Abstract
The changes n dry weight and in the content of sugars and starch of leaves of the evergreen species Prunus laurocerasus L. were studied in the field and in laboratory conditions. The leaves of field-grown bushes as well as those kept under controlled conditions were analyzed at one week intervals at the end of the winter and in early spring from March 11 to May 6, 1970, The effect of four different temperature regimes was compared (day/night) : A : — 2 to — 6 °C/ — 6°C. B: 6°C/ —6°C, C: 6 °C/6 °C and D: 12 °C/ — 6 °C. During the whole experimental period of 56 days a net increase in dry weight 246.84 mg dm-2, i.e. 21.7 % was found under field conditions. A negative balance in assimilate management was recorded only during the one week period. The total content of sugars decreased from 11.68 % to 6.42 % while the content of starch rose from zero to 3.12 %. The net increase in dry matter found under controlled conditions was 6.69 (A), 4.68 IB). 6.88 (C) and —0.43 (D) mg dm-2 d-1.
Abstract
Modifikovanou metódou listových polovíc boli v teréne aj v laboratóriu sledované zmeny suchej v—hy listov, obsahu cukrov a škrobu u stálezeleného druhu Prunus laurocerasus L. V teréne bol druh testovaný v týždenných intervaloch za prirodzených podmienok konca zimy a začiatku jari od 11. 3. do 6. 5. 1970 a v rovnakom o bdobí v laboratóriu pri teplotách (noc a deň): —6° a — 2° až —6° (variant A), —6° a +6° (B), +6° a +6° (C), —6° a +12° (D). V teréne bola za celé obdobie testovania iba v jednom týždni zistená negatívna bilanoia hospodárenia asimilatmi a suchá váha listov sa v priebehu trvania testu (za 56 dní) zvýšila o 246,84 mg dm-2, t. j. o 21,7 % Obsah celkových cukrov sa znížil z 11,08 % na 6,42 % a obsah škrobu sa zvýšil z 0,0 % na 3,12 %. V laboratórnych podmienkach dosiahol variant A prírastok 6,69, B — 4,68, C — 6,88 a D — — 0,43 mg sušiny dm-2 d-1.
