碩士 === 國立中興大學 === 園藝學系 === 85 === In order to understand the effect of calcium application on shoot, berrygrowth and nutrient content in Honey Red grapevines (Vitis vinefera L.×Vitislabrusca L.), five levels of dolomite of 0,40,80,120,160 and 200kg CaO/0.1hawere treated in the vineyard before bud forcing. For the first harvest period,the average length of shoot appeared 104∼128 cm, and the shoots node weidthwas 9.2∼9.8 mm, in the harvest stage, it was shown that there was notsignificant difference among treatments. For the second harvest, the time ofshoot stop to growth was 10 days earlier than that of the first harvest, theshoots growth also had not any difference among treatments.Leaf area,leafweight and leaf chlorophyll content were decreased when the calcium application was increased. The growth of fruit was shown in double sigmoid curve. The fresh weightand size of berry was more bigger associated with the lower firmness whencalcium did not applied, while total soluble solid, acidity and water contentof berry appeared more higher fllowed high levels of calcium application. The calcium and magnisium content of shoot, leaf and berry had not anysignificant difference in treatments. When calcium application was increased,the calcium and potassium content of shoot , leaf and berry was increased,alile the magnisium content in the same part was decresed.
