Season-dependent mineral accumulation was recorded in fruits of Okra and Tomato. The highest concentration was in summer in Okra and in winter in Tomato. Lowest concentrations were in winter in Okra and rainy in Tomato. Both crop plants indicated that the mineral contents were in the order of P > K > Ca > Mg > Na > Fe which also signify their relative functional importance in growth and metabolism. 相似文献

Phosphorus (P) is the second most important macronutrient for plant growth. Plants exhibit numerous physiological and metabolic adaptations in response to seasonal variations in phosphorus content. Activities of acid and alkaline phosphatases, ATPase and ATP content were studied in summer, rainy and winter seasons at two different developmental stages (28 and 58 days after sowing) in Okra. Activities of both acid and alkaline phosphatases increased manifold in winter to cope up with low phosphorus content. ATP content and ATPase activity were high in summer signifying an active metabolic period. Phosphorus deficiency is characterized by low ATP content and ATPase activity (which are in turn partly responsible for a drastic reduction in growth and yield) and enhanced activities of acid and alkaline phosphatases which increase the availability of P in P-deficient seasons. 相似文献
