. Biennial report of the Oregon State Board of Horticulture ... Horticulture -- Oregon; Fruit-culture -- Oregon; Gardening -- Oregon. Ttl—Catherine; injured pistil. RAIN MAY INJURE FRUIT The unfruitfulness which often follows a rain timing the blooming sea- son is sometimes confused with self-sterility. A careful fruitgrower watches the weather anxiously when his trees are in blos- som, for he knows this is the most critical period in the growth of the crop. Injury to fruit blos- soms from rain is common wherever fruit is grown, but is ])articularly serious along the Pa- cific Coast and near the shores of the Great Lakes. It has been estimated that more fruit- is lost in California from cold rains during blooming time than from all other causes combined. Like winter-injury to fruit buds, there is no way of preventing this loss except to secure a more favorable location, since it is not in man's power to prevent rain, however much he may be able to induce it by bombarding the sky. Nevertheless, it is interesting to know in what way rain decreases the setting of fruit. If a rain comes while the trees are in full bloom the pollen is washed from those anthers which have already opened, and is thus prevented from reach- ing the stigma. Should the rain be a short one, no serious harm need result from this loss of pollen, for the unopened anthers will burst and pollination will begin again soon after the sun comes out. The washing away of pollen has very little influence in decreasing the setting of fruit, particularly when the rain is short. There will generally be enough pollen to supply the pistils before or after the rain. .—Catiieriiie; muninl Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Oregon.
