“…The whole plant DM increased from the earliest to the latest sampling date in 'Camarosa' D1 in 2002 and in D1 and D2 plants in 2004. The observed DM increase was consistent with previous works conducted with short day cultivars in Missouri and Japan, where plant DM increased from 3.05 g/plant, in August, to 10.83 g/plant, in October (Long and Murneek, 1937;Nishizawa et al, 1998). Except for 1998, where differences were not statistically significant, crown and root DM of D1 and D2 plants increased between extreme sampling dates (Table 2).…”

“…For example, Long and Murneek (1937) observed that the root DM of a short-day cultivar grown in Missouri increased from 0.70 g/plant in August to 3.30 g/plant in November. In Japan, Nishizawa et al (1998) also recorded similar values in the short-day cultivar 'Donner': 1.5 g/plant in September and 4.4 g/plant in October. Root growth during September -October might be attributed to the normal development of the roots as well as an increased allocation of reserve nutrients to this organ (Long and Murneek, 1937).…”

The pattern of total nonstructural carbohydrate (TNC) accumulation in strawberry (Fragaria ananassa Duch.) nursery runner plants, cv. 'Camarosa', was determined for three growing seasons. Plant growth and fruit production patterns were also evaluated. The experiments were carried out on plants propagated in high latitude (41°50' N) and high elevation (1292 m) nurseries in Siskiyou County, California. Plants were sampled beginning in late summer through early autumn and analyzed for dry mass (DM) and TNC. Plants from different digging dates were established in growth chambers (GC) at UC Davis or fruit evaluation plots in Irvine, California. In the nursery, TNC concentration in storage tissues increased steadily from the second week of September to the third week of October, and crown and root TNC concentration was positively correlated with the accumulation of chilling units (hours ≤7.2°C). The root TNC concentration consistently increased from 6 to 10% DM from mid-September to the first week of October. Transplant growth and fruiting pattern were affected by digging date. Overall, the roots were more sensitive to chilling in terms of TNC accumulation, than the crowns. Therefore, roots would be the appropriate organ for assessing TNC status and potential digging dates of strawberry nursery runner plants early in the fall.

“…The root and crown systems were the only plant parts that displayed any appreciable growth prior to spring and these levels diminished just as the plants started to produce flowers and fruit. Previous research has shown that when strawberry plants were labeled with 14 CO 2 in the fall, the plants utilized root carbohydrate reserves for early growth of flowers and leaves (Nishizawa et al 1998). Furthermore, Biela et al (1999) have shown that optimal vegetative and reproductive growth occurred when root zone temperatures were between 17 and 29 °C.…”

The growth and development of three strawberry cultivars commonly grown in a plasticulture system were documented. Strawberry plants were harvested monthly and divided by roots, crown, leaves, flowers, and fruit and then dried in an oven. The dry matter production and resource allocation proceeded along a predictable pattern of development. The establishment phase was characterized by an active period of growth of root, crown and leaves in the fall. Through the winter, the plants underwent slow growth, ending in a transition period in the late winter/early spring when resources were allocated to both vegetative and reproductive growth. In the spring, all plant parts received significantly increased allocation of, or redistribution of, resources. Cultivars of California origin, `Chandler' and `Camarosa', displayed similar trends in yield, dry matter production, seasonal resource allocation, and growth analysis variables throughout the season. `Sweet Charlie', a cultivar from Florida, showed lower dry matter accumulation and relative growth rate in the spring, higher harvest index and lower yield than the California cultivars.

“…Early spring growth of new leaves in the perennial strawberry plant is associated with a rapid decline and near depletion of carbohydrate reserves that had accumulated in vegetative organs the previous fall (Long and Murneek, 1937;Nishizawa et al, 1998). In our study under traditional mulching practices, carbohydrate reserves declined significantly even before new leaf growth began (Table 1).…”

Enhancing Early Spring Microclimate to Increase Carbon Resources and Productivity in June-bearing Strawberry

Effects of early spring cultural practices and microclimate manipulation on `Jewel' strawberry (Fragaria ×ananassa Duch.) plant development, carbohydrate reserves, and productivity were measured in the field and under simulated early spring conditions in growth chambers. With traditional winter straw mulching practices of the northeastern and midwestern United States, starch content of overwintering leaves, crowns, and roots in the field declined by 51%, 78% and 69%, respectively, during late winter and early spring. There was also a net loss in root biomass over winter and no new leaf growth before mid-April, suggesting that carbohydrate reserves could be limiting plant performance during the critical early growth and flowering phase in spring. In growth chambers, exposure to CO2 levels between 700 to 1000 mL·L-1 significantly increased photosynthetic rates of overwintering and spring leaves compared to ambient CO2 levels. Elevated CO2 in growth chambers also accelerated flower development, reduced depletion of starch reserves in roots, and increased starch accumulation in crowns. In the field, early removal of straw and application of spunbonded rowcover accelerated plant development, increased starch accumulation in the leaves, and increased photosynthetic rates of overwintering and spring leaves. Elevating the CO2 levels under rowcover further increased photosynthetic rates and advanced plant development and starch accumulation, but not significantly above rowcover alone. Carbohydrate losses later in the season during flower development were reduced when rowcover was applied in early spring. Total fruit yield was as much as 48% higher for plants under rowcover in early spring than those that had no cover and an additional 9% higher when CO2 was elevated. Yield improvements were attributed mostly to an increase in the number of marketable secondary and tertiary fruit than to an increase in mean fruit size. The economics of rowcover use is favorable if the material is reused. The added expense of CO2 gas and the resulting marginal gains would not make field CO2 enrichment an economically viable practice for strawberry growers using the method herein.
