Shortening of Breeding Periods of Hydrangea Hybrids through Ovule Culture and Regulation of Flowering
breaking of dormancy cool temperature treatment flower induction low temperature treatment
2010/11/24
For breeding Hydrangea, it is an advantage to breed new hybrid cultivars in as short a time as possible. To this end, we used ovule culture and regulation of flowering to shorten the breeding period o...
Investigation of Environmental Factors Inducing Unfilled Pea Pods (Pisum sativum L.) (1) Effects of Shading and Temperature on the Development of Pod and Ovule
abortive ovule low day-temperature low light intensity underdeveloped ovule
2010/11/24
Effects of day and night temperatures and shading on the development of ovules and pea pods (Pisum sativum L. ‘kishu-usui’) were investigated during the entire winter cropping season. Percentages of u...
Production of Interspecific Hybrid Plants by Crossing Hydrangea macrophylla f.hortensia (Lam.) Rehd.and H.quercifolia Bartr.through Ovule Culture
Production Interspecific Hybrid Crossing Hydrangea macrophylla
2009/7/13
Interspecific hybrids of Hydrangea macrophylla and H. quercifolia were obtained through ovule culture. H. macrophylla ‘Blue Diamond’, ‘Haruna’ and H. quercifolia ‘Snow Queen’ were used. No viable hybr...
Development of Ovule and Embryo Sac in Relation to Double Seed Formation in Peaches
Ovule and Embryo Double Seed Peaches
2009/7/10
The development of ovule and embryo sac was investigated in relation to double seed formation in peaches. Among 15 cultivars, ‘Juseito (red flower)’ showed the highest percentage of double seed format...
Distribution of Double-Ovule Fruits in Each Individual Sugar Beet
