Abstract
Selected potato (Solanum tuberosum L.) genotypes were grown in the field from May to September during 1984 and 1985, to study their growth and gas exchange responses in a warm climate. The parameters measured were leaf area index (LAI), canopy photosynthesis on ground area basis (CPn-Ga), stomatal conductance, dry matter partitioning and yield. The LAI ranged from 1.40 for Dakchip to 6.60 for Pungo during August 1984. The LAI also differed significantly among the potato genotypes for the three samplings during 1985. Atlantic, Chipbelle and DTO-33 showed no decline in their LAI up to 73 days after planting (DAP), indicating a better heat-stress tolerance response than the other genotypes. During both years, CPn-Ga differed significantly among the genotypes and Pungo had higher CPn-Ga than all the other genotypes. Mean CPn-Ga rates were 1.72 and 4.34 g CO2 m−2hr−1 during 1984 and 1985, respectively. Mean adaxial and abaxial stomatal conductances were 0.86 and 1.46 cm sec−1, during 1984, and stomatal conductances were similar for both years. Stomatal conductance did not appear to limit gas exchange in potato leaves. Dry matter partitioning to tubers ranged from 8.9% for Pungo to 55.5% for Atlantic 67 DAP during 1984. At final harvest, July 19, 1985, dry matter partitioning to tubers varied from 47.5% for Pungo to 69.9% for Chipbelle. The tuber yield ranged from 9.6 to 27.8 MT/ha. This study indicated that Atlantic and La Chipper have potential for growing in a warm climate.
Compendio
De mayo a setiembre, durante 1984 y 1985, se cultivaron genotipos selectos de papa (Solanum tuberosum L.), para estudiar su crecimiento y la respuesta al intercambio de gases en clima cálido. Los parámetros medidos fueron el índice de área de hoja (LAI), la fotosíntesis del follaje expuesto en base al área de terreno (CPn-Ga), la conductión estomática, la repartición de la materia seca, y el rendimiento. Durante agosto de 1984, la LAI varió de 1,40 para “Dakchip” a 6,60 para “Pungo.” Durante 1985, la LAI también fue significativamente diferente entre los genotipos de papa para las tres muestras estudiadas. “Atlantic,” “Chipbelle” y DTO-33 no mostraron declinatión en su LAI hasta los 73 días después de la siembra (DAP), indicando una respuesta mejor para la tolerancia al estrés al calor en comparación con los otros genotipos. Durante ambos años, la CPn-Ga difirió significativamente entre los genotipos y “Pungo” tuvo una CPn-Ga más alta que todos los otros genotipos. Durante 1984 y 1985, las tasas de CPn-Ga fueron l,72 y 4,34 g CO2 m-2hr-1,respectivamente. La conductión estomática media para las caras superior e inferior de las hojas, durante 1984, fue 0,86 y 1,46 cm sec-1, respectivamente, y fue similar para ambos años. La conductión estomática aparentemente no limitó el intercambio gaseoso en las hojas de papa. La repartición de materia seca a los tubérculos varió de 8,9% para “Pungo” a 55,5% para “Atlantic” 67 DAP, durante 1984. A la cosecha final, julio 19, 1985, la repartición de materia seca a los tubérculos varió de 47,5% para “Pungo” a 69,9% para “Chipbelle.” El rendimiento en tubérculos varió de 9,6 a 27,8 t/ha. Este estudio indicó que “Atlantic” y “La Chipper” tienen potential para ser cultivadas en clima cálido.
