TL;DR: Genotype x environment interaction variances were generally small for all traits except yield and bolls per plant and lint yield was highly positively correlated with lint percentage and boll per plant.
Abstract: Plot error variances were large for lint yield, bolls per plant, seed per boll, and boll weight; small for lint percentage, seed and tint index, and fiber length, strength and fineness. Genotype x environment interaction variances were generally small for all traits except yield and bolls per plant. Lint yield was highly positively correlated with lint percentage and bolls per plant and negatively correlated with seed index and weight per boll.

TL;DR: In this paper, the ratio of absorption of fixed vs. applied nitrogen by two legumes was determined to determine the degree of reduction in nitrogen fixation in Ladino clover and alfalfa.
Abstract: SynopsisN¹⁵-labeled fertilizer was used to determine the ratio of absorption of fixed vs. applied nitrogen by two legumes. Seedlings of both Ladino clover and alfalfa as well as established Ladino clover plants absorbed applied N fertiliser. Nitrogen fixation was reduced by nitrogen application, with the degree of reduction being definitely related to the amount of nitrogen applied.

TL;DR: When reading the PDF, you can see how the author is very reliable in using the words to create sentences, and also the ways how theAuthor creates the diction to influence many people.
Abstract: When reading the PDF, you can see how the author is very reliable in using the words to create sentences. It will be also the ways how the author creates the diction to influence many people. But, it's not nonsense, it is something. Something that will lead you is thought to be better. Something that will make your feel so better. And something that will give you new things. This is it, the soil plant relationships.

TL;DR: Stipple has not yet been seen in the grape producing areas in the Coachella, Napa, Sacramento, and San Joaquin valleys of California, and can be incited in grape by fumigation with ozone.
Abstract: Small, brown to black, discrete, punctate lesions occur on the upper leaf surface of grape grown in areas polluted by air-borne oxidants. The lesions are typically restricted to the palisade layer and may be easily distinguished from other grape disorders because of their stippled appearance. The disease can be incited in grape by fumigation with ozone. Toxic ozone leaves occur in the polluted air mass above the Los Angeles and San Francisco areas where oxidant stipple is found. Stipple has not yet been seen in the grape producing areas in the Coachella, Napa, Sacramento, and San Joaquin valleys of California. 4 references, 3 figures.

TL;DR: Defoliation caused reduction in all measures of yield but increased weight per seed and stem yield and increased seed weight enough to maintain seed yield in severe depodding.
Abstract: SynopsisDefoliation caused reduction in all measures of yield. Severe, 8070, depodding reduced seed yield but increased weight per seed and stem yield. Moderate depodding, up to 40%, increased seed weight enough to maintain seed yield. Eighty percent depodding increased sugars, starch, and nitrogen in leaves and stems. Eighty percent defoliation increased the iodine number of seed oil, but decreased the oil and protein in seeds. Depodding increased seed protein but decreased the oil content and iodine number.
TL;DR: Irradiation of seeds of Adams and Hawkeye soybeans with X-rays and thermal neutrons significantly increased the genetic variability for yield, plant height, maturity, and seed size and predicted genetic gains from selection indicated that an advance could be made within each population for all characters except plant height.
Abstract: SynopsisIrradiation of seeds of Adams and Hawkeye soybeans with X-rays and thermal neutrons significantly increased the genetic variability for yield, plant height, maturity, and seed size. The estimates of genetic variance in the irradiation treatments averaged five times as large as those in the controls, and the predicted genetic gains from selection indicated that an advance could be made within each population for all characters except plant height.
TL;DR: Performance patterns of several corn hybrids were changed with respect to grain yield, barrenness, tillering and in one instance, root lodging when Texas (T) cy toplasm was substituted for the hybrids' normal cytoplasm.
Abstract: SynopsisPerformance patterns of several corn hybrids were changed with respect to grain yield, barrenness, tillering and in one instance, root lodging when Texas (T) cytoplasm was substituted for the hybrids' normal cytoplasm. Grain yield and barrenness of another hybrid were affected when USDA (S) cytoplasm was substituted for its normal cytoplasm. The extent and direction of these induced changes were markedly affected by (1) the genotype and (2) the physical environment during the growing season.
TL;DR: Rotary hoeing performed when weeds were germinating but not emerged, and repeated once or twice at approximately 5-day intervals, reduced weed infestations 70 to 80% and soybean stands about 10% in solid-seeded and row-planted soybeans.
Abstract: SynopsisRotary hoeing performed when weeds were germinating but not emerged, and repeated once or twice at approximately 5-day intervals, reduced weed infestations 70 to 80% and soybean stands about 10% in solid-seeded and row-planted soybeans. Bean yields were only slightly less than those from weed-free plantings. When hoeing was delayed until weeds had emerged, both weed control and bean yield were impaired 50%. Wet soil conditions before or after hoeing reduced its effectiveness.
TL;DR: One factor pair conditioned type of inflorescence as mentioned in this paper was dominant over sub-sessile inflorescence and the symbols Se and se have been assigned to this factor pair, which was inherited with dominance and complementary gene effects toward long peduncles, high flower number, and high shedding.
Abstract: SynopsisOne factor pair conditioned type of inflorescence. The gene for pedunculate was dominant over sub-sessile inflorescence. The symbols Se and se have been assigned to this factor pair. Inflorescence type segregated independently of flower color and growth type but was linked with maturity and height. Peduncle length, flower number per node, and percent flower shedding were inherited quantitatively with dominance and complementary gene effects toward long peduncles, high flower number, and high shedding.
