For almost a century (42, 139) certain yeast, or yeastlike parasites of fruits and seeds have been known. They occur on a wide variety of crop plants and cause such diseases as stigmatomycosis," "yeast-spot," "eye spot," and "internal rot." They seemingly represent a phylogenetic unit. They have cylindrical or pyriform asci, and the hyaline ascospores often are characteristically arranged in two fascicles lying end to end. All have acicular ascospores. (See figs. 2, a-c; 5 , c; 11, hand i; 12, A; 13, c-h; 15,j-k.) They have similar habitats, and several species may simultaneously occur in the same fruit or …

The California beekeeping industry of more than 600,000 colonies produced in 1965 an income of nearly $8,500,000 (Stanger, 1966). In addition, honey bees are annually used to pollinate California crops worth $200 million. For the past 80 years this import

Path-Coefficient Analysis Of Correlation Between Honey Bee Activity And Seed Yield In (Allium Cepa L.), N. S. Shasha'a, William P. Nye, W. F. Campbell
All PIRU Publications
A path-coefficient analysis was used to furnish information on the inter-relationships of pollinating insect activity and components of seed yield in inbreds of Allium cepa L. The inbreds differed very significantly in their attentiveness to pollinating insects. Only one inbred exhibited a significant correlation (P <0.05 positive) between numbers of honey bees and seed yields. Separating the correlation coefficients into components of direct and indirect effects indicated that pollination attractiveness was not the limiting factor in seed set for inbreds in the experiment. Moreover, most of the variation in seed yield could be attributed to indirect effects on the components of yield, umbels per plant, flowers per umbel, percent per fertilized flower, and seeds per fertilized flower.
