Abstract

Variations in plant growth, partitioning of dry matter and leaf area in seedling plants of F1 hybrid and open-pollinated Asparagus officinalis L. were measured and related to the yielding ability of the mature plants. The distribution of dry matter differed between hybrid (UC157) and the open-pollinated (OP) (UC72) cultivar. The root biomass was greater in the F1 throughout the experiment. From 2 to 14 weeks after emergence percent dry weight of root per plant ranged from 32 to 54 for the F1 and from 24 to 48% for the OP and percent dry weight of fern per plant ranged from 65 to 42% for the F1 and from 72 to 48% for the OP. Very high positive correlations were found between number of roots and stalks, length of stalk and root length, and “leaf” area and cladophyll dry weight.

Abstract

Asparagus, a cross-pollinated dioecious crop, is generally propagated through seeds, and extreme variation in yielding ability of individuals in a variety is common. Consequently, the use of small plot technique for field investigations has been virtually inapplicable.
