Studii asupra germinaţiei seminţelor şi răsăririi plantelor de revent (Rheum Rhabarbarum L.)

Seed germination and plantlets spring at rhubarb species were studied in the standard conditions on a peat substrate. Results revealed that the germination rate was of 90%, and spring rate was of 82%. Germination period had 12 days, starting in the 7-th day of experiment, and the spring was done in 10 day

Efectul distanţelor de plantare asupra creşterii şi producţiei de revent

The aim of the present research was to study the influence of planting distances on the growth and yield on rhubarb, cultivars of Victoria, Glanskin’s perpetual and local population. Applying differential cultivation technology, rhubarb yield varies according to crop density. The highest production was obtained in case of Victoria cultivar at density of 13.330 pl.ha-1 (0.75 m x 1 m). Statistically assured yields were also obtained at the density 10.000 pl.ha-1 (1 m x 1 m) on the same cultivar. Total yield varied within wide limits according to planting distances, ranging from 24.480 kg.ha-1 to 41.460 kg.ha-1

Efectul mulcirii şi a cultivarului asupra producţiei de revent

This paper presents the influence of mulch and cultivar on yield of rhubarb. The biological material used was represented by three cultivars: Glanskin's perpetual, Victoria and a local population. Were tested three mulching methods: mulching with straw, mulching with black polyethylene film of 15μ, mulching with black polyethylene film of 30μ and unmulched variant.Applying differential cultivation technology, rhubarb yield varies according to cultivar and mulch. The research was carried out in a rhubarb crop, in a four year production. The highest production was obtained in case of Victoria cultivar mulching with straw. Statistically assured yields were also obtained at Victoria cultivar un-mulched and Glankin’s perpetual cultivar mulching with straw
