Rapiddevelopment of the seeds then takes place. It is a rather briefperiod from the time of this fertilization until the seeds are of fullsize. The garden pea develops seeds in a few days or a few weeksafter blossoming. In the bush fruits this growth is rapid. Wintervarieties of apples require nearly the whole season. While the plant is developing the seed crop, much attentionmust be given it. Good tillage and plenty of available plant foodare both desirable. It is a critical time in the life of the plant and. Fig. 8.—Cleistogamous or hidden blossoms at the base of a violet clump, (U. S. D. A.) many crops of fruit and seeds are reduced by improper conditionsduring this time. Store of Nourishment in Seeds.—The plant stores up a consid-erable amount of nourishment in its seed crop. This explains whythe maturing of seeds is so devitalizing to the plant. The food stored in seeds sustains the life of the young plantuntil it is able to obtain nourishment through its roots and is because of this store of nourishment that we use seeds of somany kinds for human food and for stock feed. SAVING GARDEN SEEDS Gardeners, both young and old, should save garden seeds moresystematically. In many cases much better results can be obtainedif we save seeds from our own gardens.
