Plant regeneration via organogenesis from leaf and stipule explants of micropropagated shoots of strawberry (Fragaria $\times$ ananassa cv. Suhong) was achieved. Leaf and stipule explants were detached from shoot-tip cultured shoots and cultured on MS medium with various combinations of BA and NAA under light or dark condition. Shoot regeneration from leaf explant was observed after 3 weeks in culture and was good at the high ratio of BA and NAA among various combination treatments. The highest shoot regeneration frequency from leaf explants was obtained with 1.0 mg/L BA and 0.1 mg/L NAA, in which 31.1% shoot regeneration frequency(1.7 shoots per leaf explant) was yielded. In case of stipule explants, shoot regeneration was largely affected by plant growth regulators during incubation under dark condition for initial 4 weeks but not under continuous light condition. The combination treatment with 2.0 mg/L BA and 0.1 mg/L NAA showed the most excellent shoot regeneration from stipule explants, where 44.4% regeneration frequency(4.0 shoots per explants) obtained. Regenerated shoots were rooted on MS medium with 0.1 mg/L NAA after shoot elongation, and the plantlets regenerated were transferred to soil mixtures with vermiculite and perlite for acclimation.

The effect of cultural media and growth regulators on multiple plant regeneration from leaf explants of Heloniopsis orientalis (Thunb.) Tanaka was evaluated. The highest percentage of shoot and root formation were 20 and 30% on MS medium treated at 3.0 mg $l^{-1}$ of zeatin, respectively. Also 67 and 33% of high shoot formation appeared on 1/2 MS and 5 culture medium treated at zeatin 1.0 and 3.0 mg $l^{-1}$ respectively. With MS treated at 0.5 mg $l^{-1}$ of 2,4-D 1/2 MS and B5 culture media treated at each 1.0 and 3.0 mg $l^{-1}$ of zeatin the highest ratios of plant produced were 100, 280 and 310 % respectively relative to the other treatments. Generally, there was highest possibility for multiple propagation of Heloniopsis orientalis (Thunb.) C. Tanaka with B5 culture media supplemented 3.0 mg $l^{-1}$ of zeatin.

This study was carried the effect of transportation conditions and plant growth regulator on the maintenance of freshness and quality of cut Chrysanthemum 'Baekma'. The quality of cut chrysanthemum 'Baekma' which were stored at $5^{\circ}C$ was better than those of stored at $20^{\circ}C$ and control. When cut mum 'Baekma' was transported stacking boxes with vertical condition after dipping in distilled water, flowering degree, flower size, days to flower appearing degree, and bent neck were delayed. Flowering degree was delayed by $10mg/L^{-1}$ uniconazole spraying, The days to bent neck was delayed by 1,000x daminozide spraying.

This experiment was conducted to investigate the growth of plug seedlings and yield of tomato affected by the concentration of triazole and the treatment time. The length and leaf area of tomato seed-lings were reduced by the application of triazole compared to control. Growth reduction of seedlings was greater by earlier application and higher concentration of triazole. The growth of tomato treated with hexaconazole were similar with control 4 weeks after sowing. The triazole treatment lowered the height of the first fruit set compared to control. However, triazole treatment did not affect the number of fruits and yield.

This study was carried out to optimize the embryogenic callus induction and plant regeneration from mature seeds of Sorghum bicolor. The effect of growth regulators was investigated on formation of embryogenic callus. The highest frequency of embryogenic callus was observed when the mature seeds were cultured on B5 medium supplemented with 2 mg/L 2,4-Dichlorophenoxyacetic acid (2,4-D). The highest frequency of plant regeneration from embryogenic callus was observed on MS medium with 0.5 $mg\;l^{-1}$ 6-benzyl amino purine (BAP) and 0.25 $mg\;l^{-1}$ indole-3-butyric acid (IBA) to optimize the shoot regeneration. High concentration of BAP (1 $mg\;l^{-1}$) supplemented with IBA (0.25 $mg\;l^{-1}$) was effective combination for shoot multiplication. MS medium supplemented with 1 $mg\;l^{-1}$ IBA was found to be the most effective for inducing roots. Normal rooted plantlets were transferred to the greenhouse for hardening with over 90% survival rate. Hence, this reproducible protocol could be useful for mass propagation and genetic transformation of S. bicolor.

The experimental growth regulators Hoe78784 and PP-333 significantly reduced lodging in all rices. However, they did not significantly affect the crop vegetative characteristics and yield components, except by decreasing plant height when both growth regulators were applied at booting stage. Grain yield of IR21820-154-3-2-2-3 increased due to reduced lodging when Hoe78784 and PP-333 were applied at booting. These growth regulators increased the thickness and diameter of the culm. Applying CCC did not affect lodging in all test varieties. CCC-treated varieties and the control showed lower number of vascular bundles and culm thickness and diameter of the third and fourth internodes. Hoe78784 and PP-333 significantly reduced internode length from the second to the third internode in short-statured varieties. In tall varieties. reduction extended up to the fourth internode. Culm N content of the varieties did not significantly differ among treatments, except in IR8. Culm P content also did not differ significantly among treatments. although K and Si content was the highest than control when Hoe78784 was applied.

The infant seedling of rice(8-to 10-day-old) has often suffered from submergence just after transplanting due to the too short seedling height, 5 to 8cm, This experiment was conducted to elucidate the effect of gibberellic acid($GA_3 : 25% soluble liquid) with the application methods of foliar spray and seed-soaking on the elongation of seedling height of infant rice seedling in machine transplanting, We used a japonica rice variety, Hwaseongbyeo, and the seeding rate was 200g per seed tray(30$\times60$\times3cm). Generally,$GA_3 and Metalaxyl increased the elongation of seedling height of infant seedling while Tetracycle decreased the seedling height, To increase the seedling height of infant seedling, the foliar spary application of $GA_3 was better than seed-soaking treatment. The optimum concentration of $GA_3 for the foliar spray was about l0ppm and the optimum application time of $GA_3 was 3 to 4 days after sowing.
