Abstract
Fruit of loquat (Eriobotrya japonica Lindl.) grew slowly after set in autumn and quickly toward ripening in spring. A positive correlation was found between seed weight and fruit or pulp wieght, but there was only a weak or no positive correlation between number of seeds and fruit weight. The pattern of fruit growth was similar in ‘Tanaka’ and ‘Akko 1’. Thinning increased fruit size.
Abstract
Cultivars of fruit trees are vegetatively propagated in order to ensure a uniform crop with fruit of consistent quality. Unequivocal identification of the propagation material is essential for assuring the desired quality.
Abstract
The seed influences rate of growth, size, shape and maturation of avocado fruits. Seeded fruits are 8-10 times larger than seedless ones and contain more and larger cells. The growth pattern of seeded and seedless fruits is similar from June until maturation, when growth rate of seeded fruits decreases. Fruit maturation is characterized by rapid accumulation of oil in the mesocarp, preceded by shriveling of the seed coats, and the discontinuation of the seeds’ influence on fruit growth. The role of the seed in the development of avocado fruit is discussed.
