Abstract
|
|
|
This experiment was carried out to determine the optimum level of planting density for reduction of secondary growth in virus-free seed cloves of garlic cv. Euiseong (Album sativum L.) obtained by apical meristem culture in vitro.
The virus-free seed cloves, were planted on November 3, 1992, and harvested on June 17, 1993 in the experiment farm of Kyeongbuk Provincial R.D.A.
Virus-free seed cloves grew well as compared with the infected in terms of the plant height, leaf number and neck diameter. Neck diameter and individual bulb weight were decreased with increased planting density but the yield per unit area was increased. Secondary growth in virus-free seed cloves was 11.3% higher than that of the nonvirusfree. The planting density of 15×15㎝ turned out 58.3% of secondary growth, whereas 10×10 ㎝ made 33.7%. The larger seed cloves planted, the larger bulbs in weight and diameter produced, but it increased secondary growth also. Seed cloves of 4∼5 g produced average weight of 52.7 g per bulb. On the basis of this experiment, high density of planting as 10×10 ㎝ was recommendable for seed clove production and 15×10 ㎝ planting for commercial production in virus-free garlic.
