Verbatim
e0“We investigated the effects of N nutrition on growth and carbohydrate partitioning of pepper ( Capsicum annuum L., cv. Maor) seedlings in the greenhouse and on their subsequent recovery and development after transplanting”
e3“On a unit-leaf-area basis, CO 2 fixation was not affected when N was present; however, it was greatly inhibited in the absence of N”

Other claims from this paper (14)
- Intervention effect Nitrogen levels below 100 mg/liter inhibited shoot growth and leaf chlorophyll content in pepper seedlings
- Intervention effect Absence of supplemental N severely inhibited shoot growth and leaf chlorophyll content of pepper seedlings
- Association Root growth of pepper seedlings had a negative relation with N supply
- Intervention effect Low-N regimes enhanced the root:shoot ratio of pepper seedlings
- Intervention effect CO 2 fixation per unit leaf area was not affected when N was present
- Association Leaf starch and soluble sugar concentrations changed as a function of N supply and leaf age
- Intervention effect Low N led to lower sucrose in pepper roots
- Intervention effect Low N led to higher hexose and starch in pepper roots
- Intervention effect More sucrose was transported and accumulated into leaf veins of low-N tissue
- Intervention effect Exogenously supplied 14C-labeled sucrose was rapidly converted into starch in low-N tissue
- Intervention effect Seedlings grown at 100 mg N/liter had the highest post-transplant growth rate
- Intervention effect Seedlings grown at 100 mg N/liter flowered earlier
- Association Carbohydrate status of young pepper seedlings influenced their post-transplant recovery
- Recommendation Optimal N supply is essential for full recovery and development of transplanted pepper
