We tested the resource availability hypothesis of antiherbivore defence with emergent wetland plant species. A physiological measure of the food quality of these species was derived using the growth rates of Ostrinia nubilalis larvae on agar-based di

The effectiveness of absorbed radiophosphorus for mutation induction in wheat and barley has been studied. The P32was supplied to seedlings and to young plants. Chromosome aberrations found in groups of several cells at meiosis were counted but singl

Microspore tetrads were rarely formed in three male-sterile potato varieties studied. Dyads and triads were much more common. The failure of the second meiotic divisions appeared to be the main reason for the lack of tetrads. Many of the microspores

Hybrids between vulgare (n = 21) and emmer (n = 14) wheats were backcrossed to vulgare, and segregates having the vulgare chromosome number were studied with respect to their emmer characters. Eleven of the 24 characters used in a vulgare-durum cross

When plants of a variegated barley are self-pollinated, they produce few variegated and many albino offspring. In different years the proportion of albino plants has ranged from 80.2 to 93.1% of the total population. Seed from heads having much green

The lethal dose of P32 and Sr90 for wheat, barley, and sunflower seeds is approximately 1.4 microcuries per seed (0.05 rd.). Radioautographs indicate that at five weeks' growth the distribution of phosphorus in a wheat plant is fairly uniform whereas

Between 600 and 900 ovules are estimated to begin development in single normal potato ovaries. The number of seeds per fruit ranged from 0 to 183 in 1941, from 7 to 472 in 1942.Sectioned ovules from several potato varieties were examined. Estimates o

A P32-treated vulgare wheat plant produced an offspring having yellow-green stripes on the leaves. The variegated leaf character is maternally inherited. Progenies of individual variegated selfed plants differ widely in the proportions of green: vari
