Title

Branch Yield Components Controlling Soybean Yield Stability across Plant Populations

A. C. Carpenter; J. E. Board Crop Science 1997. doi:10.2135/cropsci1997.0011183x003700030031x

Other claims from this paper (8)

Intervention effect A 43% population increase produced no significant soybean yield change.
Observation Branch dry matter averaged 14.0 g per plant at low population.
Observation Branch dry matter averaged 5.3 g per plant at medium population.
Observation Branch dry matter averaged 3.6 g per plant at high population.
Association Greater branch dry matter yielded more branch nodes, reproductive nodes and pods.
Association Pods per reproductive branch node affected yield in some cases.
Association Branch dry matter correlated strongly with yield at r squared 0.95.
Method / resource Branch dry matter was useful for identifying cultivars with low optimal population.

水耕ミニトマトの果実品質,収量及び生育に及ぼす塩化カリウム及び硫酸カリウム添加処理の影響

太田, 勝巳; 伊藤, 憲弘; 細木, 高志; et al. Institutional Repositories DataBase (IRDB) 1990

Other claims from this paper (12)

Intervention effect KCl increased soluble solids, sugar, acidity and fruit dry matter in three cultivars.
Intervention effect KCl decreased fruit weight in three cultivars.
Intervention effect K_2S0_4 increased fruit solids, sugar and dry matter less than KCl.
Intervention effect Fruit weight under K_2S0_4 equaled or tended to exceed control in all cultivars.
Intervention effect K_2S0_4 increased solid-acid ratio in Sun Cherry and Akakokko.
Intervention effect KCl decreased solid-acid ratio in Sun Cherry and Akakokko because acidity rose.
Observation Fruit hardness did not differ among treatments.
Intervention effect KCl decreased cherry tomato leaf length, width, mass and area.
Intervention effect Under K_2S0_4, cherry tomato leaf measures equaled or increased relative to control.
Observation Stem diameter did not differ among treatments.
Observation KCl improved fruit quality with lower yield versus the 2.0-unit control.
Observation K_2S0_4 maintained fruit quality and yield versus control.

Title

Analysis of Zinnia Capitulum Composition

Daiichiro Miyajima; Masaaki Nakayama Journal of the American Society for Horticultural Science 1994. doi:10.21273/jashs.119.4.683

Other claims from this paper (6)

Observation A capitulum accumulated fewer than 20 newly opened florets daily for more than 15 days.
Observation Kumamotonokagayaki had 210 to 330 florets per capitulum.
Observation Snowball had 220 to 290 florets per capitulum.
Observation Purple Zem had 160 to 240 florets per capitulum.
Association Tubular floret numbers were negatively correlated with ray floret numbers.
Observation Ornamentally superior capitula had more ray and fewer tubular florets than single-flowered capitula.
