5 x 1.5 m. The evaluated characteristics were: length of branches; average weekly growth of branches; fruit size; average fruit weight;soluble solids (°Brix); yield of mature fruits; productivity of green fruits; accumulated productivity; and dry mass of fruits.The length of the branches was not influenced by planting spacing, the plants conducted at lower densities presented higher productivity, both of green fruits and accumulated productivity.Plants submitted to lower planting density produced fruits with higher dry matter, but these were smaller in size, but without significant difference for those submitted to lower density. It wasconcluded that productivity is directly affected by fig planting density, but not all the qualitative aspects of the fruits were affected.

Size Controlled

Our objective was to evaluate the dry-matter partitioning between the roots and shoots of two genetically size-controlled peach [Prunus persica (L.) Batsch] types, dwarf and pillar, compared to a full-sized standard peach type. Compared to the pillar and standard types, the dwarf type had a reduced leaf: root ratio, less allocation of dry matter to woody tissue and more to leaf tissue. Genetically size-controlled peach trees have a smaller root system, but a lower leaf: root ratio and may require modified soil and water management techniques to ensure high productivity.

In reciprocal grafts of tall (`Elberta' and `Loring') and dwarf (`Empress' and `Juseito') peach (Prunus persica Batsch.) phenotypes, we measured dry-matter partitioning, resistance to root system water flow, and phytohormone content of xylem exudate. Scion characteristics determined the phenotype and growth characteristics of the tree irrespective of the rootstock. Tall phenotypes had higher dry weight and lower root resistance to water flow than dwarf phenotypes. Cytokinin-like activity and auxin levels in xylem sap were higher in dwarf than in tall phenotypes; whereas gibberellin-like activity was unaffected by either rootstock or scion. The scion of peach influenced phytohormone levels and resistance to water flow in the root system in addition to root and shoot growth.

Early Ripening

Effect of crop load on dry matter partitioning was studied on 3-year-old peach [(Prunus persica (L.) Batsch (Peach Group)] trees of the early ripening `Early May Crest' (EMC) grafted on `GF677' and Penta (Prunus domestica L.) rootstock and the late ripening `Flaminia' grafted on `GF677' rootstock [(Prunus persica × Prunus dulcis (Mill.) D. A. Webb] and grown outdoors in 230-L containers, for 2 years. Fruit thinning was carried out 10 days after fruit set to produce different crop loads. Trees were sampled destructively throughout two growing seasons and divided into above-ground and root components, for dry matter and carbohydrate analysis. At the end of the fruit development period, in the first year, total tree dry matter accumulation was related linearly to crop load even when the increase in crop load greatly decreased vegetative and root growth. Total dry matter accumulation was highest in EMC/`GF 677' at any specific crop load, and EMC trees on `GF677' allocated relatively more dry matter than EMC/`Penta' trees to vegetative and root growth, even under increasing fruit sink demand. Two consecutive years of heavy crops resulted in an inverse relationship between crop load and dry matter accumulation of trees, due to a major reduction of vegetative, root, and fruit growth. The percentage of dry matter partitioned to fruit decreased with the vigor of the rootstock, and EMC/`Penta' trees had the lowest harvest index at each specific crop load. The early ripening EMC/`GF677' trees which had twice the harvest index of `Flaminia'/`GF677' trees for any level of crop load. `Flaminia'/`GF677' trees had the largest canopy size. Starch content in the roots was lowest for cropping trees and depended on the rootstock and on the length of the fruit development period, being highest for the late ripening `Flaminia'/`GF677' trees. Individual fruit weight decreased with crop load, and the reduction of fruit size was related to rootstock and time of ripening.
