Nectar secretion in excised flowers. III. The dual effect of indolyl-3-acetic acid National Institute of Agronomic Research
Shuel, R. W..
The quantity of nectar sugar secreted by excised Antirrhinum flowers was reduced when indolyl-3-acetic acid (IAA) was added to the culture solution at 5 X 104M concentration. The volume of fluid was reduced by IAA in culture solutions containing 5-20% sucrose, but increased by IAA in pure water or dilute sucrose solutions. Pre-treatment with IAA produced the same effects as constant exposure. Calcium and potassium ions modified the action of IAA on water excretion. Nectaries of IAA-treated flowers differed in microscopic appearance from those of controls, and resembled the nectaries of flowers cultured in pure water. A dual effect of IAA on sugar and water excretion is inferred and, as a corollary, a partial independence of movement of the solid and liquid...

Nectarless, a yield-reducing mutant character in the muskmelon National Institute of Agronomic Research
Bohn, Guy Weston; Mann, Louis K..
The nectarless character in muskmelons first attracted attention in certain breeding lines in which blooms tied for pollination failed to become moist with nectar. The dry nectary itself, which is found in both staminate and perfect flowers, is smaller than a normal nectary. It is flat-topped in staminate flowers. A large portion of the nectar-producing tissue consists of collapsed cells and, in contrast to that of normal nectaries, con tains little starch before anthesis and produces little or no nectar after anthesis. Honeybees avoid nectarless flowers, especially in extensive plantings and in locations where other food sources are abundant. As a result, in contrast to normal plants, fruit set on nectarless plants is reduced and delayed.
